Answer 1

Just plug in each value in to the formula. Will already showed you how to do 2. Just copy him, but use different numbers.

Answer 2

I hope you try to do this one. If you don't learn how to do it, you will get confused later on.

Answer 3

1st we need to find k
2600 = 2000e^k4
Solve for k
e^4K = 1.3
K4 = in (1.3)
K = 0.06559106612
Now substitute that in the exponential form
And solve when t= 17
P = 2000e^0.06559106612*17
P=6099.4

To the nearest whole number would be 6099
