Question

D(h)=5e^(-0.32)h
After 7 Hours there will be how many milligrams?

Answer 1

I am guessing h = e?
if so,
D(7) = 5(7)^(-0.32)
Solve for the exponent, then multiply.

Answer 2

I am sorry! the h is after the (-0.32)

Answer 3

Okay, D(7) = 5*e^(-.32)(7)

Answer 4

ok how would I get that answer to be 0. something?

Answer 5

What is e equal to?

Answer 6

I am getting 25.42

Answer 7

I think we can plug in e = 0
D(7) = 5*(0)^(-.32)(7)
D(7) = 5*(0)*(7)
D(7) = (0)*7
D(7) = 0
