A ball is thrown in the air from the top of a building. Its height, in meters above ground as a function of time, in seconds, is given by h(t) = - 4.9t2 + 27t + 19. How long does it take to reach maximum height? Round to
the nearest hundredth of a second.
seconds

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

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)

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
