Answer:
C.
Step-by-step explanation:
Since the radius of the circle is 12 units, we can calculate the circumference.
2 * pi * r = 2 * pi * 12 = 24 * pi = 24pi.
The arc angle is 240 degrees, and the whole circle would be 360 degrees. So, we can set up an equation.
1 * x = 4 * 4 * pi
x = 16pi
So, your answer is C.

Answer: B. binomial.
Step-by-step explanation:
1. You can classify polynomials based on the number of terms the polynomial has:
- If it has one term is classified as a monomial.
- If it has two term is classified as a binomial.
- If it has three terms is classified as a trinomial.
2. The polynomial has two terms. Therefore, the correct clasification is: binomial.
3. Then, the correct answer is the option B.
Answer:
The best fit is <em>A. Linear model</em>
<em></em>
Step-by-step explanation:
Given:
Monthly Rate = $20, Number of customers = 5000
If there is a decrease of $1 in the monthly rate, the number of customers increase by 500.
To find:
The type of model that best fits the given situation?
Solution:
Monthly Rate = $20, Number of customers = 5000
Let us decrease the monthly rate by $1.
Monthly Rate = $20 - $1 = $19, Number of customers = 5000 + 500 = 5500
Let us decrease the monthly rate by $1 more.
Monthly Rate = $19 - $1 = $18, Number of customers = 5500 + 500 = 6000
Here, we can see that there is a <em>linear change </em> in the number of customers whenever there is decrease in the monthly rate.
We have 2 pair of values here,
x = 20, y = 5000
x = 19, y = 5500
Let us write the equation in slope intercept form:
Slope of a function:
So, the equation is:
Putting x = 20, y = 5000:
Let us check whether (18, 6000) satisfies it.
Putting x = 18:
so, it is true.
So, the answer is:
The best fit is <em>A. Linear model</em>
