24=3y-6 => 30=3y, y=10,

12 = 5x+2 => 10=5x, x =2

Basically parallel sides must have the same length (parallelogram)

Hope it helps!

The 13-foot string is arranged into a rectangle. Let L denote the length of the rectangle,

soldi70 [24.7K]

The expressions for the width, W, and area, A, of the rectangle in terms of L are:

W = $\frac{13}{2}$ - L
A = $\frac{13L - L^{2} }{2}$

The expression for the perimeter of a rectangle is given as:

P = 2(L + W)

where L is its length and W its width

a. Given that the perimeter of the rectangle is 13 feet, then;

13 = 2(L + W)

divide through by 2

$\frac{13}{2}$ = L + W

So that;

W = $\frac{13}{2}$ - L

The required formula for the width as a function of L is: W = $\frac{13}{2}$ - L

b. Area of a rectangle can be expressed as;

A = L * W

substitute the expression for width in that of area to have

A = L * ( $\frac{13}{2}$ - L)

= $\frac{13}{2}$ L - $L^{2}$

A = $\frac{13L - L^{2} }{2}$

The expression for the area A is: A = $\frac{13L - L^{2} }{2}$

1140 was rounded to the nearest ten.<br>What is the upper bound?<br>

zloy xaker [14]

Answer:

1145

Step-by-step explanation:

<em>The upper bound is the smallest value that would round up to the next estimated value</em>.

Since the number was rounded to nearest ten, the upper bound is:

1145

which rounds up to 1150 which is the next estimated value greater than 1140

United States facing a budget deficit of 1.5 billion, population was 3.9 million how much would each person have to contribute t

Diano4ka-milaya [45]

Answer:

Each person would have to contribute to contribute $385 to pay a 1.5 deficit.

Step-by-step explanation:

To determine:

How much would each person have to contribute to pay a 1.5 deficit if United States facing a budget deficit of 1.5 billion and 3.9 million population?

Fetching Information and Solution Steps:

United States facing a budget deficit of 1.5 billion
Population = 3.9 million

We have to determine how much would each person have to contribute to pay a 1.5 deficit.

Just dividing 1500 millions (1.5 billion) by 3.9 million as:

$\frac{1500}{3.9} =384.6153$

which is rounded to $385.

Therefore, each person would have to contribute to contribute $385 to pay a 1.5 deficit.

Please help with this precalc!!! i desperately need help

Paladinen [302]

Step-by-step explanation:

4 is the A or Ampltiude

To find the period set it equal to 2 pi/B

$\frac{2\pi}{b} = \frac{6}{1}$

$\frac{b}{2\pi} = \frac{1}{6}$

$\frac{2\pi}{6}$

$\frac{\pi}{3}$

There is no phase shift

The midline or d or vertical shift is 1.

Our equation for 8 is

$4 \sin( \frac{\pi}{6} x) + 1$

9.Use sin function. The a value is 2 or -2 your choice.

Set up the period equal to the equation

$\frac{2\pi}{b} = \frac{\pi}{3}$

$\frac{b}{2\pi} = \frac{3}{\pi}$

$b = \frac{3}{\pi} \times 2\pi$

Which equal 6.

B=6

There is no C and the D and Vertical Shift is 1.

Our equation is

$2 \sin(6x) + 1$
