Answers

Answer 1

The equation for the linear function f(x) is f(x) = x + 4.

A linear function can be represented by the equation f(x) = mx + b, where m is the slope and b is the y-intercept. To find the equation for f(x) given the values f(-4) = -4 and f(2) = 0, we can substitute these values into the equation.

First, we substitute x = -4 and f(x) = -4 into the equation:

-4 = -4m + b

Next, we substitute x = 2 and f(x) = 0 into the equation:

0 = 2m + b

Now we have a system of two equations with two variables (-4m + b = -4 and 2m + b = 0). To solve this system, we can subtract the second equation from the first equation to eliminate b:

(-4m + b) - (2m + b) = -4 - 0

-6m = -4

Simplifying the equation, we get:

m = 2/3

Substituting this value of m into either of the original equations, we can solve for b:

0 = 2(2/3) + b

0 = 4/3 + b

b = -4/3

Therefore, the equation for f(x) is f(x) = (2/3)x - 4/3.

Answers

The orthogonal trajectories of the family of curves y^6=kx^4 are given by x^2=cy^2, where c is a constant value. Therefore, the correct answer is (C) 2y^2+3x^2=C.

Orthogonal trajectories of a family of curves is a family of curves that intersect each member of the given family of curves at right angles.

The family of curves y^6=kx^4 can be written as y^2=±√(k) x^2, then the slope of each curve of the family of curves is given by y' = ±√(k) x/ (y/2), which can also be expressed as y' = ±2 √(k) x/y.

The negative reciprocal of the slope of the given family of curves is given by -y/2 √(k) x.

Hence, the slope of the orthogonal trajectories of the family of curves is given by 2y/√(k) x.

Substituting this in the differential equation, we have, y' = dy/dx = 2y/√(k) x.

Thus, the differential equation of the orthogonal trajectories is given by x dy/dx - y/2 = 0, which can be rewritten as dx/dy = 2y/x.

Integrating, we have x^2 = cy^2, where c is a constant of integration.

Thus, the orthogonal trajectories of the family of curves y^6=kx^4 are given by x^2=cy^2, where c is a constant value. Hence, the correct answer is (C) 2y^2+3x^2=C.

Final Answer: The orthogonal trajectories of the family of curves y^6=kx^4 are given by x^2=cy^2, where c is a constant value. Therefore, the correct answer is (C) 2y^2+3x^2=C.

Answers

To graphically determine the resultant of the three vector displacements, we need to create a vector diagram. However, since this is a text-based platform, I am unable to provide a graphical representation directly. I will provide you with a step-by-step explanation instead.

Start by drawing a coordinate system with the x-axis representing east and the y-axis representing north. Mark the origin as O.

For the first vector displacement, draw a line segment of length 24 units (scale is arbitrary) at an angle of 36 degrees north of east (clockwise from the positive x-axis).

For the second vector displacement, draw a line segment of length 18 units at an angle of 37 degrees east of north (clockwise from the positive y-axis). The starting point of this line segment should coincide with the endpoint of the first line segment.

For the third vector displacement, draw a line segment of length 26 units at an angle of 33 degrees west of south (clockwise from the positive y-axis). The starting point of this line segment should coincide with the endpoint of the second line segment.

Connect the starting point of the first line segment (O) with the endpoint of the third line segment. This represents the resultant vector displacement.

By following the steps outlined above and drawing the vector diagram, you will be able to graphically determine the resultant of the three vector displacements. The resultant vector represents the combined effect of the individual displacements and can be determined by connecting the starting point of the first vector to the endpoint of the last vector in the diagram.

A rain gutter along the edge of a roof has the shape of a rectangular prism. It is 7 inches high, 3 inches wide, and 21 feet long. How much water can the gutter hold in cubic inches? in gallons? Use t

Answers

The rain gutter can hold a volume of 441 cubic inches (in³) and approximately 12.03 gallons (gal) of water.Therefore, the rain gutter can hold approximately 441 cubic inches or 12.03 gallons of water.

