Answer: 
Step-by-step explanation:
Here the function that shows the total area of mulch,

Also, the function that shows the total cost mulch that requires,

By putting the value of m,
We get,

Where x is the radius of the circle.
Thus, First option is correct.
Answer:
a. 1/27
Step-by-step explanation:
When dividing exponents and the base is the same, we subtract them
x^a/ x^b = x^(a-b)
3^3/3^6
3^(3-6)
3^(-3)
The negative exponent means it is in the denominator
1/3^3
1/27
4 × 1 × 3 = 12
2 × 1 × 3 = 6
12 + 6 = 18 cubic ft
<u>ANSWER</u>=<u>5.2</u>
<u />
<u>EXPLANATION</u>
This triangle shows a example of the Pythagorean Theorem, which means the equation is gonna be
a^2+b^2=c^2
The variables <u>a </u>and <u>b </u>are the straight sides of the triangle, while the variable <u>c </u> is the curved side on the triangle, or what we are trying to find in this question.
Firstly let’s take the two sides that already have a number shown, also known in the Pythagorean Theorem as sides <u>a </u>and <u>b</u>.
2^2+4.8^2=c^2
Now we want to square the two given numbers to get the equation
4+23.04=c^2
Now we add the two given numbers that we have now squared to get the equation
27.04=c^2
The final step will now be to take the number (27.04) and square root it, which should give you the answer, <u>5.2</u>
