A skateboarder leaves a 12-foot tall ramp with an initial vertical velocity of 8 feet per sen
taurus [48]

To answer this, we substitute 12 ft to the f(h) in the given equation,   
f(h) = -8t² + 8t + 12 = 12

Subtracting 12 from both sides of the equation will give us an answer of,

-8t² + 8t = 0

Then, we transpose 8 to the other side and divide the equation by -8 and t, we get an answer of t = 1 second.

A meter stick casts a shadow 2.4 m long at the same time a flagpole casts a shadow 9.7 m long. How tall is the flagpole
Luda [366]
The first thing we are going to do is draw a diagram of the situation to help us to solve the situation.
We an draw tow similar triangle between the length of the shadows and the height of the stick and the pole.
Since <span>meter stick has a length of 1 meter, the height of our smaller triangle is 1 meter. Let </span>h be height of of the pole. Since both triangles are similiar we can establish a proportion between their corresponding sides and solve for h:
\frac{h}{1} = \frac{9.7}{2.4}
h=\frac{9.7}{2.4}
h=4.04

We can conclude that the pole is 4.04 meters tall.
