Answer:

d

Step-by-step explanation:

If x represents the slant height, the graph would be a straight line.

If x represents the radius, the graph would be a parabola.

Looking at the answers, we're looking for x to be the slant height, so we're looking for a straight line.

We are looking for g(x). Answers a and b are wrong.

In g(x) r is fixed to 5 (this is given). So the slant height in the smallest possible cone would still be at least 5.

So the domain is x > 5.

d is your answer.

We have this formula for the surface area of a cone

SA = pi*r*s + pi*r^2

The pi*r^2 portion is the flat bottom part of the cone, which is a circle of radius r. The pi*r*s portion is the lateral surface area. This is the triangular part of the cone, so to speak.

-----------------

"one of the functions represents the surface area of a cone with radius 5 and slant height x". So we can say r = 5 and s = x to go from this

SA = pi*r*s + pi*r^2

to this

SA = pi*5*x + pi*5^2

SA = 5pi*x + 25pi

y = 5pi*x + 25pi

note how this is a linear function in the form y = mx+b

-----------------

"The other function represents the surface area of a cone with slant height 5 and radius x", meaning s = 5 and r = x

SA = pi*r*s + pi*r^2

SA = pi*x*5 + pi*x^2

SA = 5pi*x + pi*x^2

SA = pi*x^2 + 5pi*x

y = pi*x^2 + 5pi*x

This is a quadratic function due to the x^2 term. This graphs out a parabola.

-----------------

The graph given to us has f(x) as the parabola (it's the bowl shaped graph) while g(x) is the straight line

Therefore,

f(x) = pi*x^2 + 5pi*x

g(x) = 5pi*x + 25pi

f(x) is the cone with radius x and slant height 5

g(x) is the cone with radius 5 and slant height x

-----------------

Keep in mind that the slant height of a cone forms the hypotenuse of a right triangle when you do a vertical cross section. If the radius is 5, then the leg of the triangle is 5. The hypotenuse is always longer than either leg, so the hypotenuse x must be larger than 5. A right triangle would not be possible with the hypotenuse x < 5 (you would have to shrink the radius).

<h3>Answer: Choice D) The function g(x) models the surface area of a cone with radius 5, a slant height of x, and has a domain of x > 5</h3>

you have only nicole's and dimes in your piggy bank. when you ran the coins through a change counter, it indicated you have 595
Kryger [21]
Let's say the amount of nickels you have is hmm "n"

and the amount of dimes you have is "d"

there are 5cents in one nickel, so, if "n" is the total amount of nickels you have, that means 5 * n cents or 5n

there are 10cents in one dime, so, if "d" is the total amount of dimes  you have, that means 10*d or 10d

whatever 5n and 10d are, we know that their sum is 595
since the total amount the counter said you have is, only 595 cents

thus 5n + 10d = 595

solve for either, "d" or "n", and graph that

what are three likely combinations? well, just pick three points off that graph
