The rate of change means that the designer hourly charge is $55 per hour
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total cost of hiring the designer after x hours.
From the table, using the point (0, 125) and (15, 950):
The rate of change means that the designer hourly charge is $55 per hour

Answer: 18 degrees
Step-by-step explanation:
To get the mean add up all of the values that you are given and divided it by how many there are.
Week One:
The values added up to 364 I then divided 364 by 7 to get a mean value of 52.
Week Two:
The values added up to 490, I then divided 490 by 7 to get a mean value of 70.
(In the above problems, I divided by 7 because there are 7 temperatures given)
I then subtracted 70 and 52 and got 18 degrees greater during week two.
Please find the diagram in the attachment for a better understanding of the solution provided here.
We will use the Pythagoras' Theorem here. The right triangle is PQR. Because it is a right triangle, therefore, we can use the Pythagoras' Theorem here.
Thus, as required by you we have successfully proven that the value of PQ=16.7