To find the volume of the rain gutter, we multiply its dimensions: height × width × length. Given that the height is 7 inches, the width is 3 inches, and the length is 21 feet (which we convert to inches by multiplying by 12), we have: Volume = 7 in × 3 in × 21 ft × 12 in/ft = 441 in³.

To convert the volume from cubic inches to gallons, we need to know the conversion factor. There are approximately 231 cubic inches in one gallon. Thus, dividing the volume in cubic inches by 231, we get:

Volume in gallons = 441 in³ ÷ 231 = 1.91 gal (rounded to two decimal places).

Find the net change in velocity over the time interval [3,9] for an object if the rate of change of its velocity is a (t)=23t−2t2 (in m/s2). (Round your answer to two decimal piaces).

Answers

Therefore, the net change in velocity over the time interval [3, 9] is 10 m/s.

To find the net change in velocity over the time interval [3, 9], we need to integrate the rate of change of velocity function [tex]a(t) = 23t - 2t^2[/tex] with respect to time over that interval.

The integral of a(t) with respect to t gives us the change in velocity function v(t):

v(t) = ∫a(t) dt.

Integrating [tex]a(t) = 23t - 2t^2[/tex], we get:

[tex]v(t) = 23(t^2/2) - (2t^3/3) + C,[/tex]

where C is the constant of integration.

Now, to find the net change in velocity over the interval [3, 9], we evaluate v(t) at the upper and lower bounds:

Δv = v(9) - v(3).

Substituting the values into the equation, we have:

[tex]Δv = [23(9^2/2) - (2(9^3)/3) + C] - [23(3^2/2) - (2(3^3)/3) + C].[/tex]

Simplifying the expression, we get:

Δv = [207/2 - 486/3] - [103/2 - 54/3]

= [207/2 - 162] - [103/2 - 18]

= 207/2 - 162 - 103/2 + 18

Answers

The dimensions of the smaller deck are l = 75 feet and w = 37.5 feet while the dimensions of the larger deck are 225 feet and 37.5 feet. Let's consider the length and width of the smaller deck be l and w respectively.

Area of the smaller deck = lw. According to the question, the length of the larger deck is three times the length of the smaller deck.

Therefore, the length and width of the larger deck are 3l and w, respectively.

Area of the larger deck = 3l*w. Now, given that the smaller deck has an area and it is equal to the area of the larger deck minus 150 square feet. So, we have;l*w = 3l*w - 150 or2lw = 150l = 75. Dividing by 2, we get the value of w as;w = 75/2 = 37.5 feet

Therefore, the length of the larger deck is 3l = 3*75 = 225 feet. Hence, the dimensions of the smaller deck are l = 75 feet and w = 37.5 feet while the dimensions of the larger deck are 225 feet and 37.5 feet.

In a murder investigation, the temperature of the corpse was 35∘C at 1:30pm and 25∘C4 hours later. Normal body temperature is 37∘C and the surrounding temperature was 7∘C. How long (in hours) before 1:30pm did the murder take place?

Answers

Therefore[tex],\[t=\frac{\ln |T_{1}-T_{s}|-\ln |T_{0}-T_{s}|}{k}=\frac{\ln \frac{28}{37-7}-\ln \frac{35-7}{37-7}}{\ln |25-7|-\ln |35-7|}\approx 8.6 \mathrm{~hours}\][/tex] before 1:30 pm did the murder take place, by proper investigation.

In a murder investigation, the temperature of the corpse was 35∘C at 1:30 pm and 25∘C 4 hours later.

Normal body temperature is 37∘C and the surrounding temperature was 7∘C.

We are to find how long before 1:30 pm did the murder take place?Let's suppose that the temperature of the corpse at the time of death was the normal body temperature.

So the temperature of the surrounding would be 37∘C since the corpse was inside a body which was warmer than the surrounding.

