<u><em>Part 1:</em></u><u>Before we begin, you need to remember the following rule:</u>
<u>The given expression is:</u>
Since the base is the same in both numerator and denominator, we can apply the above rule. <u>This means that:</u>
= 12¹⁻³ = 12⁻²
<u><em>Part 2:</em></u><u>Before we begin, you need to remember the following rule:</u>
x⁻ᵃ =
Now, <u>from part 1</u>, we simplified the expression into 12⁻²
Since the power is negative, we can apply the above rule.
<u>This means that:</u>
12⁻² =
Hope this helps :)
Answer:
Step-by-step explanation:
We can use the Pythagorean Theorem:
The two legs are x and (x + 14) and the hypotenuse is (x + 16). Therefore:
Expand:
Combine like terms:
Subtract the right from the left:
Subtract:
Factor:
Zero Product Property:
Solve:
The x cannot be negative since a side cannot measure -4. So, our only answer is:
So, the legs are 10 and 24 with the hypotenuse being 26.
9.5 divided into 12 get you the amount of miles per minute
then multiplying that answer by 60 to get the hours gets you the final answer
so 9.5/12 then X 60 = 47.5 miles/hour
No because a circle has an infinite number of lines of symmetry.
Choice (A) has zero slope becsuse her cost doesn't depend on the number of visits.
