-16 divided by 4 equals -4
Answer: 64 feet.
Explanation:
Perimeter formula: 2l + 2w
Area formula: l•w
Length = 3w
Area = 192 ft
![^{2}](https://tex.z-dn.net/?f=%20%5E%7B2%7D%20)
192 = (3w) • w
192 = 3
![w^{2}](https://tex.z-dn.net/?f=%20w%5E%7B2%7D%20)
192 ÷ 3 = 3
![w^{2}](https://tex.z-dn.net/?f=%20w%5E%7B2%7D%20)
÷ 3
64 =
![\sqrt{64}](https://tex.z-dn.net/?f=%20%5Csqrt%7B64%7D%20)
=
![\sqrt{ w^{2} }](https://tex.z-dn.net/?f=%20%20%5Csqrt%7B%20w%5E%7B2%7D%20%7D%20)
8 = w
Width = 8
Length = 3(8) = 24
Perimeter = 2(24) + 2(8) = 64 feet.
You use a modification of the pythagorean theorem to find
pythagoreas c^2=a^2+b^2
the easy way is you use the equation
![d= \sqrt{(x1-x2)^2+(y1-y2)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28x1-x2%29%5E2%2B%28y1-y2%29%5E2%7D%20)
so input in format (x,y) then
(2,2)
(7,5)
x1=2
y1=2
x2=7
y2=5
![d= \sqrt{(2-7)^2+(2-5)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%282-7%29%5E2%2B%282-5%29%5E2%7D%20)
![d= \sqrt{(-4)^2+(-3)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28-4%29%5E2%2B%28-3%29%5E2%7D%20)
![d= \sqrt{16+9}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B16%2B9%7D%20)
![d= \sqrt{25}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B25%7D%20)
![d= 5](https://tex.z-dn.net/?f=d%3D%205%20)
the distance is 5 units

Coefficient of Performance
Answer: g(1) is 1.
Step-by-step explanation:
If we are solving for g of 1 then the first equation can't be used to solve for g of 1 because it only works in x is equal to -2.
The same way the second function will not work because x has to equal to -1.
But in the last function which is written as a polynomial it will work for this situation because x is not equal to -2 or -1 so apart from those numbers every number will work the same way 1 will work.
So plot 1 into the function and solve for it .
g(1) = 1^3 - 1^2 + 1
g(1)= 1 - 1 + 1
g(1)= 1
