<h2>Hello!</h2>

The answer is: a. 40

<h2>Why?</h2>

We are working with composite functions, so, to find the correct option, first we need to follow the composite function process:

(h\circ g)=h(g(x))

So,

We are given the functions:

g(x)=2x\\\\h(x)=x^{2}+4

So,

(h\circ g)(x)=(2x)^{2}+4

Then, evaluating with "x" equal to -3, we have:

(h\circ g)(-3)=(2*-3)^{2}+4=(-6)^{2}+4=36+4=40

So, the correct option is a. 40

Have a nice day!

Answer:

a. 40

Step-by-step explanation:

Given

g(x)=2x and h(x)=x^2+4

(h\circ g)(x)=h(g(x))

(h\circ g)(x)=h(2x)

We plug in 2x into  h(x)=x^2+4.

(h\circ g)(x)=(2x)^2+4

(h\circ g)(x)=4x^2+4

We now substitute x=-3.

(h\circ g)(-3)=4(-3)^2+4

(h\circ g)(-3)=36+4=40

The correct choice is A.

Marianna [84]

Answer:

Average score per game = 60,000 per game

Step-by-step explanation:

Given:

Points scored in first game = 25,000

Points scored in second game = 125,000

Points scored in third game = 30,000

Find:

Average score per game

Computation:

Average = Sum of observation / Number of observation

So,

Sum of all game = 25,000 + 125,000 + 30,000

Sum of all game = 180,000

Number of games = 3

Average score per game = 180,000 / 3

Average score per game = 60,000 per game

What is the length of CO?
posledela

Answer:

Pythagorean theorem, eh?

Step-by-step explanation:

The way to do this is use the radius-tangent angle theorem thing...

It states that, a radius that intersects a point of tangency(I think that's what it's called) is perpendicular to the tangent. Thus, CW is perpendicular to OW!

Thus, it forms a right triangle, where we can use Pythagorean Theorem!

If you don't know what it is, check the internet! It's pretty simple.

CW^2+OW^2=OC^2\\144+81=OC^2\\225=OC^2\\OC=15

So, there you go! Hope this helps!

NOTE: This answer was recently deleted for violating community guidelines, so I just re-uploaded it!(and edited it) So if you do need more help, do some research!
