Question

What’s the answer to this problem please and thank you

Answer 1

1.8574 hours

Explanation:

Solve for t.

Take the natural log of both sides.

`3000 = 75000e^(-1.733t)`

`1 = 25e^(-1.733t)`

`(1)/(25) = e^(-1.733t)`

`\ln (1)/(25) = \ln (e^(-1.733t))`

`-3.218875 = -1.733t`

`t = 1.8574`
