Answer:

Step-by-step explanation:

28/4 is the radius of the half circle which is 7

if the whole thing was a rectangle the area would be

28 * 24 = 672

area of a half circle is A = pi * r^2/2

pi is also 22/7

A = 22/7 * 7^2/2 -> 22/7 * 49/2 -> 77

2 half circles' area is 77*2 = 154

672 - 154 = 518

The functions f and g are defined as follows.

Troyanec [42]

Answer:

f(-5)= 90, g(7)= -3x+4

Step-by-step explanation:

First Solve f(x)

f(x)= 3×^2-3x

Plug in -5 to the x

3(5)^2-3(-5)

f(x)= 90

Then Solve g(x)

g(x)=-3x+4

Plug in the 7 in the x

g(x)=-3x+4

g(x)=17

2/3=n/12<br><br> solve the proportion

Natali [406]

Answer: $n=8$

<u>Cross-multiply</u>

<u></u> $2/3=n/12$ <u></u>

<u></u> $(2)*(12)=n*(3)$ <u></u>

<u></u> $24=3n$ <u></u>

<u></u>

<u>Flip the equation</u>

<u></u> $24=3n---->3n=24$ <u></u>

<u></u>

<u>Divide both sides by 3</u>

<u></u> $3n/3=24/3$ <u></u>

<u></u> $24/3=8----> n=8$ <u></u>
