<span> the total distance around the pie is the circumference of the pie, assuming that the pie is a perfect circle then the formula for the circumference of a circle is:
c = piD
where pi is equal to 3.1416
D is the diameter of pie or circle
substitute the given values
C = (3.1416) ( 20 ft
c = 62.832 ft

You basically plug in numbers..I will use positive integers.
You basically plug in numbers for x to find the y .
0,1
1,-2
2,-5
3,-8 and so on
Answer:
See explanation below
Step-by-step explanation:
<u>First we will solve the radical equation</u> (which I guess was problem 1),
Let's start by simplifying it:
![3\sqrt{6-x}+4=-8\\ 3\sqrt{6-x}=-8-4\\ 3\sqrt{6-x}=-12\\\sqrt{6-x}=-4](https://tex.z-dn.net/?f=3%5Csqrt%7B6-x%7D%2B4%3D-8%5C%5C%203%5Csqrt%7B6-x%7D%3D-8-4%5C%5C%203%5Csqrt%7B6-x%7D%3D-12%5C%5C%5Csqrt%7B6-x%7D%3D-4)
Now we will solve the equation by squaring both sides of the equation:
![\sqrt{6-x} =-4\\6-x=-4^{2} \\6-x=16\\-x=16-6\\-x=10\\x=-10](https://tex.z-dn.net/?f=%5Csqrt%7B6-x%7D%20%3D-4%5C%5C6-x%3D-4%5E%7B2%7D%20%5C%5C6-x%3D16%5C%5C-x%3D16-6%5C%5C-x%3D10%5C%5Cx%3D-10)
So the calculation for x was that x = -10
However, this does not produce a solution to the equation: When we plug this value into the radical equation we get:
![3\sqrt{6-x} +4= -8\\3\sqrt{6-(-10)} +4=-8\\3\sqrt{16}+4 = -8\\ 3(4)+4 = -8\\12 + 4 = -8](https://tex.z-dn.net/?f=3%5Csqrt%7B6-x%7D%20%2B4%3D%20-8%5C%5C3%5Csqrt%7B6-%28-10%29%7D%20%2B4%3D-8%5C%5C3%5Csqrt%7B16%7D%2B4%20%3D%20-8%5C%5C%203%284%29%2B4%20%3D%20-8%5C%5C12%20%2B%204%20%3D%20-8)
This happens because <u>when we first squared both sides of the equation in the first part of the problem we missed one value for x </u>(remember that all roots have 2 answers, a positive one and a negative one) while squares are always positive.
When we squared the root, we missed one value for x and that is why the calculation does not produce a solution to the equation.
Answer:
99cm^2
Step-by-step explanation:
When finding an area of a triangle, you multiply base times height and then divide by 2.
In this case,
Height:11
Base: 18
So then apply the formula:
![\frac{11*18}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B11%2A18%7D%7B2%7D)
Solve (using a calculator lol)
We get 99
Don't forget units!
So the final answer is 99cm^2
The answer is 8 To you question
