The value of the variable m in the rectangle is given as follows:

m = 12.5.

The segments from the rectangle, and their lengths, are given as follows:

They are opposite vertices of the rectangle, as they do not have any common vertex.

Since they are opposite vertex, it doesn't matter if these segments are bases, heights or diagonals, they will have the same length.

Thus the numeric value of variable m is obtained as follows:

WY = XZ

(as they have the same length).

Replacing the measures of each of these segments:

12m + 7 = 16m - 43

12m - 16m = -43 -7

-4m = -50

4m = 50 (multiplication by -1).

m = 50/4

m = 12.5.

The sales tax is $1.2  and the total cost of the item is  $21.2   .

In the question,

it is given that ,

the selling price of the item is $20.

the rate of sales tax is = 6^ ,

so the sales tax can be calculated using the formula

sales tax = 6% of selling price

So , sales tax = 6% of 20

= 0.06 * 20

= 1.2

so , the sales tax is $1.2

the total cost of the item will be = selling price + sales tax

= 20 + 1.2

= 21.2

Therefore , The sales tax is $1.2  and the total cost of the item is  $21.2   .

Answer:

  P'(-16, 0)

Step-by-step explanation:

You want the coordinates of the image of P(-4, 0) when the figure is dilated by a factor of 4 about the origin.

Dilation about the origin multiplies each coordinate by the dilation factor:

  P' = 4P

  P' = 4(-4, 0) = (-16, 0)

The coordinate of the image point are (-16, 0).

The statement of Gabriella, “The graph will not have an inverse function.” is incorrect. Option B is correct.

Let us understand about the given graph:

The given graph is a graph of a cube root function.

So, the statement of Noelle, “The graph represents the function [tex]f(x)=\sqrt[3]{x}[/tex]." is correct.

So, option A is not correct.

The inverse of a cube root function is a cubic function.

So, the statement of Gabriella, “The graph will not have an inverse function.” is incorrect.

So, option B is correct.

The domain and range of the cube root function are all real numbers.

So, the statement of Julian, “The domain and range of the function is all real numbers.” is correct.

So, option C is not correct.

From the graph, we can see f(-1) = -1.

The correct response variable is the amount of pain relief.

Given that,

A tall glass of ice water, according to some, can help migraine sufferers find relief. Multiple migraine sufferers will be recruited by researchers to participate in a test. The individual will either take a placebo pill or a common painkiller when they get a migraine. Additionally, only half of each group will take the pill with water; the other half will sip on a small amount of water. The quantity of pain relief is then reported by participants.

To find :  What is the response variable in this experiment.

Explanation :

Response variable or study variable, in general called as dependent variable  is the variable of main focus in study. We want to study the changes in explanatory or independent variables are associated with response variable. Sometimes we want to measure the effect of predictors i.e explanatory variables on response variable.

For example in hand, we want to determine whether the drinking ice water is associated with amount of pain relief. Hence in this study, response variable is the amount of pain relief.

Step-by-step explanation:

4x-c=k  

solve for x

use the reverse order for the usual order of operations, to solve for x

first use addition

4x = k+c

then use division

x = (k+c) / 4

The point (-2, 6) is reflected across the y-axis then the new coordinates of the point are (2, 6).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

We know when a point (x, y) is reflected along the y-axis (x, y) becomes

(- x, y).

Given, A point (-2, 6) is reflected across the y-axis.

Answer:

Part A: C

Part B: T shirt = $20, hat = $12

Step-by-step explanation:

Part A:

He buy 8 T-Shirts and 5 hats for $220.

He buy another buys 5 T-shirts and 1 hat for $112.

assuming t = tshirt, h = hat, C is the correct answer

Part B:

8t + 5h = 220

5t + h = 112

1. Use second equation to represent h in term of t

h = 112 -5t

2. Replace h in first equation with h from 1.

8t + 5(112 -5t) = 220

8t + 560 - 25t = 220

-17t + 560 = 220

-17t = 220 - 560

-17t = -340

t = -340/-17 = 20

3. Replace t in equation from 1. with t from 2.

h = 112 -5(20) = 112 - 100 = 12

Option C is correct which is dC/dt = π (dd/dt).

According to the question,

We know that the diameter of the circle is half the radius of the circle.

d = r/2

By transferring r to the left-hand side and d to the right-hand side

r = d/2

We also know that circumference of the circle is

C=2πr

C=2πd/2

C=πd

Now we will differentiate on both the side with respect to t and we will get,

dC/dt = π (dd/dt)

Differentiation is a technique for tracking down the subordinate of a capability. Differentiation is a process, where we find the momentary rate of change in capability in light of one of its variables. We usually differentiate with respect to time which is represented as ds/dt.
