Answer:

$\frac{1}{3}$

Step-by-step explanation:

Using the rule of exponents/ radicals

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$

$a^{\frac{1}{2} }$ ⇔ $\sqrt{a}$

Given

$9^{-\frac{1}{2} }$

= $\frac{1}{9^{\frac{1}{2} } }$

= $\frac{1}{\sqrt{9} }$

= $\frac{1}{3}$

Find the inverse of the following function.

Naddik [55]

For this case we must find the inverse of the following function:

$f (x) = 8 \sqrt {x}$

For this, we follow the steps below:

We change f (x) to y:

$y = 8 \sqrt {x}$

We exchange the variables:

$x = 8 \sqrt {y}$

We solve for y:

$8 \sqrt {y} = x$

We divide between 8 on both sides of the equation:

$\sqrt {y} = \frac {x} {8}$

We raise both sides of the equation to the square to remove the root:

$y = (\frac {x} {8}) ^ 2\\y = \frac {x ^ 2} {64}$

So, the inverse is: $f ^ {- 1} (x) = \frac {x ^ 2} {64}$

What is The sum of the cost of dinner d and a $12 tip divided equally between 3 people?

TEA [102]

So, if you're trying to ask what 12 divided by 3 is, then the answer is four. (Using inverse operation), because 4x3=12. But, make sure you put the label! The answer is $4.
