Answer:

\boxed{\sf \ C \ is \ the \ correct \ answer \ ! \ }

Step-by-step explanation:

fog(x)=f(g(x))

so it comes

f(g(x))=f(x+1)=4(x+1)^2

<u>so C is the correct answer</u>

Answer:

Option B

Step-by-step explanation:

f(x) = 4x^2\\g(x) = x+1

Multiplying both will give us:

(fg)(x) = 4x^2(x+1)

=> (fg)(x) = 4x^3+4x^2

If a(x) = 2x - 4 and b(x) = x + 2, which of the following expressions produces a quadratic function
Rina8888 [55]

Answer:

Step-by-step explanation:

Multiplying a(x) and b(x) together results in a quadratic equation (a trinomial).  This trinomial looks like (a·b)(x) = (2)(x - 2)(x + 2).  Note that this is a "special product;"  (2)(x^2 - 4); there is no middle term.

Mr. Wilson invested money in two accounts. His total investment was $20,000. If one account pays 5% in interest and the other pa
blagie [28]

a = amount invested at 5%

b = amount invested at 2%

now, we know the total invested by Mr Wilson was 20000, so whatever "a" and "b" might be, we know that a + b = 20000.

a + b = 20000\implies b = 20000-a \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{5\% of a}}{\left( \cfrac{5}{100} \right)a}\implies 0.05a~\hfill \stackrel{\textit{2\% of b}}{\left( \cfrac{2}{100} \right)a}\implies \begin{array}{llll} 0.02b\\\\ \stackrel{substituting}{0.02(20000-a)} \end{array}

now, we know the total of earned interest is 550 bucks, so then

0.05a~~ + ~~0.02(20000-a)~~ = ~~550\implies 0.05a+400-0.02a=550 \\\\\\ 0.03a+400=550\implies 0.03a=150\implies a=\cfrac{150}{0.03}\implies a=5000 \\\\\\ ~\hspace{24em}\stackrel{20000~~ - ~~5000}{b=15000}
