For number one answer is 45 180-45-90=45 Number 2 answer is 80
180-50-50=80
For number three answer is 22
180-70-50=60 180-60-98=22
For number four the answer is 70
180-40-70=70
So 20% is 1/5 and 1/5 of 55 is 11. That means there are in total 11 blue candies if 1/5 of them is damaged then technically 2.2 of them are which is kinda weird as it doesn't give whole number
Answer:
120m3
Step-by-step explanation:
V=4/3 x π x r³
= 4/3 x 3.14 x 3.1³
≈ 120 (nearest tenth)
Given:
The function is
.
To find:
The function
.
Solution:
We have,
![f(x)=3(x+7)^{\frac{1}{4}}](https://tex.z-dn.net/?f=f%28x%29%3D3%28x%2B7%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D)
Substitute f(x)=y.
![y=3(x+7)^{\frac{1}{4}}](https://tex.z-dn.net/?f=y%3D3%28x%2B7%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D)
Interchange x and y.
![x=3(y+7)^{\frac{1}{4}}](https://tex.z-dn.net/?f=x%3D3%28y%2B7%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D)
Divide both sides by 3.
![\dfrac{x}{3}=(y+7)^{\frac{1}{4}}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B3%7D%3D%28y%2B7%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D)
Taking power 4 on both sides.
![\left(\dfrac{x}{3}\right)^4=y+7](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7Bx%7D%7B3%7D%5Cright%29%5E4%3Dy%2B7)
Subtract 7 from both sides.
![\left(\dfrac{x}{3}\right)^4-7=y](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7Bx%7D%7B3%7D%5Cright%29%5E4-7%3Dy)
![y=\left(\dfrac{x}{3}\right)^4-7](https://tex.z-dn.net/?f=y%3D%5Cleft%28%5Cdfrac%7Bx%7D%7B3%7D%5Cright%29%5E4-7)
Substitute
.
![f^{-1}(x)=\left(\dfrac{x}{3}\right)^4-7](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cleft%28%5Cdfrac%7Bx%7D%7B3%7D%5Cright%29%5E4-7)
Therefore, the correct option is C.
