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.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