Using Newton's law of cooling, the rate at which the temperature of the corpse is changing is proportional to the difference between the temperature of the corpse and the temperature of the surrounding.

Therefore,[tex]\[\frac{d T}{d t}=k\left(T-T_{s}\right)\][/tex] Where T is the temperature of the corpse, Ts is the surrounding temperature and k is a constant of proportionality.

By separating the variables[tex],\[\int \frac{d T}{T-T_{s}}=\int k d t\]We get\[\ln |T-T_{s}|=kt+C\][/tex] where C is a constant of integration.

At t = 0, T = T0. Hence,[tex]\[\ln |T_{0}-T_{s}|=C\][/tex] So we have,[tex]\[\ln \left|T-T_{s}\right|=kt+\ln \left|T_{0}-T_{s}\right|\][/tex]Let T1 be the temperature of the corpse after t time.

Then we can write,[tex]\[\ln \left|T_{1}-T_{s}\right|=kt+\ln \left|T_{0}-T_{s}\right|\][/tex] Therefore,[tex]\[k=\frac{\ln \left|T_{1}-T_{s}\right|-\ln \left|T_{0}-T_{s}\right|}{t}\][/tex]

From the question, we know that the temperature of the corpse was 35 ∘C at 1:30 pm and 25∘C 4 hours later.

Hence[tex],\[k=\frac{\ln |25-7|-\ln |35-7|}{4}\][/tex] Substituting the value of k in the equation for T(t),

we get[tex]\[T=7+\left(35-7\right) e^{-\frac{1}{4} \ln \frac{25-7}{35-7}}=7+28 e^{-\frac{1}{4} \ln \frac{25-7}{28}}\][/tex]

We know that at the time of death, the temperature of the corpse was 37∘C.

Therefore,[tex]\[37=7+28 e^{-\frac{1}{4} \ln \frac{25-7}{28}}\][/tex]

Solving for ln(x),

we get [tex]\[e^{-\frac{1}{4} \ln \frac{25-7}{28}}=\frac{37-7}{28}\][/tex]Hence, [tex]\[-\frac{1}{4} \ln \frac{25-7}{28}=\ln \frac{28}{37-7}\][/tex]

Answers

To approximate the value of f(x, y, z) = √x(2y + z) at point P(1.1, 2.1, 1.1), we can use differentials. Additionally, we need to find and classify the stationary points of the function f(x, y) = x^3 − 27x + y^3 − 12y − 12.

To approximate the value of f(x, y, z) = √x(2y + z) at the point P(1.1, 2.1, 1.1) using differentials, we can start by calculating the partial derivatives of f with respect to x, y, and z. Let's denote the partial derivatives as ∂f/∂x, ∂f/∂y, and ∂f/∂z, respectively. Then, we can use the differentials to approximate the change in f near point P as:

Δf ≈ (∂f/∂x)Δx + (∂f/∂y)Δy + (∂f/∂z)Δz,

where Δx, Δy, and Δz are small changes in x, y, and z, respectively. Plugging in the values ∂f/∂x, ∂f/∂y, and ∂f/∂z evaluated at P and the corresponding small changes, we can approximate the value of f(P).

Moving on to the second question, we need to find and classify the stationary points of the function f(x, y) = x^3 − 27x + y^3 − 12y − 12. Stationary points occur where the partial derivatives ∂f/∂x and ∂f/∂y are both zero. By finding these points and classifying them as local maxima, local minima, or saddle points, we can determine the extrema of the function. This classification can be done by analyzing the second partial derivatives of f using the second derivative test.

Two functions are given. They are F1(x) and F2(x). We have to determine whether any of these functions are the anti-derivatives of the function f(x) = x²-2x+4.

