Answer:

B)  f(x) =  -16(x - 1.5)² + 40

Step-by-step explanation:

The equation we have is: h(t) = -16x² + 48x + 4

The answers are all in vertex form, so we need to covert this equation into vertex form by completing the square.

Step 1:  factor out -16 from the first 2 terms...

-16(x² - 3x) + 4    

Step 2:  complete the square on this term...

-16(x² - 3x + (3/2)² - (3/2)²)

    -16(x² - 3x + (3/2)²) + 4 + 16(3/2)²

        -16(x - 3/2)² + 4 + 16(9/4)

             -16(x - 1.5)² + 4 + 4(9)

                   -16(x - 1.5)² + 40

So f(x) =  -16(x - 1.5)² + 40

Colt1911 [192]

Answer:

C. 6×11/6

Step-by-step explanation:

Because 11/6 is greater than 1, if you were to multiply it by 6, you would get a product greater than 6.

U guys are mean and never answer my questions, like i paid for no one to answer my question
Sav [38]

Answer:

Step-by-step explanation:

You have no grounds for making a statement like that.  There are a variety of reasons why you might not get immediate answers.  Be patient.

I will do the second part of this question (finding the first three numbers):

a(4) = a(3)*(-3) + 2 = -148, so a(3)*(-3) = -150 and a(3) = -50

a(3) = 50

a(2) = a(3)*(-3) + 2 = 50, so -3*a(3) = 48 and a(d) = -16

a(1) = a(2)*(-3) + 2 = -16, so a(2)*(-3) = -18 and a(1) = 6

The procedure for finding a(5), a(6) and a(7) is exactly the same.
