Abullet is fired straight up from a bb gun with initial velocity 1,120 feet per second at an initial height of 8 feet. use the formula h=−16t2+v0t+8 to determine how many seconds it will take for the bullet to hit the ground. that is, when will h=0

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. Using the value of velocity the equation becomes:

h(t)= -16t² + 1120t + 8

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 .

0 = -16t² + 1120t + 8

Using quadratic formula:

Since negative value of the time is not possible, we conclude that the bullet will hit the ground after 70 seconds.

its 4 because 2 times 2 is 4, if you double the number two you get four

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
