Hi, Can you answer these questions for me? Thank you!

If you can just give me the answer making it simple that would help out a lot.

Question 1:

\fWhich one of the functions represents exponential decay? Of(r) = 6(;)* Of (r) = 0.9(5) Of() = () Of (x) = 2.6(1.01)2Which one of the functions represents exponential growth? Of () =() Of (x) = =(2.8)- Of (x) = 2.8(1.5) Of () =(4)\fAn investment of $75,000 increases at a rate of 12.5% each year. Let t represent the number of years and A(t) represent the amount after t years. Which function models this situation? O A (t) = 75000(12.5) O A (t) = 75000(0.875) O A (t) = 75000(1.125)* O A (t) = 75000(13.5)An investment of $75,000 increases at a rate of 12.5% each year. What will be the value of the investment after 30 years? Round to the nearest cent. A population of 752,000 people decreases at a rate of 1.4% each year. Let t represent the number of years and A(t) represent the amount after t years. Which function models this situation? O A (t) = 752000(-0.4) O A (t) = 752000(0.986) O A (t) = 752000(2.4) O A (t) = 752000(1.014) O A (t) = 752000(0.014)A population of 752,000 people decreases at a rate of 1.4% each year. To the nearest whole number. what will be the population after 18 years? A house has been losing 2% of its value over the past several years. The house was originally purchased for $250,000. Let t represent the number of years and A(t) represent the amount after t years. Which function models this situation? O A (t) = 250000(1.2)* O A (t) = 250000(1.02) O A (t) = 250000(0.8)* O A (t) = 250000(0.98) O A (t) = 250000(-.02)*A house has been losing 2% of its value over the past several years. The house was originally purchased for $250000. To the nearest dollar, how much should the house be worth 20 years after the initial purchase? A bacteria culture started with 200 bacteria and is growing by 40% each day. Let t represent the number of days and A(t) represent the amount after t days. Which function models the situation? O A (t) = 200(1.4) O A (t) = 200(1.04) O A (t) = 200(0.4) O A (t) = 200(0.96)* O A (t) = 200(40)A bacteria culture started with 200 bacteria and is growing by 40% each day. To the nearest whole number, how many bacteria will be in the culture after 10 days?The function A (t) = 4|:l00('|19'74)t models the exponential decayr of money in an account, where t represents the number of years and A[t) represents the amount in the account after t years. What percent is the account decreasing by per year
