when solving this, do i take it out of the parenthesis or make it into a square root? because its very confusing.
Licemer1 [7]

Finding the inverse function:

We are given a function y = f(x). To find the inverse function, we exchange x with y in the original function, and then isolate y.

So

We are given the function:

f(x)=(x+7)^5

So

y=(x+7)^5

Changing x with y

x=(y+7_{})^5

Now, we have to isolate y. So

(y+7)^5=x

We can apply the fifth root to both sides. So:

\sqrt[5]{(y+7)^5}=\sqrt[5]{x}y+7=\sqrt[5]{x}f^{-1}(x)=y=\sqrt[5]{x}-7

Sylvanite is a mineral that contains 28.0% gold by mass. Determine how much sylvanite would you need to dig up to obtain 81.0 g
lidiya [134]
Since Sylvanite only contains 28% gold by mass, then to obtain 81.0 grams of gold, x amounts of sylvanite must be mined. To determine x, we divide 81 grams by 28%. This equation is shown below:

0.28X = 81

X = 81/0.28
X = 289.29 grams

Therefore, 289.29 grams of sylvanite must be dug up to obtain 81 grams of gold.
