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.

Find the value of x<br> .<br><br> 12.5,−10,−7.5,x<br> ; The mean is 11.5<br> .
fomenos
There are four values, including the unknown value x. The sum of the four values is the given value of the mean, 11.5, multiplied by four. Let S be the sum of the four values. Then we can write:
S=11.5\times4=46

46=12.5 + (-10)+(-7.5)+x
x = 46 + 5 = 51
The answer is: The value of x is 51.

Answer: 23.4 ft^3

Step-by-step explanation: The perimeter of the base is 10.7, it is a square so the 4 sides of the base are equal. One side of the base is equal to 2.675 if the perimeter (4 sides) is equal to 10.7, so plug that and the height into the formula for the volume of a square pyramid to get 23.38, or 23.4 to the nearest tenth.
