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.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.

prime

the number 37 is prime

answer: chelsea has 55 brushes

step-by-step explanation:

5 x 11 = 55

5 + 55 = 60
