16. In a volleyball match, Jenny serves the volleyball at 14 m/s, from a height of 2.5 m

above the court. The height of the ball in

h = -4.91 + 14t + 2.5, where h is the

height, in metres, and t is the time, in

seconds, after she serves the ball.

flight can be estimated using the equation

a) What is the maximum height of the

volleyball above the court? When does

this occur? Round answers to the

nearest tenth.

b) If a player on the other team contacts

the ball at a height of 0.5 m above the

court, how long does it take for the ball

to reach her? Round to the nearest

second.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
