BartSMP [9]

Answer:

20 seconds

Step-by-step explanation:

I assume you mean $h(t)=8\cos(\frac{\pi}{10}t)$ for your function.

As the given function is in the form of $f(t)=a\cos(bt+c)+d$ (some textbooks may write this formula differently), the period is equal to $\frac{2\pi}{|b|}$ . Hence, the period of the given function is $\frac{2\pi}{|\frac{\pi}{10}|}=\frac{2\pi}{1}*\frac{10}{\pi}=\frac{20\pi}{\pi}=20$ , or 20 seconds.
