a ball was thrown with an initial upward velocity of 80 feet per second from an initial height of 4 feet. write an equation for h, the height of the ball in feet, t seconds after it was thrown.

80x^ + 4t + t

Yah I think that’s the answer

S=ut +0.5gt^2

s+4=80t -.5*9.81t^2

I believe

Using the equation of motion, you add 4 because it’s already at a height of 4, it’s negative gravity because it’s going against gravity.

S=80t-0.5gt^2 -4 final answer

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
