32 feet. Since the radius is 4 feet, the diameter would be 8 feet, and the diameter is also the perimeter of one side of the wood paneling. Add up all of those together and you get 32 feet!

The real numbers $x$ and $y$ are such that \begin{align*} x + y &= 4, \\ x^2 + y^2 &= 22, \\ x^4 &= y^4 - 176 \sqrt{
tamaranim1 [39]

You get everything you need from factoring the last expression:

x^4-y^4=-176\sqrt7

The left side is a difference of squares, and we get another difference of squares upon factoring. We end up with

x^4-y^4=(x^2-y^2)(x^2+y^2)=(x-y)(x+y)(x^2+y^2)

Plug in everything you know and solve for x-y:

-176\sqrt7=(x-y)\cdot4\cdot22\implies x-y=\boxed{-2\sqrt7}

Answer: 32.35 cm^2

Step by step:

Find the area of the rectangle first.

A= L • W
A= 11 • 4.2
A= 46.2 cm^2

Then find the area of the circle. The formula is A= pi (r)^2. The diameter of the circle is 4.2 cm because looking at the width of the rectangle it fits into the circle as well.

Half of the diameter is 2.1 cm which is the radius.

A= pi (r)^2
A= pi (2.1)^2
A= pi (4.41)
A= 13.85 cm^2

Then you would subtract 13.85 from 46.2 to find the shaded portion.

Hope this helps :))

What is the solution to the equation below log5(2x-3)=2
Komok [63]

Answer:

Step-by-step explanation:

Use the exponential form of this log equation. Rewriting this into exponential form gives us

5^2=2x-3

5-squared is 25, so

25 = 2x - 3 and

22 = 2x so

x = 11

What is T in -5t-2(5t+10)=100​
Alina [70]

Answer:

t=-8

Step-by-step explanation:

-5t-2(5t+10t)=100

-2 x 5t=-10t

-2 x 10 = -20

-5t-10t-20=100

combine terms and add 20

-15t=120

divide by -15

t=-8