The given function is f(x) = x²-2x+4. An antiderivative of a function f(x) is the function F(x) such that F'(x) = f(x). Here, we are given two functions F1(x) and F2(x), we need to check whether any of them satisfies the given condition to be the antiderivative of the function f(x). Let's first calculate the derivative of F1(x):F1'(x) = d/dx [1/3(x+1)^3+3x+9] = (x+1)^2+3 = x²+2x+4We can see that F1'(x) is not equal to f(x) = x²-2x+4.

Given the demand function q(p) = 150 – p^2 with domain 0 ≤ p ≤ √150
(a) Find the Price Elasticity of Demand function, E(p).
(b) Find ∣E(p)∣.
(c) When is ∣E(p)∣=1 ?
(d) When is price Inelastic?

Answers

(a) The Price Elasticity of Demand function, E(p), can be found by differentiating the demand function with respect to price and multiplying it by the ratio of price to quantity.

(b) ∣E(p)∣ is the absolute value of the Price Elasticity of Demand function.

(c) ∣E(p)∣=1 when the Price Elasticity of Demand is equal to 1, indicating unit elasticity.

(d) Price is inelastic when the absolute value of the Price Elasticity of Demand is less than 1, indicating a relatively low responsiveness of quantity demanded to price changes.

Explanation:

(a) To find the Price Elasticity of Demand function, E(p), we need to differentiate the demand function q(p) = 150 - p^2 with respect to price, p. Differentiating q(p) with respect to p gives us q'(p) = -2p. Then, multiplying q'(p) by the ratio of price to quantity, we have E(p) = (p/q) * q'(p) = (p/(150 - p^2)) * (-2p).

(b) ∣E(p)∣ represents the absolute value of the Price Elasticity of Demand function. In this case, it is the absolute value of (p/(150 - p^2)) * (-2p), which simplifies to 2p^2 / (p^2 - 150).

(c) To find when ∣E(p)∣ = 1, we set the absolute value of the Price Elasticity of Demand function equal to 1 and solve for p. So, |(p/(150 - p^2)) * (-2p)| = 1. This equation can be rearranged to |2p^2| = |(p^2 - 150)|. Since the absolute value of a squared term is always positive, we can simplify this equation to 2p^2 = p^2 - 150. Solving for p, we find p = ±√150.

(d) Price is considered inelastic when the absolute value of the Price Elasticity of Demand is less than 1. So, for |E(p)| < 1, we need 2p^2 / (p^2 - 150) < 1. Multiplying both sides by (p^2 - 150), we get 2p^2 < p^2 - 150. Simplifying further, we have p^2 > 150. Taking the square root of both sides, we find p > √150. Therefore, when price is greater than the square root of 150, the demand is considered price inelastic.

In this equation, [0, 5] represents a point on the line (the y-intercept) where the line crosses the y-axis. The vector [1, -3] represents the direction vector of the line, which indicates how the line extends in the x and y directions.

By introducing the parameter t, we can generate a series of points along the line by varying its value. When t = 0, the resulting point will be the y-intercept [0, 5]. As t increases or decreases, the vector t[1, -3] scales the direction vector, effectively moving along the line. Thus, for any chosen value of t, the expression [0, 5] + t[1, -3] will give us a point on the line.

g(t) = sin (2pit) rect(t/7) The given function is :__________

Answers

The given function g(t) = sin(2πt) rect(t/7) is a periodic waveform that resembles a sine wave with a period of 7 units, but with its oscillations restricted to the interval [-3.5, 3.5].

The given function is a product of two functions: g(t) = sin(2πt) rect(t/7).

The first function, sin(2πt), represents a sine wave with a period of 1, oscillating between -1 and 1. It completes one full cycle within the interval [0, 1]. The 2π factor in front of t determines the frequency of the sine wave, which in this case is one complete cycle per unit interval.

The second function, rect(t/7), represents a rectangular pulse or a square wave. It has a width of 7 units and is centered at t = 0. The rect function has a value of 1 within the interval [-3.5, 3.5] and 0 elsewhere.

