Question

For the Function f(t) = Pe^rt , if P= 4 and r= 0.04, then what is the value of f(4) to the nearest tenth?

Answer 1

cough cough 4.7 just took it

Answer 2

Answer: 4.7

Explanation:

The given function:
`f(t) = Pe^rt`

If the value of P = 4 and r = 0.04, then to find f (4), we need to substitute t = 4 in the given function , we get

`f(4)=4e^(0.04*4)\\\\\Rightarrow\ f(4)=4e^(0.16)\\\\\Rightarrow\ f(4)=4*1.17351087099\\\\\Rightarrow\ f(4)=4.69404348397\approx4.7`

Hence, f(4)= 4.7
