Question

The electrical charge on a metal plate is given

by the function below, where t is the time in
seconds. What is the charge after 10 seconds?
C (t) = 12e +15

Answer 1

after 10 seconds the charge is 1.624

Explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one.

The electrical charge on a metal plate is given by the function below, where t is the time in seconds. What is the charge after 10 seconds?

C (t) = 12
`e^{(-t)/(5) }`

My answer:

Given the information:

C (t) = 12
`e^{(-t)/(5) }`

when t =10 we have:

C (10) = 12
`e^{(-10)/(5) }`

<=> C (10) = 12
`e^(-2)`

<=> C (10) = 12
`(1)/(e^(2) )`

<=> C (10) = 12 * 0.1353

<=> C (10) = 1.624

Hence, after 10 seconds the charge is 1.624
