![f^{-1}(x)=\dfrac{\sqrt[3]{x}+1}{2}}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B%5Csqrt%5B3%5D%7Bx%7D%2B1%7D%7B2%7D%7D)
Step-by-step explanation:
Interchange x and y in the function definition and solve for y.
![x=(2y-1)^3\\\\\sqrt[3]{x}=2y-1\qquad\text{take cube root}\\\\\sqrt[3]{x}+1=2y\qquad\text{add 1}\\\\y=\dfrac{\sqrt[3]{x}+1}{2}\qquad\text{divide by 2}\\\\\boxed{f^{-1}(x)=\dfrac{\sqrt[3]{x}+1}{2}}](https://tex.z-dn.net/?f=x%3D%282y-1%29%5E3%5C%5C%5C%5C%5Csqrt%5B3%5D%7Bx%7D%3D2y-1%5Cqquad%5Ctext%7Btake%20cube%20root%7D%5C%5C%5C%5C%5Csqrt%5B3%5D%7Bx%7D%2B1%3D2y%5Cqquad%5Ctext%7Badd%201%7D%5C%5C%5C%5Cy%3D%5Cdfrac%7B%5Csqrt%5B3%5D%7Bx%7D%2B1%7D%7B2%7D%5Cqquad%5Ctext%7Bdivide%20by%202%7D%5C%5C%5C%5C%5Cboxed%7Bf%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B%5Csqrt%5B3%5D%7Bx%7D%2B1%7D%7B2%7D%7D)
Answer:
That's a bit hard. Hope you can solve it!
Answer:1:10 is the ratio
Step-by-step explanation:if 7 are red then there are only 70 green left so there are 7 red to every 70 green or reduced is 1:10
(0.9)* (1.5+5.8)
First, Add the values to the right. You get (0.9) * (7.3)
Multiply 9 and 73 to get 730 -73, which is 700-43, 660 - 3, which is 657.
Divide by 100 by moving the decimal point to get 6.57 as your final answer.
Hope that helped!
