The return height, in feet, of a bouncing regulation basketball can be modeled using the exponential equation f ( x ) = 5(0.85) x . Jonas tried to explain the function rule and said, “When the ball is dropped from an initial height of 5 feet, the ball bounce height each time will always be 0.85 times 5 feet.” Which of the following explains where Jonas’ answer is incorrect.

step-by-step explanation:

jml angle lkj & angle mj = lm

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