Multiplying these two functions together, g(t) = sin(2πt) rect(t/7), results in a waveform that combines the characteristics of both functions. It essentially creates a sine wave that is only active or "on" within the interval [-3.5, 3.5]. Outside this interval, the function is zero. This effectively truncates the sine wave and creates a periodic waveform that repeats every 7 units.

In summary, the given function g(t) = sin(2πt) rect(t/7) is a periodic waveform that resembles a sine wave with a period of 7 units, but with its oscillations restricted to the interval [-3.5, 3.5].

The categorical syllogism "All meticulously constructed timepieces are true works of art" is invalid. A counterexample can be found by considering a meticulously constructed timepiece that lacks aesthetic value.

To use the counterexample method to prove the categorical syllogism "All meticulously constructed timepieces are true works of art, for all Swiss watches are true works of art and all Swiss watches are meticulously constructed timepieces" invalid, we need to find a counterexample that shows the conclusion is false even if the premises are true. Let's consider a scenario in which there is a meticulously constructed timepiece that is not a true work of art. This would be a counterexample to the conclusion, since the conclusion asserts that all meticulously constructed timepieces are true works of art.

For example, suppose that there is a meticulously constructed timepiece that is made with the sole purpose of accurate timekeeping, and has no aesthetic value. This timepiece can be considered a counterexample to the conclusion, since it is meticulously constructed but not a true work of art.

To find the polar coordinates (r, θ) from the given Cartesian coordinates (x, y), we use the following conversions:

r = √(x^2 + y^2)

θ = arctan(y/x)

(a) For (x, y) = (3, 7):

3) Evaluate the sum of the infinite geometric series:
1/2 + 1/4 + 1/8 + 1/16 +⋯

Answers

The sum of the infinite geometric series is 1.

1) For the arithmetic sequence: −16,−12,−8,−4,⋯

a) The general term of an arithmetic sequence is given by the formula:

a_n = a_1 + (n - 1)d

Where a_1 is the first term and d is the common difference between the terms.

So for the sequence given, a_1 = -16 and d = 4.

Therefore, a_n = -16 + 4(n - 1)

= -4n - 12

b) The formula to find the sum of n terms of an arithmetic sequence is:

S_n = n/2 [2a_1 + (n - 1)d]

Given

S_n = 440

a_1 = -16

d = 4,

we can use the formula to solve for n:

440 = n/2 [2(-16) + 4(n - 1)]

440 = n[-32 + 4n - 4]

440 = 4n² - 28n

440 = 4n(n - 7)

110 = n(n - 7)

0 = n² - 7n + 110

0 = (n - 10)(n - 1)

n = 10 or

n = 1

However, since the sequence is increasing, hence n = 10 is correct.

2) For the geometric sequence: 1,3,8,⋯

a) The general term of a geometric sequence is given by the formula:

a_n = a_1r^(n-1)

Where a_1 is the first term and r is the common ratio between the terms.

So for the sequence given, a_1 = 1 and r = 3/1.

Therefore,a_n

= 1(3)^(n - 1)

= 3^(n - 1)

b) The formula to find the sum of n terms of a geometric sequence is:

S_n = a_1(1 - r^n) / (1 - r)

Given S_n = 440

a_1 = 1

r = 3,

we can use the formula to solve for n:

440 = 1(1 - 3^n) / (1 - 3)

440 = (3^n - 1) / (-2)

880 = 1 - 3^n3^n

= -879n

= log(879) / log(3)

≈ 6.634

So n ≈ 7.3

However, since we are dealing with a sequence, we must round up to the nearest integer, which gives n = 8.

3) The sum of the infinite geometric series 1/2 + 1/4 + 1/8 + 1/16 + ⋯ is given by the formula:

S = a_1 / (1 - r)

Where a_1 is the first term and r is the common ratio between the terms.

In this case, a_1 = 1/2 and r = 1/2.

