Part A: describe the type of function
Part B: what are the standard and factored form of the function
Part C: what are the zeros of the function
Part D: use the zeros to find all of the linear factors
Part E: write the equation of the graphed function
Part F: Use the Y intercept of the graph and your equation from part E to calculate the value of a
Part G; write the equation for the function shown in graph
The type of function of the given graph is polynomial in nature.
Each element of X receives exactly one element of Y when a function from one set to the other is used.
The sets X and Y are collectively referred to as the function's domain and codomain, respectively.In mathematics, a polynomial is an expression made up of coefficients and indeterminates that solely uses the operations of multiplication, addition, and non-negative integer exponentiation.A) The given function is a polynomial of the third degree.
B) The factored form of the polynomial is: [tex]-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]
The standard form is: [tex]p(x)=-\frac{x^3}{1500} -\frac{x^2}{150} +\frac{11x}{60} +1[/tex]
C) The zeroes of the polynomial function are -20, -5 and 15
D) The linear factors are (x+20)(x+5) and (x-15)
E) The equation of the function is [tex]y=-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]
F) From the graph it is seen that the factors of the polynomial function are (x+20)(x+5) and (x-15).
Now at x=0, y=1.
Substituting these values we get:
1=a(0+20)(0+5)(0-15)
or, a = [tex]-\frac{1}{1500}[/tex]
So the value of a for the equation is [tex]-\frac{1}{1500}[/tex] .
G) The equation for the function in the graph is
[tex]y=-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]

6. A glider descends 240 meters in 12 seconds. What is the average change in
elevation per second?
Answer:
20 meters per second
Step-by-step explanation:
240/12
Answer: The average change in elevation per second is -20 meters.
Step-by-step explanation: If a glider descends 240 meters in 12 seconds, then it descends 20 meters in one second. However, because the glider is descending, then the value and slope of change must be negative.

Consider the given equation is [tex]3-2x=15[/tex] and one of the 6 in the options is -6.
Given:
The equation is
[tex]3-2x=15[/tex]
To find:
The value of x.
Solution:
We have,
[tex]3-2x=15[/tex]
Subtracting 3 from both sides, we get
[tex]3-2x-3=15-3[/tex]
[tex]-2x=12[/tex]
Divide both sides by -2.
[tex]x=\dfrac{12}{-2}[/tex]
[tex]x=-6[/tex]
Therefore, the value of x is -6.
a family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads. each member of the family averages 8 minutes in the shower per day. how many gallons will the entire family (5 people) save per day?
The entire family (5 people) save 120 gallons per day.
Subtraction:
Subtraction means we have to find the difference of the numbers.
Given,
A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads.
Each member of the family averages 8 minutes in the shower per day.
Here we need to find the entire family savings per day.
According to the question,
The total bath time for the whole family is,
=> 8 x 5 = 40
So for one day,
If the showerheads cost 5 gallon per minute, then the cost for the family is,
=> 40 x 5 = 200
If the showerheads cost 2 gallon per minute, then the cost for the family is,
=> 40 x 2 = 80
So, the savings is,
=> 200 - 80
=> 120
So, they save 120 gallons per day.

How much is 2+45/6?
Answer:
The correct answer to 2+45/6 is either 9.5 or 9 1/2.
Step-by-step explanation:
In order to solve 2 + 45/6, we need to turn the fraction into a decimal (by dividing the numerator by the denominator) and/or a mixed number (by dividing the numerator by the denominator, and marking the rest)
Step 1: Convert fraction into decimal/mixed number:
45/6 or 45 ÷ 6 = 7.5
45/6 = 7 3/6 or 7 1/2
Step 2: Add two to Both the decimal/mixed number:
7.5 + 2 = 9.5
7 1/2 + 2 = 9 1/2
Therefore, 2+45/6 is either 9.5 or 9 1/2.

The formula for figuring straight-time pay is
your hourly rate divided by the number of
hours worked in a week. T or f
Your hourly wage is divided by the number of hours worked in a week to determine straight-time pay. :- False
The entire set amount of money provided to an employee over a specific time period—typically a year—is referred to as a salary. The amount paid to an employee for each hour of work is known as their hourly wage in comparison.
Let's assume the straight time pay to be x.
Let the hourly pay rate be y
If a person has worked N no. of hours in a week.
Then the straight-time pay will be the product of the hourly pay rate and the number of hours the person worked.
Therefore,
The straight time pay, x = N × y = Ny
Hence, the statement " the formula for figuring straight time pay is your hourly rate divided by the number of hours worked in a week" is false.

Marty and Ethan both wrote a function, but in different ways.

Ethan
A two column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 9.2, 9.6, 10, 10.4.
Whose function has the larger slope?
Answer:
Marty's function has larger slope as compared to Ethan's slope.
Step-by-step explanation:
Marty function:
y plus 3 equals StartFraction 1 Over 3 EndFraction left-parenthesis x plus 9 right-parenthesis.
Writing in mathematical form: [tex]y+3=\frac{1}{3}(x+9)[/tex]
Marty has written expression in point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where m is slope
So, comparing Marty's equation with general point-slope form equation we get slope [tex]m=\frac{1}{3}\:or\: 0.3[/tex]
Now, Ethan has a table
x y
-4 9.2
-2 9.6
0 10
2 10.4
We can find slope using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Using any two points, we can find slope of Ethan's equation
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{9.6-9.2}{-2-(-4)} \\Slope=\frac{0.4}{-2+4} \\Slope=\frac{0.4}{2} \\Slope=0.2[/tex]
So, we get Marty's slope = 0.3
Ethan's slope = 0.2
So, Marty's function has larger slope as 0.3 is greater than 0.2

First multiply 7 by 4 which is 28. You keep the 8 as part of your answer, and put 2 above 3 in other words regroup.
Next multiply 3 by 4 which is 12 and add 2 which equals 14. Again, leave the 4 as part of your answer and put the 1 over the 3 in other words regroup.
Then multiply 8 by 3 and add 1 which equals 33.
