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.

look a the sides they are perpendicular

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
