The length of a rectangle is 14 meters. If the perimeter of the rectangle is 44 meters, what is the width?

1 answer:

8 0

In a rectangle the opposite sides are equal. So if the perimeter is 44 meaning all sides added up equal 44. Then you can subtract 14 twice because there are two 14 length sides. That will result in 16. Then divide by 2 because there are two side lengths that are the widths. This results in 8. The correct answer is A. 8m

Answer:

422.39

Step-by-step explanation:

circle area with

π r²

π*12*12 = 452.389342117

Minus area of the rectangle

452.389342117 - 3 * 10

= 422.389342117

rounded to the nearest hundredth:

422.39

PLEASE HELP URENT What is the length of leg s of the triangle below?

n200080 [17]

Answer:

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 45 = s / 4 sqrt(2)

Multiply each side by 4 sqrt(2)

4 sqrt(2) *sin 45 = s

4 sqrt(2) * 1/ sqrt(2) =s

Using calculus, you can find a function’s maximum or minimum by differentiating and setting the result to zero. Do this for equa

Elenna [48]

Answer:

$\dfrac{dx}{d\theta}=\dfrac{2v_0^2\cos2\theta}{g}$

$x=\dfrac{v_0^2}{g}$ at $\theta=45$

Step-by-step explanation:

$x=\dfrac{v_0^2\sin2\theta}{g}$

Differentiating with respect to $\theta$ means $v_0$ and $g$ are constants. So we differentiate only the $\sin2\theta$ term.

Assume $y=\sin2\theta$ .

Let $u=2\theta$ .

$\dfrac{du}{d\theta}=2$

Also, $y$ becomes

$y=\sin u$

$\dfrac{dy}{du}=\cos u$

By chain rule,

$\dfrac{dy}{d\theta}=\dfrac{dy}{du}\cdot \dfrac{du}{d\theta}$

$\dfrac{dy}{d\theta}=\cos u\cdot2=2\cos u=2\cos 2\theta$

Adding back the constants,

$\dfrac{dx}{d\theta} = \dfrac{2v_0^2\cos2\theta}{g}$

Equating this to 0,

$\dfrac{dx}{d\theta}=\dfrac{2v_0^2\cos2\theta}{g}=0$

$\cos2\theta=0$

$2\theta = \cos^{-1}0=90$

$\theta=45$

Using this value of $\theta$ in the expression for $x$ ,

$x=\dfrac{v_0^2\sin(2\times145)}{g}=\dfrac{v_0^2\sin90}{g}=\dfrac{v_0^2}{g}$ (since $\sin90=1$ )

2m + 14 = -3?I need the steps and answer

Inessa [10]

2m+14=-3
First, subtract 14 from both sides to make the problem simplifer.
2m+14-14=-3-14
2m=-17
Divide both sides by 2 to solve the problem.
2m/2=-17/2
m=8.5
Hope it helps. :D

Question 8

Stells [14]

The mean of the data is: 67.1

The median is: 70.5

The mode is: 71

<h3>What is the Mean, Median, and Mode of a Data Set?</h3>

The mean = average
Mode = data point that appears the most
Median = center of the data.

Given, 68, 79, 71, 52, 71, 54, 71, 81, 54, 70:

Mean = (68 + 79 + 71 + 52 + 71 + 54 + 71 + 81 + 54 + 70)/10

Mean = 671/10

Mean = 67.1

Median = (70 + 71)/2 = 70.5

Mode = 71
