The ball is dropped from a building and the quadratic function which models the ball`s height is:
h ( t ) = - 16.1 t² + 150
We can find the initial height if we calculate h ( 0 ), or the height for : t = 0 sec.
h ( 0 ) = -16.1 · 0² + 150 = 0 + 150 = 150 ft
Answer:
The ball was dropped from 150 feet.
It helps if you have an example, like f(x) = 2x+3
What you typically do, is:
- draw xy axis, label them (ie., 1,2,3,4 along both axes)
- calculate the f(x) values for several x (e.g., -2, 0, 1, 3, doesn't matter).
- plot the calculated values as points. The calculated f(x) is your y value.
- sketch a smooth line through the points. It helps if you know in advance if the line is going to be straight or curved.
- The more points you calculate, the more accurate your graph will be

3 - 9 I think that's the answer I'm not too sure because you didn't provide me your answer but hope this helps .

In this case, we must use trigonometry to find the value of x:
Thus the value of x rounded to the nearest tenth is <u>8.2</u>

Hope that helps!
