Find the average value of the function i=15(1-e to the power of -1/2 t) from t=0 and t=4?

A.7.5(1+e^-2)<< my answer

B.7.5(2+e^-2)

C.7.5(2-e^-2)

D.7.5(3-e^-2)

Find the rms value of the function i=15(1-e to the power of -1/2 t) from t=0 and t=4?

A.7.5 sqrt 1+4e^-2 -e^-4 <<<<my answer?

B.7.5 sqrt 4-2e^-2 + e^-4

C.7.5 sqrt 4+4e^-2 - e^-4

D.7.5 sqrt 5-2e^-2 + e^-4

For the first part, A is correct.

(see my response at

)

For the second part, A is also correct.

7.5sqrt(1+4e^(-2)-e^(-4))
