A golf ball is hit from an elevated ground after 2 seconds, the golf ball reaches a maxium height of 20 feet and lands on the goround at 6 seconds. If the path of the ball is modled by a parabolic path. Determine the equation of the relationship bettewn the height of the golf ball and the time

answer:      

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
