Answer:
![f^{-1}(x)=\sqrt[3]{x-7}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7Bx-7%7D)
Step-by-step explanation:
First let me list the steps to find the inverse of a function.
1) Replace f(x) with y
2) Swap the locations of x's and y's
3) Solve for y
4) Replace y with 
Now lets do this with this function
![f(x)=x^3+7\\\\y=x^3+7\\\\x=y^3+7\\\\y^3=x-7\\\\y=\sqrt[3]{x-7}\\\\f^{-1}(x)=\sqrt[3]{x-7}](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E3%2B7%5C%5C%5C%5Cy%3Dx%5E3%2B7%5C%5C%5C%5Cx%3Dy%5E3%2B7%5C%5C%5C%5Cy%5E3%3Dx-7%5C%5C%5C%5Cy%3D%5Csqrt%5B3%5D%7Bx-7%7D%5C%5C%5C%5Cf%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7Bx-7%7D)

Answer:
6.2 =x
Step-by-step explanation:
cos 70 =x/18
Multiply each side by 18
18cos 70 =x/18 *18
18cos 70 =x
6.15636258 = x
To the nearest tenth
6.2 =x
This means that X in the equation equals -1
