Answer:

f(g(x)) =  5x^{2}   + 10x+ 5

Step-by-step explanation:

Here, the given functions are:

f(x)  = 5x^2\\g(x) = x+1

Now, (fg)(x)  = f (g(x))

f(g(x))= f (x+1)

\implies f(x+1)  = 5(x+1)^2

By ALGEBRAIC IDENTITY:

(a+b)^2  = a^2 + b^2  + 2ab\implies (x+1)^2  = x^{2}  + 1 + 2x

So, 5(x+1)^2   = 5(x^{2}  + 2x + 1)  = 5x^{2}   + 10x+ 5

Hence, f(g(x)) =  5x^{2}   + 10x+ 5

sp2606 [1]
<h2>Answer:</h2>

Prediction for the number of unsuccessful rolls is 15.

<h2>Step-by-step explanation:</h2>

There is \frac{1}{6} chance of rolling number 6 on the cube. If we want to find out what is the prediction for rolling number 6 in 18 rolls, we need to multiply 6*\frac{1}{6} which is 3. So if we roll a cube 18 times, we will probably got number 6 three times. When we subtract 3 from 18 (18-3), we get 15. That is the answer to your question.

I hope I helped you. I will be really happy, If you mark my answer as the brainliest.Your David

F(x)=8_-4x-x^3. g(x)=x^2+7x-9. Find f(x)+g(x)
11111nata11111 [884]

(8 - 4x -  {x}^{3} ) + ( {x}^{2}  + 7x - 9) \\  =  -  {x}^{3}  +  {x}^{2}  - 4x + 7x + 8 - 9 \\  =  -  {x}^{3}  +  {x}^{2}  + 3x - 1
(8x - 4x -  {x}^{3} ) + ( {x}^{2}  + 7x - 9) \\  -  {x}^{3}  +  {x}^{2}  + 8x - 4x + 7x - 9 \\  -  {x}^{3}  +  {x}^{2}  + 11x - 9
The answer is either B, and you forgot to put in the ^2 in the answer choice, or C, and you forgot to put an x where there is a _ in the question.

Check the actual question (the one you recieved, not the one posted here) and see where the mistakes are. If f(x) = 8x - 4x - x^3, then your answer is C. However, if B is actually -x^3 + x^2 + 3x - 1, then the answer is B.
