Which is an exponential decay function? f(x) = 3/4(7/4)^x
f(x)=2/3(4/5)^-x
f(x) = 3/2(8/7)^-x
f(x) =1/3(-9/2)^x

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

answer: a

step-by-step explanation:

both equations and proportions are better.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
