The body of a 154 pound person contains approximately 4 × 10-1 milligrams of gold and 16 × 101 milligrams of aluminum. Based on
Eddi Din [679]

The number of milligrams of aluminum is 400 times the number of milligrams of gold in the body.

<u><em>Explanation</em></u>

Lets assume, the number of milligrams of aluminum is x times the number of milligrams of gold in the body.

The body of a 154 pound person contains approximately 4 × 10⁻¹ milligrams of gold and 16 × 10¹ milligrams of aluminum.

So the equation will be...

(4*10^-^1)*x= 16*10^1\\ \\ x= \frac{16*10^1}{4*10^-^1}= 4*10^2=400

So, the number of milligrams of aluminum is 400 times the number of milligrams of gold in the body.

Find the inverse of the following function.
Margarita [4]
Let f(x) be y.

y  = x³ + 3

Switch x and y:

x = y³ + 3

Now you need to isolate y and you would get inverse function.

x - 3 = y³

∛(x-3) = y

Final answer: f ⁻¹(x) = ∛(x-3)

Hope this helps.
