Answer:

x - 3y = 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x + 4 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

to find c substitute (3, - 2 ) into the partial equation

- 2 = [tex]\frac{1}{3}[/tex] (3) + c = 1 + c ( subtract 1 from both sides )

- 3 = c

y = [tex]\frac{1}{3}[/tex] x - 3 ← equation in slope- intercept form

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

multiply the equation through by 3 to clear the fraction

3y = x - 9 ( subtract x from both sides )

- x + 3y = - 9 ( multiply through by - 1 )

x - 3y = 9 ← equation in standard form

The school record in the long jump is 518 cm  third graph (open circle on 518, colored to the right). represents the set of jump distances, in centimeters, that would set a new school record

Distance is a measure of the physical or spatial separation between two objects or points. It quantifies the amount of space between them and is typically expressed in units such as meters, kilometers, miles, or any other suitable unit of length. There are various methods to measure distance, depending on the context and available tools. For shorter distances, you can use a ruler, measuring tape, or a laser distance meter. For longer distances, techniques like triangulation, GPS (Global Positioning System), or specialized surveying equipment may be employed.

In the graph, a vertical line is drawn at 518 cm with an open dot to represent that 518 cm is not included in the set of jump distances for the new record. To the right of the line, an arrow indicates that the jump distances should be greater than 518 cm to set a new school record.

The school record in the long jump is 518 cm. Now we need to find the graph represents the set of jump distances in centimeters that would set a new school record. Here, school already set a record in the long jump i.e  518 cm, it means anything less then or equal to the 518 cm is not a record .As we need to exclude the numbers 518. So use an open dot at 518. For record the distances should be greater than 518 cm. Thus, use the arrow moving right to 518.

The 95% confidence interval for the population mean ≈ (97.32, 102.28).

To determine the 95% confidence interval for the population mean, we can use the formula:

Confidence Interval = sample mean ± (critical value) * (standard deviation / sqrt(sample size))

We have:

Sample mean (xbar) = 100.3

Standard deviation (σ) = 10

Sample size (n) = 43

First, we need to obtain the critical value associated with a 95% confidence level. This can be obtained from a standard normal distribution table or using a calculator.

For a 95% confidence level, the critical value is approximately 1.96.

Plugging in the values into the formula, we have:

Confidence Interval = 100.3 ± (1.96) * (10 / sqrt(43))

Calculating the expression:

Confidence Interval = 100.3 ± (1.96) * (10 / sqrt(43))

                  ≈ 100.3 ± (1.96) * (10 / 6.56)

                  ≈ 100.3 ± (1.96) * 1.52

                  ≈ 100.3 ± 2.98

Rounding the answers to the nearest hundredth:

Lower bound = 100.3 - 2.98 ≈ 97.32

Upper bound = 100.3 + 2.98 ≈ 102.28

Therefore, the 95% confidence interval is approximately (97.32, 102.28).

The function F(x) satisfies the property that for any value of x, F(-x) = -F(x). Geometrically, an odd function has symmetry with respect to the origin, meaning that if we reflect the graph of the function across the y-axis, we get the same graph back but "flipped" over the x-axis.

To determine if F(x) is odd, even or neither, we need to check whether F(-x) is equal to -F(x) for all x.

First, we use the identity sec(-x) = sec(x) to rewrite sec(-x) as sec(x). Next, we use the identity sin(-x) = -sin(x) to rewrite sin(-x) as -sin(x).

Substituting these expressions into F(-x), we get:

F(-x) = 3(sec(-x))(sin(-x))

= 3(sec(x))(-sin(x))

= -3(sec(x))(sin(x))

Comparing this with F(x) = 3(sec(x))(sin(x)), we see that F(-x) = -F(x). This means that the function F(x) is an odd function.

In other words, the function F(x) satisfies the property that for any value of x, F(-x) = -F(x). Geometrically, an odd function has symmetry with respect to the origin, meaning that if we reflect the graph of the function across the y-axis, we get the same graph back but "flipped" over the x-axis.

Answer:

The y-intercept is (0, -3).

The axis of symmetry is x=3/4.

The vertex is  (3/4, -21/4).

Step-by-step explanation:

We are given the following quadratic function.

[tex]f(x)=4x^2-6x-3[/tex]

And we are asked to determine the following:

[tex]\hrulefill[/tex]

To find the y-intercept, axis of symmetry, and vertex of a quadratic function, you can follow these steps:

(1) - Identify the quadratic function: Determine the quadratic function for which you want to find the y-intercept, axis of symmetry, and vertex. It is usually given as an equation or described in a problem.

