ok well first off if you look at this logically. earth has gravity. what comes up will eventually come down, so given that look for equations where the a is negative.

Answer 3

that should take out the first and second option

Answer 4

If the help is really good, the fan and medal is usually a given (:

Answer 5

now, your "ball" is being thrown from a height of 20 ft making 20 your y-intercept. so, what has 20 as the y-intercept?

Answer 6

that should leave you with the answer D

Answer 7

The general equation is \[\Large s(t)=–16t^2 + v0t + h0\]
where v0 represents the initial velocity of the object and h0 represents the initial height of the object

Answer 8

That's -16 btw and then you just have to plug in the 32 and 20 in the respective places that they gave you
