Answer:

C. 72°

Step-by-step explanation:

A circle has 360°. The circle, in this case, represents 70 people. So, 360° is equivalent to 70 people. Ranch represents 14 people and this has an equivalence in angles. The proportion can be written as follows

360°/x = 70/14

Solving for x gives

x = 360°*14/70 = 72°

If an object is dropped from a height of 144 feet, the function h(t)=-16t^2+144 gives the height of the object after t seconds.

shtirl [24]

Answer:

A. 3s

Step-by-step explanation:

The height of the object after t seconds is given by:

$h(t) = -16t^2 + 144$

When will the object hit the ground?

It hits the ground after t seconds, and t is found when $h(t) = 0$ . So

$h(t) = -16t^2 + 144$

$0 = -16t^2 + 144$

$16t^2 = 144$

$t^2 = \frac{144}{16}$

$t^2 = 9$

$t = \sqrt{9}$

$t = 3$

3 seconds, so the correct answer is given by option a.
