I think it’s even because if you flip one of them they will equal up on the same line. it’s basically the inverse of the other one so it’s even
Answer:
4pi + 8 km
Step-by-step explanation:
the circumference of teh circle is d*pi = 8pi. since this is a semicircle the circumference is 4pi. then the perimeter is 4pi + 8
Answer:

b. Line segment PT and Line segment ST
c. PSQRU
d. Lines PR and SQ
e. Plane C and Plane QRS
Step-by-step explanation:
Given:
The function is:
![f(x)=\sqrt{7x-21}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%7B7x-21%7D)
To find:
The steps of finding the inverse function
.
Solution:
We have,
![f(x)=\sqrt{7x-21}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%7B7x-21%7D)
The steps of finding the inverse function are:
Step 1: Substitute
.
![y=\sqrt{7x-21}](https://tex.z-dn.net/?f=y%3D%5Csqrt%7B7x-21%7D)
Step 2: Interchange x and y.
![x=\sqrt{7y-21}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B7y-21%7D)
Step 3: Taking square on both sides, we get
![x^2=7y-21](https://tex.z-dn.net/?f=x%5E2%3D7y-21)
Step 4: Adding 21 on both sides, we get
![x^2+21=7y](https://tex.z-dn.net/?f=x%5E2%2B21%3D7y)
Step 5: Divide both sides by 7.
![\dfrac{1}{7}x^2+3=y](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B7%7Dx%5E2%2B3%3Dy)
Step 6: Substitute
.
, where
.
Therefore, the inverse of the given function is
and the arrangement of steps is shown above.
