4. exercise 3, section 5.7. use iteration to guess an explicit formula for the recursive sequence below and then prove your answer using mathematical induction. ak=k*ak-1, for k> =1 and a0=1.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

89

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