Therefore,S = (1/2) / (1 - 1/2) which is 1

f(x) = tan )2x)
f9x) = 5/(e^x – 2)
f(x) = (x+1)/(x^2 + 1)

Answers

The functions that have removable discontinuity are f(x) = (x+1)/(x² + 1) and f(t) = t⁻¹ + 1.

Explanation: Discontinuity is a term that means a break in the function.

Discontinuity may be caused by vertical asymptotes, holes, and jumps.

Removable discontinuity happens when there is a hole at a certain point.

The function has no value at that point, but a nearby point has a finite value.

The denominator of the given function f(x) = (x² + 1) has no real roots.

Therefore, the function is continuous everywhere.

There is no point in the function that has a removable discontinuity.

Hence, f(x) = x/ (x² + 1) has no removable discontinuity.

The given function f(t) = t⁻¹ + 1 is a rational function that can be rewritten as f(t) = (1 + t)/ t.

The point where the function has a removable discontinuity is at t = 0.

Hence, the function f(t) = t⁻¹ + 1 has a removable discontinuity.

The denominator of the given function f(t) = (t² + 5t + 6) has roots at t = -2 and t = -3.

Therefore, the function has vertical asymptotes at t = -2 and t = -3.

There are no points where the function has a removable discontinuity.

Hence, f(t) = (t + 3)/ (t² + 5t + 6) has no removable discontinuity.

The function f(x) = tan 2x has vertical asymptotes at x = π/4 + kπ/2, where k is an integer.

There is no point in the function that has a removable discontinuity.

Hence, f(x) = tan 2x has no removable discontinuity.

The given function f(x) = 5/(e^x – 2) has an asymptote at x = ln 2.

The function has no point where it has a removable discontinuity.

Hence, f(x) = 5/(e^x – 2) has no removable discontinuity.

The given function f(x) = (x+1)/(x² + 1) has a hole at x = -1.

Hence, the function f(x) = (x+1)/(x² + 1) has a removable discontinuity.

An object is moving along a horizontal axis with a velocity of v(t) = 0.5t^3 — 4t^2 + 5t + 2 where v(t) is measured in feet per second and t is seconds. Round to three decimal places when applicable.

a) Write the acceleration equation: a(t) = ______
b) Find the time(s) when the object is stopped. t = ______
c) Find the subintervals in (0,10) when the object is moving left and right.
Moving left: ______
Moving right : ______

Answers

The acceleration equation of the object is a(t) = 1.5t² - 8t + 5.The times when the object is stopped are t = -2, t = 0.561, and t = 4.439. The object moves right in the interval (0, 1) and left in the interval (5, 10).

a) The given velocity function is:

v(t) = 0.5t³ - 4t² + 5t + 2

The derivative of v(t) gives the acceleration of the function.

v′(t) = a(t)

On differentiating v(t), we get

a(t) = v′(t) = 1.5t² - 8t + 5

Thus, the acceleration equation of the object is given by a(t) = 1.5t² - 8t + 5

b) The time when the object is stopped is when the velocity is zero.

The velocity function of the object is given as:

v(t) = 0.5t³ - 4t² + 5t + 2

To find the time when the object is stopped, we need to solve for the roots of the function.

0 = v(t) = 0.5t³ - 4t² + 5t + 2

Using synthetic division, we find that -2 is a root of the function.

Now, we can factor the function:

v(t) = (t + 2)(0.5t² - 5t + 1)

For the function 0.5t² - 5t + 1, we can solve for the roots using the quadratic formula.

t = (5 ± √(5² - 4(0.5)(1)))/1

t = (5 ± √17)/1

Thus, the time the object is stopped is given by t = -2, t = 0.561, and t = 4.439 (to three decimal places).

c) To determine the subintervals where the object is moving left and right, we need to examine the sign of the velocity function. If v(t) < 0, then the object is moving left, and if v(t) > 0, then the object is moving right. If v(t) = 0, then the object is at rest. The velocity function of the object is:

v(t) = 0.5t³ - 4t² + 5t + 2We need to determine the sign of v(t) in the interval (0, 10).We can use test points to determine the v(t) sign.

