Question

The electrical charge on a metal plate is given

Answer 1

Answer:

after 10 seconds  the charge  is 1.624

Step-by-step 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$e^{\frac{-t}{5} }$

My answer:

Given the information:

C (t) = 12$e^{\frac{-t}{5} }$  

when t =10 we have:

C (10) = 12$e^{\frac{-10}{5} }$

<=>  C (10) = 12$e^{-2}$

<=>  C (10) = 12$\frac{1}{e^{2} }$

<=> C (10) = 12 * 0.1353

<=>  C (10) = 1.624

Hence, after 10 seconds  the charge  is 1.624
