Find the average rate of change for each situation below. Give appropriate units in your answers, and show all of your work,
1. The cost for a seamstress to make p purses is found using the function C(p)= 15p +250. Find and interpret the rate of
change from x = 0 to x = 15.
2. The function (y) = 15,000(0.85)' gives the value of a far t years after it was manufactured
oa. What is the average rate of change, and what does it mean in this situation from t=0 to t=5?
b. What does the average rate of change mean in this situation from t = 5 to t = 10?
3. To find the average cost per T-shirt for producing x T-shirts, a company uses the function c(x)=
10x + 300
What is the
Х
average rate of change from x = 10 to x = 20?

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