(2) - Y-intercept: To find the y-intercept, substitute x = 0 into the quadratic function and evaluate the expression. The resulting value represents the y-coordinate of the point where the graph intersects the y-axis.

(3) - Axis of symmetry: The axis of symmetry is a vertical line that passes through the vertex of the quadratic function. To find the axis of symmetry, you can use one of the following methods:

(4) - Vertex: The vertex of a quadratic function represents the highest or lowest point on the graph (the maximum or minimum point). To find the vertex, you can use one of the following methods:

[tex]\hrulefill[/tex]

Step (1) -

[tex]f(x)=4x^2-6x-3[/tex]

Step (2) -

[tex]\Longrightarrow f(0)=4(0)^2-6(0)-3\\\\\\\therefore \boxed{f(0)=-3}[/tex]

Thus, the y-intercept is (0, -3).

Step (3) -

The given function is in standard form. Thus, we can use the following formula:

[tex]x=\dfrac{-b}{2a}; \ \text{In our case:} \ b=-6 \ \text{and} \ a=4\\ \\\\\Longrightarrow x=\dfrac{-(-6)}{2(4)}\\\\\\\Longrightarrow x=\dfrac{6}{8}\\\\\\\therefore \boxed{x=\frac{3}{4} }[/tex]

Thus, the axis of symmetry is found.

Step (4) -

Recall that we were given a function in standard form and in step 3 we found that x=3/4.

[tex]\Longrightarrow f(\frac{3}{4} )=4(\frac{3}{4})^2-6(\frac{3}{4} )-3\\\\\\\Longrightarrow f(\frac{3}{4} )=\dfrac{9}{4}-\dfrac{9}{2}-3\\\\\\\therefore \boxed{ f(\frac{3}{4} )= -\frac{21}{4} }[/tex]

Thus, the vertex is (3/4, -21/4).

The standard form equation for the hyperbola is:

x^2/9 - y^2/16 = 1

To find the standard form equation for a hyperbola, we need to know the location of its center and the lengths of its axes.

The center of the hyperbola is simply the midpoint between the two vertices, which is (0,0).

The distance between the center and each vertex is 6 units, so the length of the transverse axis is 2a = 12, where a is the distance from the center to either vertex.

The slope of the asymptote is given by b/a, where b is the distance from the center to each focus. Since the hyperbola is symmetrical about the x-axis, we can assume that one focus is at (c, 0) and the other is at (-c, 0), where c is some positive number.

The slope of the asymptote is y/x = (4/3), so we have:

b/a = 4/3

c^2 = a^2 + b^2

Substituting b/a = 4/3 and a = 6/2 = 3, we get:

b = a * (4/3) = 4

c^2 = 3^2 + 4^2 = 25

c = 5

So the foci of the hyperbola are at (5, 0) and (-5, 0).

Therefore, the standard form equation for the hyperbola is:

(x - h)^2/a^2 - (y - k)^2/b^2 = 1

where (h,k) = (0,0), a = 3, and b = 4:

(x - 0)^2/3^2 - (y - 0)^2/4^2 = 1

Simplifying this equation gives:

x^2/9 - y^2/16 = 1

So the standard form equation for the hyperbola is:

x^2/9 - y^2/16 = 1

a) The average cost per appliance of producing the first 90 appliances is calculated below: The cost of producing x appliances is given by c(x) = 900 + 80x - 0.1x^2.

Therefore, the cost of producing the first 90 appliances is c(90) = 900 + 80(90) - 0.1(90)^2

= 900 + 7200 - 810

= 6390

Therefore, the average cost per appliance of producing the first 90 appliances is calculated as follows:

Average cost = total cost / number of appliances produced

= 6390 / 90

= $71 per appliance. Hence, the average cost per appliance of producing the first 90 appliances is $71 / appliance. b) The marginal cost when 90 appliances are produced can be calculated by computing the derivative of the given cost function c(x). Therefore, MC = c'(x)= d(c(x)) / dx

= 80 - 0.2x

The marginal cost when 90 appliances are produced is, therefore, MC(90) = 80 - 0.2(90)

= $62. Hence, the marginal cost when 90 appliances are produced is $62.c)

The cost of producing one more appliance after the first 90 have been made can be calculated as c(91) - c(90).

c(90) = 6390 (as calculated in part a above)c(91)

= 900 + 80(91) - 0.1(91)^2

= 6470.9

Therefore, the cost of producing one more appliance after the first 90 have been made is c(91) - c(90)= 6470.9 - 6390

= $80.9 (approx.) We can compare this cost with the marginal cost when 90 appliances are produced, which is $62. We observe that the marginal cost is less than the cost of producing one more appliance after the first 90 have been made. This means that the cost of production increases when we produce one more appliance after the first 90 appliances.