Testing for a value of t = 1:

v(1) = 0.5(1)³ - 4(1)² + 5(1) + 2

= 3.5

Since v(1) > 0, the object is moving right at t = 1.

Testing for a value of t = 5:

v(5) = 0.5(5)³ - 4(5)² + 5(5) + 2

= -12.5

Since v(5) < 0, the object moves left at t = 5.

Thus, the object moves right in the interval (0, 1) and left in the interval (5, 10).

Therefore, the acceleration equation of the object is a(t) = 1.5t² - 8t + 5. The time the object is stopped is t = -2, t = 0.561, and t = 4.439. The object moves right in the interval (0, 1) and left in the interval (5, 10).

By substituting the given values into the function and simplifying, we obtained the simplified expression (7h) / [2(-2+h)].

To simplify the given difference quotient, let's start by evaluating g(-3+h) and g(-3).

Given: g(x) = 7/(x+1)

Evaluating g(-3+h):

Replace x with (-3+h) in the function g(x):

g(-3+h) = 7/((-3+h)+1)

= 7/(-2+h)

Evaluating g(-3):

Replace x with -3 in the function g(x):

g(-3) = 7/(-3+1)

= 7/(-2)

= -7/2

Now, substitute these values into the difference quotient and simplify:

[g(-3+h) - g(-3)] / h

= [7/(-2+h) - (-7/2)] / h

= [7/(-2+h) + 7/2] / h

To simplify the expression further, we can find a common denominator for the two fractions in the numerator:

= [7(2) + 7(-2+h)] / [2(-2+h)]

= [14 - 14 + 7h] / [2(-2+h)]

Answers

The value is "λ = 77/75".

Given two lines asx−1=(y+1​)/2 =(z−1​)/λ and x+1=y−1=z

Now, let's solve the equations as follows:

x - 1 = (y + 1) / 2 = (z - 1) / λ => (1)

y - 1 = x + 1 = z => (2)

From (2), we have

y - 1 = x + 1 --------------(3)and

z = x + 1-------------------------(4)

Substitute (3) and (4) in (1), we have

y - 1 = (x + 1) / 2 = (x + 1) / λ

=> λ (y - 1) = x + 1

=> λy - x = λ + 1 ------------(5)

Now, substituting (3) in (5), we get

λ (y - 1) = y + 2

=> λy - y = λ + 2

=> (λ - 1) y = λ + 2

=> y = λ + 2 / λ - 1 -----------------(6)

Substitute (6) in (3), we get

λ + 2 / λ - 1 - 1 = x

=> λ + 2 - λ + 1 / λ - 1 = x

=> λ + 3 / λ - 1 = x -------------(7)

Substitute (7) in (4), we have

z = λ + 4 / λ - 1 ------------------(8)

Now, since both lines intersect each other, they must coincide.

Hence their direction ratios must be proportional.

Therefore, we can say

λ + 4 / λ - 1

Answers

Therefore, the absolute extrema of the function [tex]g(x) = x - 29x^2[/tex] on the closed interval [-2, 1] are: Minimum: (-2, -118) and Maximum: (1/58, -0.986).

To find the absolute extrema of the function [tex]g(x) = x - 29x^2[/tex] on the closed interval [-2, 1], we need to evaluate the function at the critical points and endpoints within the interval.

Critical Points:

To find the critical points, we need to find where the derivative of g(x) is equal to zero or does not exist.

g'(x) = 1 - 58x.

Setting g'(x) = 0, we have:

1 - 58x = 0,

58x = 1,

x = 1/58.

Since x = 1/58 lies within the interval [-2, 1], we consider it as a critical point.

