The expression 87000(1.12)^t represents the population of a town t hears after 1996. By what percent does the population increase each year? Pls help i need it

Answers

Answer:

12%

Step-by-step explanation:

Percentage increase of something is often represented in a formula of a format like this:

X=Ar^t

Where X represents the total amount after t years.

A or 87000 in this case represents the starting value, which is this case is the starting population of the town. r or 1.12 represents the percentage increase, if it increases by 12% than the next year has 1.12 times as many people as the previous year so this is represented by 1.12 rather than say 0.12 which would indicate a 88% decrease instead. t is the time, no. of years in this case, that has elapsed since 1996.

This formula basically means that a town population of 87000 increases by 12% for every year of time that elapses.

Hope this helped!

The answer to the question is 12%

Answers

Answer:

a. after 10 times 10

b. after 9 times 9

Step-by-step explanation:

Answer:

1. it goes : 1,2,4,5,10,20,25,50,100. so it is reversed once it gets to 10(which is multiplied by itself)

2. it goes: 1,3,9,27,81. since it is a square number it is only multiplied by 9 once before repetition.

3. a square number like 36 has the same concept as the 81, so when it gets to 6 × 6 it begins the reversion.

4. a non sqaure number like 28 goes 1,2,3,4,7,19,28. so it's right after the 4×7 it begins the reversion.

5. for example,3 goes 1,3 so I believe there is no need for repetition since there is only one pair of numbers as factors.

At the beginning of the season, Jamie pays full price for a ticket to see Panters, her favorite baseball team. The Panthers currently have 33 wins and 31 losses. A. Represent the total change in the cost of a ticket given in their losses. B. What is the cost of a ticket for the next game they play?

Answers

Answer:

The answer is B i think

Step-by-step explanation:

Answer:

a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:

Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71

b) The cost of a ticket for the next game given they have 31 losses is:

Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93
