19. A sky diver steps out of an airplane at 5000 feet. Use the formula S = -16t2 + 5000 to find how long it takes the sky diver to reach 4000 feet.

answer: it's a

step-by-step explanation:

ou would have 12 of each

whatvare the choices

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
