Explain why the terms of the polynomial y2 + 7 are said to be relatively prime.
Georgia [21]

Answer:

The correct answer is because the alternative terms are prime and composite.

Step-by-step explanation:

The given polynomial is y^{2} + 7.

The value of the polynomial when y = 0 is 7.

The value of the polynomial when y = 1 is 8.

The value of the polynomial when y = 2 is 11.

The value of the polynomial when y = 3 is 16.

The value of the polynomial when y = 4 is 23.

The value of the polynomial when y = 5 is 32.

The value of the polynomial when y = 6 is 43.

And so on. Thus the value of the polynomial at alternate values of y are prime.  Thus this is why the polynomial is said to be relatively prime.

A building contractor estimates that her profit in dollars for a tall building will be given by the function:
IRINA_888 [86]

Answer:

The height is 20

The max profit is 1600

Step-by-step explanation:

P (h) = -4h^2 + 160h

The vertex is at

-b/2a = -160/2(-4) = 160/8 = 20

The height that will give the maximum profit is 20

We want to find the value at 20

P(40)  =-4(20)^2 +160(20)

          =-1600+3200

             1600
