What is the polynomial function from the graph
Answers
Step-by-step explanation:
According to the graph, the function has
5 roots ⇒ x = - 3, - 2, - 1, 1, 3The function is decreasing so the leading term has negative coefficient.One of the local maximums is approximately (2, 6)The y-intercept is (0, - 1.5)The coefficient is going to be:
- 1.5 / (3*2*3) = - 1.5/18 = - 1/12One possible option is:
f(x) = - 1/12 (x + 3)(x + 2)(x + 1)(x - 1)(x - 3)See attached

A play court on the school playground is in the shape of a square joined to a semicircle. The radius of
the semicircle is 20 feet. What is the perimeter of the play court? Use 3.14 as an approximation for π.
Answers
Answer:
Square side=40ft
Semi-circle diameter=39.98ft
Area of court=2276.69 ft^2
Step-by-step explanation:
The square section has a semicircle joined to it and the combined perimeter is 182.8 ft.
-Area of the square section is obtained by subtracting that of the semicircle from the total(only 3 sides of the square is used since one side is attached to the semi-circle)
Hence, the square's sides has the dimension of 40 ft.
The semi-circle's diameter is calculated as:
Hence, the semi-circle's diameter is 39.98 ft
The area of the court is calculated as:
The court's area is 2,227.69 ft^2

Answers
Answer:

Step-by-step explanation:
The left piece is a little tricky because it does not intersect the y-axis. You know it has a slope of -1, so it will be 1 unit higher than the y-intercept when it is 1 unit left of the y-axis. It ends at (-1, 3). The end point is not included in the definition of the relation, so an open circle is shown.
The right piece crosses the y-axis at y=-3, and has a slope of 2. It ends at (-1, -5). This end point is included, so a solid dot will be found at (-1, -5).
The relation is doubly-defined at x = -1, so there is another solid dot at (-1, -2).

It is incorrect to call this a function, because it fails the vertical line test at x = -1. There are two points on that vertical line. (You may want to discuss this question with your teacher.)

Answers
Using exponential function concepts, it is found that the constant 1.0015 reveals that the quantity increases by 0.15% each decade.
What is an exponential function?An increasing exponential function is modeled by:

[tex]f(t) = 9900(1.0015)^{10t}[/tex]
In which t is the time in decades.
The growth rate is r = 0.0015, as [tex]1 + r = 1.0015 \rightarrow r = 0.0015[/tex], hence the constant 1.0015 reveals that the quantity increases by 0.15% each decade.

There is not enough information given to compare weekly earnings. Please select the best answer from the choices provided A B C D.
Answers
We will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.
How do you find out the best salary option?
Given that, Salary per year = $78,000.
Hourly employees get paid $26 per hour, but get $39 per hour for each hour over 40 hours.
The total number of working hours from Sunday to Saturday is 47.
The payment for 47 hours of work per week will be given below.
Salary per week = [tex]40 \times 26 + 7 \times 39[/tex]
Salary per week = $1313
We know that there are 52 weeks in one year. So the salary for one year is given below.
Salary per year = [tex]1313\times 52[/tex]
Salary per year = $68276
We can see that we calculate the yearly salary with per hour rate, the amount will be lower than the salary per year $78000.
Hence we will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.
