A car travels the 200 miles along the M1 from London to Leeds. The car leaves London at 8am and travels at a constant speed of 60mph for the first 60 miles. The driver takes a break of 30mins at a motorway services before continuing the journey at a constant speed of 70mph a) Draw a distance-time graph of the journey

Answers

Answer 1

Answer:

The distance-time graph of the journey would be as follows:

From 8am to 8:01am, the car travels 0 miles (at 8am, it leaves London)

From 8:01am to 9:01am, the car travels 60 miles (at a constant speed of 60mph)

From 9:01am to 9:31am, the car travels 0 miles (the driver takes a break of 30mins)

From 9:31am to 12:51pm, the car travels 140 miles (at a constant speed of 70mph)

The graph would be a line with a slope of 60 for the first hour, a flat line for the 30 minutes break, and then a line with a slope of 70 for 2 hours and 20 minutes.

Note: Since we don't have a time-scale and time unit, this graph is just a representation of the pattern of the journey, and the actual values are not accurate.

given

The characteristic equation is: r2 − 3r + 2 = 0

Factor: (r − 1)(r − 2) = 0

r = 1 or 2

So the general solution of the differential equation is y = Aex+Be2x

So in this case the fundamental solutions and their derivatives are:

Find the particular solution using the formula:

yp(x) = −y1(x)∫ y2(x)f(x) /W(y1, y2) dx + y2(x)∫ y1(x)f(x) /W(y1, y2) dx

How do you know if an absolute value graph opens up or down?

Answers

An absolute value graph is a V-shaped graph that opens either upwards or downwards, depending on the equation. To determine if an absolute value graph opens up or down, you need to examine the value of the constant k in the equation. If k is positive, the graph opens upwards and if k is negative, the graph opens downwards.

The general form of an absolute value equation is y = |x| + k, where k is a constant. The graph of this equation will open upwards if k > 0, and downwards if k < 0.

For example, if the equation is y = |x| + 2, the graph will open upwards and will have vertex at the point (0, 2)

On the other hand, if the equation is y = |x| - 2, the graph will open downwards and will have vertex at the point (0,-2)

The vertex of the graph is the point where the graph changes direction. The x-coordinate of the vertex is always 0 and the y-coordinate is the value of k.

Answer:

The expression a2+a4+a6+a8+......a20 can be written in sigma notation as:

∑ a(2n) where n = 1 to 10

To expand this summation, we can substitute in the values of n and evaluate the series:

a(21) + a(22) + a(23) + ... + a(210) = a2 + a4 + a6 + ... + a20

The expression (-1) + 2 +(-3) + 4 + (-5) ....+(-25) can be written in sigma notation as:

∑ (-1)^n*n where n = 1 to 25

To expand this summation, we can substitute in the values of n and evaluate the series:

(-1)^11 + (-1)^22 + (-1)^33 + ... + (-1)^2525 = -1 + 2 - 3 + 4 - 5 +... - 25

Note that the series (-1)^n*n is an alternating series, where the signs of the terms alternate between positive and negative. This series has no closed form solution, but we can evaluate them by adding and subtracting each term.

Answer:

[tex]\displaystyle \sum_{n=1}^{10} a_{(2n)}[/tex]

[tex]\displaystyle \sum_{n=1}^{25} n (-1)^{n}[/tex]

Step-by-step explanation:

Part I

Sigma notation means the sum of the series.

Given series:

a₂ + a₄ + a₆ + a₈ + ... + a₂₀

Therefore:

First term is a₂Second term is a₄Third term is a₆

So each term is a₂ₙ

Therefore, the expression in sigma notation is:

[tex]\displaystyle \sum_{n=1}^{10}a_{(2n)}[/tex]

Given series:

(-1) + 2 + (-3) + 4 + (-5) + ... + (-25)

The absolute value of each term of the series is n.

The signs of each term alternate between negative and positive.

Therefore, the expression in sigma notation is:

[tex]\displaystyle \sum_{n=1}^{25} n (-1)^{n}[/tex]

Part II

The expansion of each summation has been given in Part I.

However, the full expansions are:

[tex]\displaystyle \sum_{n=1}^{10} a_{(2n)}=a_2+a_4+a_6+a_8+a_{10}+a_{12}+a_{14}+a_{16}+a_{18}+a_{20}[/tex]

mrs. johnson leaves on a trip planning to travel 24 mph.how fast must his son james travel to overtake himin 5 horus, if he starts 2.5 horus after his father?

Answers

Mr. Johnson leaves on a trip planning to travel with speed of 24 mph. His son leaves 2.5 hours after him. To catch his father in 5 hours, James must travel at 36 mph.

The relation between distance and speed is given by:

distance = speed x time.