Answer:

x = -6 or x = 2

Step-by-step explanation:

Step 1:  Put the equation in standard form:

First, we need to subtract 8 from both sides to put the equation in the standard form of a quadratic, whose general equation is given by:

ax^2 + bx + c = 0

(x^2 + 4x - 4 = 8) - 8

x^2 + 4x - 12 = 0

Step 2:  Factor the equation:

In our equation, 1 is a, 4 is b, and -12 is c.  

Thus, we can factor the equation by finding two terms whose product is equal to a * c and whose sum equals 4.

We see that 2 * -6 = -12, which is the same as 1 * -12 = -12.  

Furthermore, 2 - 6 = 4.

To plug in 2 and -6 as a factor, we use the opposite sign of 2 and -6.

Thus, the factored form of the equation is:

(x - 2)(x + 6) = 0

Step 3:  Solve for x by setting each term equal to 0:

We can solve for x by setting (x + 2) and (x - 6) equal to 0:

Setting (x - 2) equal to 0:

(x - 2 = 0) + 2

x = 2

Thus, one solution for x is x = 2.

Setting (x + 6) equal to 0:

(x + 6 = 0) - 6

x = -6

Thus, the other solution for x is x = -6.

Thus, our solutions are x = 2 and x = -6.

Optional Step 4:  Check validity of solutions:

We can check that our answers for x are correct by plugging in 2 and -6 for x in the original equation and seeing if we get 8:

Checking x = 2:

(2)^2 + 4(2) - 4 = 8

4 + 8 - 4 = 8

12 - 4 = 8

8 = 8

Checking x = -6:

(-6)^2 + 4(-6) - 4 = 8

36 - 24 - 4 = 8

12 - 4 = 8

8 = 8

Thus, our answers for x are correct.

The filled van has a height of 4 feet, indicating the vertical dimension from the floor to the top of the crates inside.

To determine the height of the van that is filled with crates, we need to consider the volume of the crates and the total volume of the van.

Given that each crate has a volume of one cubic foot, and there are 30 crates covering the floor of the van, the total volume occupied by these crates is 30 cubic feet.

Now, to find the remaining volume inside the van, we subtract the volume of the crates from the total volume of the van. The van has a volume of 150 cubic feet, and we have already accounted for 30 cubic feet occupied by the crates.

Remaining volume inside the van = Total volume of the van - Volume occupied by the crates

Remaining volume = 150 cubic feet - 30 cubic feet

Remaining volume = 120 cubic feet

Since the van is shaped like a rectangular prism, the height of the van represents the vertical dimension.

To find the height of the van, we divide the remaining volume by the area of the van's base. The base area can be found by dividing the remaining volume by the length and width of the van.

Given that the van is completely filled with crates, the base area is equal to the area of 30 crates.

Base area = Volume occupied by the crates / Height

Base area = 30 cubic feet / Height

a. The maximum number of electrons that can have the quantum numbers n=3 and l=1 in an atom is 6.

The principal quantum number (n) represents the energy level of an electron. In this case, n=3 means that the electron is in the third energy level.
The azimuthal quantum number (l) represents the shape of the orbital. For l=1, the orbital shape is a p orbital.
In a p orbital, there are three possible orientations, each represented by a different magnetic quantum number (m_l). These orientations are m_l=-1, 0, and 1.
For each orientation, there can be a maximum of 2 electrons, one with a spin of +1/2 and the other with a spin of -1/2.
Since there is only one orientation with m_l=1 for l=1, the maximum number of electrons is 2 for that specific combination of n and l.

Since there are three possible orientations for p orbitals, the maximum number of electrons for n=3 and l=1 is 3*2=6.

b. The maximum number of electrons that can have the quantum numbers n=5, l=3, and m_l=-1 in an atom is 2.

