2 answers:
Answer:
Step-by-step explanation:
Given:
We need to find the inverse of given function.
If is a function then inverse [/tex] x=f^{-1}(x)[/tex]
Inverse function is symmetry about the line y=x
Step 1: switch x and y
Step 2: solve for y
divide both sides by 3
Inverse function:
Hence, The inverse function is

To solve for the other leg, you need to use Pythagorean theory.
The theory states that C^2 = A^2 + B^2
In your case, you have to solve for B.
C = 40 (hypotenuse) A = 24 (leg 1)
The formula rewritten for B is
Now, you can solve.
Therefore, B = 32.
So the second leg is 32 feet.

This is equal to:
When you add a negative number, it turns into subtraction.
First, I would change it to mixed numbers:
Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:
Now, you simply subtract:
10-9=1
1/4 is your answer.

Given parameters:
Percentage gain = 300%
Selling cost last year = $2420
Unknown:
Selling cost this year = ?
Solution:
To solve this problem;
Profit percent =
300 =
3 =
S- 2420 = 7260
S = $9680
To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
