Find the Avrage value of the function i=15(1e to the power of 1/2 t) from t=0 and t=4?
A.7.5 sqrt 1+4e^2 e^4 <<<<not sure though
B.7.5 sqrt 42e^2 + e^4
C.7.5 sqrt 4+4e^2  e^4
D.7.5 sqrt 52e^2 + e^4

I integrated the expression
15(1e^(t/2))
and got: 15(1e^(t/2)).
When evaluated from 0 to 4 I got:
30*%e^(2)+30
Divide by (40) gives 7.5(e^2+1)=8.5
Could there be a typo somewhere?