For n=5, the electron is in the fifth energy level.
For l=3, the orbital shape is a f orbital.
For f orbitals, there are seven possible orientations, each represented by a different m_l value: -3, -2, -1, 0, 1, 2, and 3.
For each orientation, there can be a maximum of 2 electrons, one with a spin of +1/2 and the other with a spin of -1/2.

Since there is only one orientation with m_l=-1 for l=3, the maximum number of electrons is 2 for that specific combination of n, l, and m_l.

c. The maximum number of electrons that can have the quantum numbers n=3, l=2, and m_s=+1/2 in an atom is 2.

The spin quantum number (m_s) represents the spin state of an electron. It can be either +1/2 or -1/2.
For the given quantum numbers, n=3 represents the third energy level and l=2 represents a d orbital.
In a d orbital, there are five possible orientations, each represented by a different m_l value: -2, -1, 0, 1, and 2.
For each orientation, there can be a maximum of 2 electrons, one with a spin of +1/2 and the other with a spin of -1/2.

Since there is no specific limitation based on the spin state, the maximum number of electrons for the given combination of n, l, and m_s is 5*2=10. However, since the question specifies m_s=+1/2, we can only consider half of that maximum, resulting in a maximum of 2 electrons.

The equation sin(z + w) = sin(z) cos(w) + cos(z) sin(w) holds true for z and w belonging to the complex number set. We need to prove the equation sin(z + w) = sin(z) cos(w) + cos(z) sin(w) for complex numbers z and w.

We can start by expressing sin(z) and cos(z) in terms of their exponential forms:

sin(z) = (e^(iz) - e^(-iz)) / (2i)

cos(z) = (e^(iz) + e^(-iz)) / 2

Similarly, we can express sin(w) and cos(w) in terms of their exponential forms:

sin(w) = (e^(iw) - e^(-iw)) / (2i)

cos(w) = (e^(iw) + e^(-iw)) / 2

Now, let's expand the right-hand side of the equation sin(z) cos(w) + cos(z) sin(w):

sin(z) cos(w) + cos(z) sin(w)

= [(e^(iz) - e^(-iz)) / (2i)] * [(e^(iw) + e^(-iw)) / 2] + [(e^(iz) + e^(-iz)) / 2] * [(e^(iw) - e^(-iw)) / (2i)]

Expanding this expression further:

= [(e^(iz)e^(iw) - e^(iz)e^(-iw) - e^(-iz)e^(iw) + e^(-iz)e^(-iw)) / (4i)] + [(e^(iz)e^(iw) + e^(iz)e^(-iw) + e^(-iz)e^(iw) + e^(-iz)e^(-iw)) / 4]

Simplifying this expression:

= [e^(iz+iw) - e^(iz-iw) - e^(-iz+iw) + e^(-iz-iw)] / (4i) + [e^(iz+iw) + e^(iz-iw) + e^(-iz+iw) + e^(-iz-iw)] / 4

Combining like terms:

= [2e^(iz+iw) - 2e^(-iz-iw)] / (4i)

= [e^(iz+iw) - e^(-iz-iw)] / (2i)

= sin(z + w)

Hence, we have proved that sin(z + w) = sin(z) cos(w) + cos(z) sin(w) for complex numbers z and w.

The table that shows no correlation is the third table, counting from the tom.

A table will show no correlation if we can't find any rule that relates the changes in oe of the variables with the changes in the other variable.

First table:

As x increases, y decreases until the point (6, -3), then increases to (8, -2), then it decreases and so on.

Second table.

Like the first one, but with more variation, it first decreases, then it increases until (10, 0), it decreases again to (14, -1), then it increases again.

Third table.

It increases steadily until the last point, where there is a sudden change.

Fourth table:

As x increases, y decreases steadly.

While in table 1 and 2 we can't see a prior any relation, we can see a semi periodic behavior in the increases-decreases, and there are no jumps in values of y.

For the third table the behavior is more random, and we can see two jumps in the y-values, on from -4 to 6 (10 units in total) and other from 10 to -16.

So this is the correct option.

The slope of the tangent at the point (3, 3, 1) is -27/7. Therefore, the equation of the tangent is 27x + 7y = 90.

The given curve is x³/2 + y³/2 = 4. We have to find the equation of the tangent to this curve at the point (3, 3, 1).

Let y = f(x), then x³/2 + y³/2 = 4 becomes

f(x) = (4 - x³/2)³/2 = 2(8 - x³)³/2.

