34 & 36

Question 34

f(240) = 1.5e^(240/2)

f(240) = 1.95627. . .x 10^(52)

f(240) = 1.956

Question 36

f(20) = 250e^(0.05•20)

f(20) = 679.570

Yes? No?

Question 34

answer is f(240) = 1.95627×10^52 not f(240) = 1.956

when you get 1.95627. . .x 10^(52) as an answer, .... means there is more decimal places in 1.95627 , then multiply by x 10^(52)

Question 36 is correct
