Question
The power P in an electrical circuit varies with the time t according to the relationship P = 1 - (1,18^kt), where k is a constant.
After 43 s, the power is 0.83 W. Determine the power P after 60 s. Round off your answer to three value digits.

1 - 1.8^(43k) = 0.83
k = -0.07
So now plug in t=60
k = -0.07
So now plug in t=60

Wouldn't k be 0.17?
