The side lengths to get an area of 40 could be 8 and 5

Area = length x width

So if one side is 8 and the other is 5 then it will have to be the same on the opposite side of the rectangle

Perimeter = side + side + side+ side

So it is 8+8+5+5 = 16+10 = 26 feet

This is just one answer, there is more than one correct answer for this problem

A possible perimeter for the rectangle would be 28

Area=L x W

40/10=4

Width=4, Length=10

Perimeter=L+L+W+W

4+4+10+10=28

Talia is packing a moving box. She has a​ square-framed poster with an area of 4 square feet. The​ cube-shaped box has a volume
nasty-shy [4]

The volume of a cube = e^3

e = a single edge of the cube.

Area of a square = a^2

a = a single side of the square.

The volume of our cube = 13 ft^3

e = \sqrt[3]{13} = 2.35 ft

The area of our square =  4 ft^2

a = \sqrt{4} = 2 ft

The edge of our cube is greater than the length of our square's side.

The poster will lie flat in the box.

PLEASE HELP CORRECT ANSWER ONLY (NOT D) 15 POINTS AND BRAINLIEST !!
Murrr4er [49]

Answer:

c Point E

Step-by-step explanation:

Remember coplanar means being on the same plane.

Look at each side/square as a plane. If we look closely, we can see that A, C, G, and E are on the same square/plane. E is coplanar.

Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
sineoko [7]

Answer:

An exponential function in the form y=9(4ˣ)

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that exponential function

                  y = a bˣ ...(i)

The equation (i) passes through the point (0,9)

               9 = a (b )⁰ = a

             a =9

<u><em>Step(ii):-</em></u>

The equation (i) passes through the point (3,576)

            576 = 9(b)³

         ⇒    \frac{576}{9} = b^{3}

      ⇒     64 = b³

     ⇒     4³ = b³

             (4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }

             b = 4

<u><em>Final answer:-</em></u>

An exponential function in the form y=abˣ

An exponential function in the form y=9(4ˣ)

<u><em></em></u>

<u><em>   </em></u>

Which equation shows a correct relation for triangle RSQ?
son4ous [18]

Answer:

sinQ=cosR

Step-by-step explanation:

First we need to find out the measure of ∠R.

The sum of all the angles in a triangle add up to 180. Therefore:

∠Q+∠R+∠S=180

66+∠R+90=180

∠R=180-156

∠R=24°

Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.

sinQ=cosR

sin66=cos24

0.9135454576=0.9135454576

So the second equation is the correct relation.