Endpoints:

We evaluate g(x) at the endpoints of the interval:

[tex]g(-2) = (-2) - 29(-2)^2[/tex]

= -2 - 116

= -118

[tex]g(1) = (1) - 29(1)^2[/tex]

= 1 - 29

= -28

Comparing Values:

Now, we compare the values of g(x) at the critical point and endpoints to determine the absolute extrema.

g(1/58) ≈ -0.986.

g(-2) = -118.

g(1) = -28.

The absolute minimum occurs at x = -2 with a value of -118, and the absolute maximum occurs at x = 1/58 with a value of approximately -0.986.

To evaluate the indefinite integral ∫(−10x+1)e²ˣ−¹⁰ˣ²−⁴dx, we can rewrite it in terms of the substitution u=2x−10x²−4 and then integrate with respect to u.

Let's rewrite the integral using the substitution u=2x−10x²−4. To do this, we need to express dx in terms of du. Differentiating u with respect to x gives du/dx=2−20x, which implies dx=du/(2−20x). We can substitute these expressions into the original integral to obtain ∫(−10x+1)e²ˣ−¹⁰ˣ²−⁴dx = ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴(du/(2−20x)).

Simplifying this expression, we have ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴(du/(2−20x)) = ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴du/(2−20x). Now, we can factor out the common term (2−20x) from the numerator, resulting in ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴du/(2−20x) = ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴du/2(1−10x).

Now, the integral can be evaluated easily with respect to u, as the expression inside the integral no longer contains x. The resulting integral is ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴du/2(1−10x). Finally, we integrate with respect to u and replace u with the original expression 2x−10x²−4, giving the final result in terms of u: ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴dx = ∫(-10x+1)e²ˣ−¹⁰ˣ²−⁴du/2(1−10x).

B) Find the flux through the surface of a cylinder with 2 ≤ z ≤ 5 and p = 2 by evaluating the left and right side of the divergence theorem. Assume that D=p² ap [8 marks] A Go

Answers

The cylinder has a height between 2 and 5 units along the z-axis, and a radius of 2 units. The electric displacement vector D is given by D = p² ap, where p is the magnitude of the position vector.

The divergence theorem relates the flux of a vector field through a closed surface to the divergence of the vector field within the volume enclosed by that surface. In this case, we need to find the flux through the surface of a cylinder.

To evaluate the left side of the divergence theorem, we integrate the dot product of the vector field (D) and the outward-pointing unit normal vector (dS) over the surface of the cylinder. The unit normal vector dS represents the differential area element on the surface. By performing this integration, we obtain the flux through the surface of the cylinder.

On the right side of the divergence theorem, we evaluate the divergence of the vector field D within the volume enclosed by the cylinder. The divergence measures the rate at which the vector field spreads out or converges at a given point. By computing the divergence and integrating it over the volume of the cylinder, we determine the flux through the surface.    

By comparing the results of both evaluations, we can confirm the validity of the divergence theorem.

Find the derivative of the following function. y= 9x^3/Inx

Answers

The derivative of the function is y' = (27x² ln(x) - 9x²) / (ln(x))²

Given data:

To find the derivative of the function y = (9x³) / ln(x), we can use the quotient rule.

The quotient rule states that if we have a function in the form f(x) / g(x), where f(x) and g(x) are differentiable functions, the derivative is given by:

(f'(x) * g(x) - f(x) * g'(x)) / (g(x))²

Let's apply the quotient rule to the given function:

f(x) = 9x³

g(x) = ln(x)

f'(x) = 27x² (derivative of 9x³ with respect to x)

g'(x) = 1/x (derivative of ln(x) with respect to x)

Now we can substitute these values into the quotient rule formula:

y' = ((27x²) * ln(x) - (9x³) * (1/x)) / (ln(x))²

Simplifying further:

y' = (27x² ln(x) - 9x²) / (ln(x))²

Hence , the derivative of the function y = (9x³) / ln(x) is:

y' = (27x² ln(x) - 9x²) / (ln(x))²
