X = (50 cos 30°)t, y = 4 + (50 sin 30°)t - 12t2; t = 9

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

sweetheart, there isn't a cube below.
