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[tex]e^{\frac{-t}{5} }[/tex]
My answer:
Given the information:
C (t) = 12[tex]e^{\frac{-t}{5} }[/tex]
when t =10 we have:
C (10) = 12[tex]e^{\frac{-10}{5} }[/tex]
<=> C (10) = 12[tex]e^{-2}[/tex]
<=> C (10) = 12[tex]\frac{1}{e^{2} }[/tex]
<=> C (10) = 12 * 0.1353
<=> C (10) = 1.624
Hence, after 10 seconds the charge is 1.624
