You are hiking along the California coast and wonder about the height of a particular Giant Redwood tree. You are 5

yulyashka [42]

Answer:

172.5

Step-by-step explanation:

Use similar triangles and a proportion.

(tree height)/(tree shadow length) = (your height)/(your shadow length)

x/(270 ft)= (5 ft 9 in.)/(9 ft)

x/(270 ft)= (5 ft + 9/12 ft)/(9 ft)

x/(270 ft)= (5.75 ft)/(9 ft)

9x = 270 * 5.75 ft

x = 30 * 5.75 ft

x = 172.5 ft

The height, h, in feet of a piece of cloth tied to a waterwheel in relation to sea level as a function of time, t, in seconds ca

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.
