7.675 inches of rain was the total amount in the two weeks
Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
Answer:
We use the power rule of exponents to find out that both sides of the equation equal 3^20 (or 3486784401).
Step-by-step explanation:
For this example, we can just use a calculator and find out that both (3^5)^4 and (3^4)^5 are the same value. But how do we know this algebraically?
When dealing with exponents, we must have a good understanding of the properties of exponents before doing any calculations.
For this example, I recognize that the power rule of exponents is being used:

So let's apply this rule to the given equation.
(3^5)^4 = (3^4)^5
3^(5*4) = 3^(4*5)
3^20 = 3^20
Now we know both sides of the equation equal 3^20 (or 3486784401).
Answer:
4.25%
Step-by-step explanation:
<u>Step 1: Calculate the commission paid</u>
<em>Commission = Gross earning - base salary</em>
<em>Commission = 441.3 - 375</em>
Commission = 66.3
<u>Step 2: Calculate the commission sales</u>
<em>Commission sales = Total sales - quota sales</em>
<em>Commission sales = 6560 - 5000</em>
Commission sales = 1560
<u>Step 3: Calculate the rate of commission</u>
<em>x% of 1560 = 66.3</em>
<em>x% * 1560 = 66.3</em>
<em>x% = 0.0425</em>
x = 4.25%
Therefore, the rate of commission was 4.25%.
