The given graph is for a piecewise function consisting of two intervals:
(1) x ≤ 1 ⇒⇒⇒ the graph in this interval like <u>a cubic </u>function.
(2) x > 1 ⇒⇒⇒ the graph in this interval like <u>a quadratic </u>function
By comparing to the given options
<u>The answer is option c.</u>
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:


The answers are:
P(9, 2) = 72
P(5, 5) = 120
P(7, 7) = 5040
These are examples of permutations. The problems are asking us to find the total number of ways an event can happen.
In the first case, P(9, 2), we are asked to find the ways that 2 things can be chosen out of a group of 9.
9 x 8 = 72
P(5, 5) = 5 x 4 x 3 x 2 x 1
P(7, 7) = 7 x 6 x 5 x 4 x 3 x 2 x 1
The square root of Pi is approximately 1.77245.
