4: $1800

5: $3000

Step-by-step explanation:

1: 10%*12000 = 1200

2: Food 50%*12000 = 6000

3: 25%*12000 = 3000

4: 15%*12000 = 1800

For a recent year, the rate of first-class postage is as follows:

Law Incorporation [45]

Answer:

$0.95

Step-by-step explanation:

Given that weight of the function = x

Given that cost of the postage for mail having weight less than or equal to 1 oz = $0.44

then to find the equation can be written as

C(x)=0.44 where 0<x<=1

Similarly we can write equation for other parts

C(x)=0.61 where 1<x<=2

C(x)=0.78 where 2<x<=3

C(x)=0.95 where 3<x<=3.5

Now we can write them together as piecewise function as shown in below:

$C(x)=\left\{\begin{matrix}0.44 & 0$

to graph that we just draw horizontal lines for each as none equation contains x on the right side .

3.48 oz is less that 3.5 so we will use $0.95.

If t=38.5 and s=31.4 find S. Round to the nearest tenth

zubka84 [21]

<u>Answer:</u>

The correct answer option is C. S = 54.6°.

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

We are given a right angled triangle with two known sides, $s$ and $t$ .

We are to find the value of the angle $S$ .

For that, we will use sine.

$sin S = \frac { s } { t }$

$sin S = \frac { 3 1 . 4 } { 3 8 . 5 }$

$S = sin'0.815$

S = 54.6°

What is the length of the major axis of the ellipse (x-7)^2/4+(y+3)^2/16=1

yuradex [85]

$\bf \begin{array}{llll}
\cfrac{(x-{{ h}})^2}{{{ a}}^2}+\cfrac{(y-{{ k}})^2}{{{ b}}^2}=1\\\\ \cfrac{(x-{{ h}})^2}{{{ b}}^2}+\cfrac{(y-{{ k}})^2}{{{ a}}^2}=1
\end{array}\quad 
\begin{cases}
\textit{major axis}=a+a\\
a=\textit{the larger denominator}\\
b=\textit{smaller denominator}
\end{cases}\\\\
-----------------------------\\\\
\cfrac{(x-7)^2}{4}+\cfrac{(y+3)^2}{16}=1\implies \cfrac{(x-7)^2}{2^2}+\cfrac{(y+3)^2}{4^2}=1\quad 
\begin{cases}
a=4\\
b=2
\end{cases}$
