Question

PLEASE PLEASE PLEASE HELP ME I WILL GIVE BRAINLEIST

1. Summerfield HS has student elections every year. Lately the school has seen a 5% decrease in voting from election to election. If 490 students voted this year how many are expected to vote 7 years from now? Round to the nearest student.


2. What is the average rate of change of the function on the interval from x = 0 to x = 5?

f(x)=1/2(3)^x

Enter your answer, as a decimal, in the box.

Answer 1

Answer:

Problem 1: 342

Problem 2:20.2

Step-by-step explanation:

Remark

Problem 1

A 5% reduction means that if you start with a hundred % and take 5% away from it, you get 100/100 - 5/100 = 95 /100.

If you reduce the 95/100 you get 0.95 in decimal form.

So the equation for voting a production of 7 years from now is projected to be

V = 490 * 0.95^7

0.95^7 = 0.69833

V = 490 * 69833

V = 342.2 to one decimal place. which represents the number of people that will vote 7 years from now.

Problem 2

The way this should be done is change / interval

f(0) = 1/2 * (3)^0

f(0) = 1/2 * 1

f(0) = 1/2

f(5) = 1/2 * 3^5

f(5) = 1/2 * 243

f(5) = 121.5

Average = (121.5 - 1/2) / (6 - 0)

Average = 20.167 I don't know how you are supposed to round this. I would say that the answer is 20.2