The slope of the tangent at the point (3, 3, 1) is the value of f'(3).

We know that the derivative of f(x) is given by

f'(x) = -3x²/2 (8 - x³)-1/2 and

f'(3) = -27/7.

Therefore, the slope of the tangent at (3, 3, 1) is -27/7.

Using the point-slope form of the equation of the line, we get the equation of the tangent as  :

y - 3 = (-27/7)(x - 3)

27x + 7y = 90

Therefore, the slope of the tangent at the point (3, 3, 1) is -27/7. Therefore, the equation of the tangent is 27x + 7y = 90.

Thus, the vector equation of the plane passing through the points P, Q, and R is -10x + 22y - z + 29 = 0.

The steps for finding the vector equation for the plane passing through the points P = (3, 0, -1),

Q = (-2, -2, 3), and

R = (7, 1, -4) are explained below;

Let the position vectors of P, Q, and R be a, b, and c respectively.

That is, a = [3, 0, -1],

b = [-2, -2, 3], and

c = [7, 1, -4].

To find the vector equation for the plane, we need to calculate the normal vector to the plane using cross product of two vectors in the plane.

Let PQ and PR be two vectors in the plane.

Then, PQ = b − a

= [-2 - 3, -2 - 0, 3 - (-1)]

= [-5, -2, 4]PR

= c − a = [7 - 3, 1 - 0, -4 - (-1)]

= [4, 1, -3]

The normal vector n to the plane can be found using the cross product of PQ and PR as:

n = PQ × PR

= [(-2) × (-3) − 4 × 1, (3) × (-2) − 4 × (-5), (-5) × 1 − (-2) × 4]

= [-10, 22, -1]

Therefore, the vector equation of the plane can be written as: n . (r − a) = 0

where r is the position vector of any point on the plane.

So the equation of the plane is-10(x - 3) + 22(y - 0) - 1(z + 1) = 0.

Expanding this we get-10x + 30 + 22y - z - 1

= 0.-10x + 22y - z + 29 = 0

The left side of the equation 4 sin(4x) = -8 sin(2x) can be rewritten as sin(2x) cos(2x).

To rewrite the left side of the equation, we can use the double angle formula for sine. The double angle formula states that sin(2x) = 2sin(x)cos(x).

Let's apply the double angle formula to sin(4x):

sin(4x) = 2sin(2x)cos(2x)

Now, we can substitute this value back into the original equation:

4(2sin(2x)cos(2x)) = -8sin(2x)

Simplifying further:

8sin(2x)cos(2x) = -8sin(2x)

Now, we can cancel out the common factor of -8sin(2x):

sin(2x)cos(2x) = -sin(2x)

This is the rewritten form of the left side of the given equation using sin(2x) and cos(2x).

The bacteria would take approximately 6.6 hours to triple in size, if it doubles its size every four hours.

A bacteria that doubles its size every four hours takes approximately 6.6 hours to triple in size. As an initial point, when a bacteria doubles its size, it increases by two. To find the number of times the bacteria size has doubled to triple, we will need to know the number of times it has doubled its size.

We can, therefore, obtain this by calculating the logarithm of the ratio of the final size to the initial size. Let's represent the initial size of the bacteria as X. The number of times it doubles its size as Y. When the bacteria triples in size, it will have grown by three times its initial size:

Final size = 3X

If the bacteria doubles its size every four hours, its growth rate is 2 per four hours. Therefore, we can represent its growth rate in terms of the number of times it doubles its size as follows:

Growth rate = 2 ^ Y.

This means that the bacteria doubles in size for every Y number of times, it will have grown by a factor of 2. Therefore, if it triples in size, it doubles its size twice and then grows by half its size of the initial size (1/2). Therefore, we can represent the final size of the bacteria as follows:

Final size = (2^2) (1/2) X

= 2X.

So, to find the number of times the bacteria has doubled its size, we can calculate the logarithm of the ratio of the final size to the initial size:

3X/X = 2^Y(3X/X)

= (2^Y)3

= 2^YY

= log base 2 of 3

≈ 1.585

Therefore, the number of hours required for the bacteria to triple in size is the number of times it doubles its size (1.585) multiplied by the number of hours required to double in size (4 hours):

= 1.585 * 4 hours

= 6.34 hours (rounded to the nearest tenth)

Therefore, the bacteria would take approximately 6.6 hours to triple in size if it doubles its size every four hours.
