\begin{gathered} \text{Given} \\ g(x)=2x \\ h(x)=x^2+4 \end{gathered}

Solve for (g o h)(x)

\begin{gathered} (g\circ f)(x)=g\big(f(x)\big) \\ (g\circ f)(x)=g(x^2+4) \\ (g\circ f)(x)=2(x^2+4) \\ (g\circ f)(x)=2x^2+8 \end{gathered}

Next substitute x = 0

\begin{gathered} (g\circ f)(x)=2x^2+8 \\ (g\circ f)(0)=2(0)^2+8 \\ (g\circ f)(0)=8 \end{gathered}\text{Therefore, }(g\circ f)(0)=8

A box of stuffing costs $1.99 for 16 oz. Find the unit cost, round to the nearest hundredth.
Misha Larkins [42]

The given ratio is:

\frac{\text{ \$1.99}}{16oz}

To find the unit cost per ounce, we can use proportions as follows:

\frac{\text{ \$1.99}}{16oz}=\frac{x}{1oz}

Now, solve for x:

\begin{gathered} x=\frac{1oz\cdot\text{ \$1.99}}{16oz} \\ x=0.12 \end{gathered}

The cost per ounce (unit cost) is then $0.12/oz

DENIUS [597]

Answer: 26

Step-by-step explanation:

10 : 3 means for every 3 songs he kept, he deleted 10

He deleted 20

10 * 2 = 20

3 * 2 = 6

He deleted 20 songs, and kept 6.

So, he had 26 songs on his MP3 player.

20 + 6 = 26
