7. the height of an object x seconds after it is kicked in the air is modeled by the expression -16 + 8t. how long does it take the object to hit the ground?

2 seconds

Step-by-step explanation:

The height of the object is modeled by the expression -16 + 8t.

It means we have

Now, when the object hits the ground, the height must be zero.

Hence, substitute h = 0 in the above equation

Therefore, it will take 2 seconds to hit the ground.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
