Answer:

Step-by-step explanation:
Given


See attachment for farm
Required
The cost of fencing the farm
First, calculate the radius of the farm.
The radius is represented with AC.
So, we have:
---- distance formula
So, we have:





Hence:
--- radius
Calculate the circumference of the circle



If 1 yard costs $30, 31.4 yards will cost:


Answer:
if you Simplify the expression it is 112x
(or 120-8x if 30x 24 is multiplication)
It would be 13 + 10t because she starts with 13 dollar charge in the first hour but every hour after that would be 10 dollars an hour.
Eight hundred seventy six thousand five hundred forty three.
Answer:
The answer is: y = 3x - 7
Step-by-step explanation:
Given point: (5, 8).
Slope m = 3
Use the point slope form and solve for y:
y - y1 = m(x - x1)
y - 8 = 3(x - 5)
y - 8 = 3x - 15
y = 3x - 15 + 8
y = 3x - 7
Proof:
f(x) = 3x - 7
f(5) = 3(5) - 7
= 15 - 7 = 8, giving (5, 8)
