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.

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

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
