Suppose you work for a sporting goods company, and you want to order shipping boxes for bike helmets. Each helmet is already pac

madreJ [45]

Answer: $n^2+6n-135=0$

Step-by-step explanation:

The length, width and height of the smaller box are n inches , n inches and 8 inches respectively,

And, According to the question,

The shipping boxes has 2 inches extra width than that of smaller box and 4 inches extra length than that of smaller box, Also, The height of the shipping box should be the same as the helmet box.

Thus, the Length of the shipping box = (n + 4) inches

Width = (n+2) inches and height = 8 inches

Thus, the volume of the shipping box,

$V = (n+4)\times (n+2)\times 8=(n^2+6n+8)8=8n^2+48n+64$

But, V = 1,144 cubic inches,

⇒ $8n^2+48n+64=1144$

⇒ $n^2+6n+8=143$

⇒ $n^2+6n-135=0$

Which is the required equation that models the volume of the shipping box.

Which of the following functions is graphed below

Gnoma [55]

Remark

A function is defined as 1 y value per x value. The y values can be the same for 2 x values, but the x values must have just 1 value associated with it. I am describing a vertical line test for a function. This is a function.

A 1 to 1 function means that the function obeys the horizontal line test. That means that for every x there is only 1 y value.

This graph is both a function and a 1 to 1 function. So the answer is A.

None of the other answers are this complete and one of them is wrong.

B is wrong. It is a 1 to 1 function.

C is wrong. The graph is a function.

D is wrong. No y values are duplicated.
