Abullet is fired straight up from a bb gun with initial velocity 1120 ft./s at an initial height of 8 feet. use the formula h=-16t^2 +v0 t+8 to determine how many seconds it will take for the bullet to hit the ground. that is, when will h=0 ? round your answer to the nearest whole number

Bullet will hit the ground after 70 seconds.

Step-by-step explanation:

A bullet is fired straight up from a BB gun with initial velocity 1120 ft/s at an initial height of 8 ft.

We need to find time when bullet hit the ground.

As we know when bullet hit the ground height would be 0

So, we set h=0 and solve for t .

Using quadratic formula

Thus, Bullet will hit the ground after 70 seconds.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