In this case:

Ms' Johnson's speed = 24 mph

Mr Johnson's time = 2.5 + 5 = 7.5 hours

His travelled distance = 7.5 x 24 = 180 miles.

His son's time = 5 hours ( since he starts 2.5 hours after Mr Johnson left.)

He must catch distance of 180 miles in 5 hours. Therefore, his speed must be:

speed = distance / time

speed = 180 / 5 = 36 mph.

Hence, hisr son's speed is 36 mph.

Case 4

We need to add + 16 to both sides. (Correct choice: C)

How to use completing the square method

In this problem we find three cases of quadratic equation that are not perfect square trinomials, these equations can be rewritten partially in that form by algebra properties. Completing the square offers a quick method to determine the roots of quadratic equations with integer coefficients. Now we proceed to determine the solutions corresponding to each case:

Case 2

x² - 14 · x + 48 = 0

x² - 14 · x + 49 = 1

(x - 7)² = 1

x - 7 = ± 1

x = 7 ± 1

The roots of the quadratic equation x² - 14 · x + 48 = 0 are x₁ = 6 and x₂ = 8, respectively.

Case 3

x² - 16 · x = - 21

x² - 16 · x + 64 = 64 - 21

(x + 8)² = 43

The first step consists in adding both sides by + 64.

Case 4

x² - 8 · x = 0

x² - 8 · x + 16 = 16

(x - 4)² = 16

The first step consists in adding both sides by + 16.

What in mathematics is a polynomial?

The only operations used in a polynomial are addition, subtraction, multiplication, and non-negative integer exponentiation. In mathematics, variables are occasionally referred to as indeterminates. An example of a polynomial with a single variable x is x2 4x + 7.

The leading term of the polynomial is -2x⁴, which is negative for negative x and positive for positive x. As x approaches negative infinity, -2x⁴ approaches negative infinity, so the entire polynomial approaches negative infinity. Similarly, as x approaches positive infinity, -2x⁴ approaches positive infinity, so the entire polynomial approaches positive infinity.

Therefore, the end-behavior of the polynomial is:

f(x) → -∞, as x → -∞

f(x) →∞, as x → ∞

E) None of these

The polynomial is continuous for all real values of x. The only way for a polynomial to not be continuous is if there is a hole or a vertical asymptote in its graph.

Find the area enclosed by the curve x=t^2-2t , y = √t and the y axis.

Answers

The area enclosed by the curve x = t² - 2t, y = √(t), and the y-axis is 0.754 square units.

First, find the value of t at x = 0

x = t² - 2t

⇒ t² - 2t = 0

⇒ t(t - 2) = 0

Therefore, t = 0, t = 2.

Derivative of area, dA/dy

dA/dy = (0 - x)

dA = (0 - x) × dy

Since the curve has a negative x in this region.

y = √t (given)

dy/dt = (1/2)/√t

dA = [0 - (t² - 2t)] [(1/2)/√t]dt

dA = [2t - t²]/[(1/2)/√t]dt

dA = [[tex]t^{1/2}[/tex] - (1/2)[tex]t^{3/2}[/tex]]dt

Integrating to obtain A,

A = (2/3)[tex]t^{3/2}[/tex] - (1/5)[tex]t^{5/2}[/tex]

Now apply the limits t = 0 to t = 2

Area = [(2/3)[tex]2^{3/2}[/tex] - (1/5)[tex]2^{3/2}[/tex]] - [0]

Area = √[2(4/3 - 4/5)]

Area = √[2(8/15)]

Area = √(16/15)

Area = 0.754

Thus, the area enclosed by the given curves is 0.754 square units.

Find the Taylor polynomial T3(x) for the function f centered at the number a.
f(x) = x + e−x, a = 0
T3(x)=?

Answers

T3(x) = x - x^2/2 + x^3/6.

The Taylor polynomial of degree 3 for the function f(x) = x + e^-x centered at a = 0 is given by:

T3(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3

= 1 + (-1 + 1)x + (e^-0 - (-1)(-1)e^-0)x^2/2! + (0 + (-1)(-1)(-1)e^-0)x^3/3!

= x - x^2/2 + x^3/6

So T3(x) = x - x^2/2 + x^3/6.

An infinite sum of words that are expressed in terms of a function's derivatives at a single point is known as the Taylor series or Taylor expansion of a function in mathematics.

The nth Taylor polynomial of the function is a polynomial of degree n that is created by the partial sum of the first n + 1 terms of a Taylor series. Approximations of a function made by Taylor polynomials get generally better as n rises. Quantitative estimates of the mistake brought about by the use of such approximations are provided by Taylor's theorem. If a function's Taylor series is converging, its total is the upper bound of the Taylor polynomials' infinite sequence. A function's Taylor series sum may not match.
