The revenue made by a motorcycle company from the sale of x motorcycles is given by 0.003x^2 + 9x. The cost to produce x motorcycles is given by the polynomial 13x+400,000. Form a polynomial expression written in simplified standard form for the profit from making and selling x motorcycles.
The profit expression from selling x motorcycles expressed as a polynomial is : -0.003x² + 4x + 400000
The value of profit cab be found using the expression :
Profit = (Cost of production - Revenue)
Profit = (Cost of production - Revenue) Cost of production = 13x + 400000
Profit = (Cost of production - Revenue) Cost of production = 13x + 400000Revenue = 0.003x² + 9x
Profit = (13x + 400000) - (0.003x² + 9x)
Profit = 13x + 400000 - 0.003x² - 9x
Profit = 13x - 9x + 400000 - 0.003x²
Profit = 4x + 400000 - 0.003x²
The polynomial in simplified standard form can be expressed thus : -0.003x² + 4x + 400000

P(x) = x^4+ax^3-x^2+bx-12 has factors of (x-2) and (x+1). Solve the equation P(x)=0
Answer:
because P(x) has factors of (x-2) and (x+1) => x = 2 and x = -1 are the solutions of P(x)
so we have:
[tex]\left \{ {{2^{4}+2^{3}a-2^{2}+2b-12 =0} \atop {1-a-1-b-12=0}} \right.\\=>\left \{ {{8a+2b=0} \atop {a+b=-12}} \right.\\<=>\left \{ {{4a+b=0} \atop {a+b=-12}} \right.\\<=>\left \{ {{a=4} \atop {b=-16}} \right.[/tex]

If Jordan had his hourly salary increase from $9.25 per hour to $10.75 per hour, which of the following is
closest to the percent increase in Jordan's salary?
The solution is, the percent of the increase is 16.22%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
If Jordan had his hourly salary increase from $9.25 per hour to $10.75 per hour.
now, we have,
The percent of increase can be calculated as:
vf - vi/ vi * 100
Where vf is the final value and vi is the initial value.
So, replacing vf by 10.75 and vi by 9.25, we get:
1.5 / 9.25 * 100
= 16.22%
Therefore, the percent of the increase is 16.22%

3. If Adam Ct. is perpendicular to Bertha Dr. and Charles St., what must be true? (1 point)
O Adam Ct. I Edward Rd.
O Bertha Dr. || Charles St.
O Dana La. I Charles St.
Step-by-step explanation:
Option B. Here Adam Ct. is perpendicular to Betha Dr. and Charles. So, St. Bertha Dr. || Charles St. Since they are parallel to each other
Answer: Bertha Dr. || Charles St.
Step-by-step explanation:
Parallel lines are lines in a plane that do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.
A line is said to be perpendicular to another line if the two lines intersect at a right angle.
Adam Court is perpendicular to Edward Road.
Bertha Drive is parallel to Charles St.
Dana Lane is perpendicular to Edward Road.

If the zeros of a quadratic function are 3 and 8, what are the factors of the function? 3and (x – 3) B. (X- 8) and (x + 3) O C. (X + 8) and (x + 3) 00. (X - 8) and (x-3) Reset Next
Answer: Choice D
(x - 8) and (x - 3)
===============================================
Explanation:
The term "root" is the same as "zeros of a function".
If 3 is a root, then x = 3 leads to x-3 = 0 after subtracting 3 from both sides.
If 8 is a root, then x = 8 leads to x-8 = 0 for similar reasoning
Use of the zero product property allows us to combine those two rules into the following
(x-3)(x-8) = 0
This shows that the two factors are (x-8) and (x-3)
The order of the factors doesn't matter because we can multiply two numbers in any order.

7. Given directed line segment RT below, find the coordinates of S such that the ratio of RS to ST is 5:1. Plot point S
A line can be divided in proportions using ratios. The point at which a line is divided in ratios is calculated using: [tex][\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
The coordinate of S is: [tex](6,\frac{8}{3})[/tex]Given that:
[tex]RS : ST = 5 : 1[/tex]
The coordinates of RT are not given. So, I will solve using a general explanation.
When a line is divided into ratios, the point (S) at which the line is divided is calculated using the following line ratio formula:
[tex]S = [\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
Assume the coordinate of R and T is:
[tex]R = (1,6)\\T = (7,2)[/tex]
[tex]RS : ST = 5 : 1[/tex] means:
[tex]m:n = 5:1[/tex]
So, point S is:
[tex]S = [\frac{5\times 7+ 1 \times 1}{5+1},\frac{5 \times 2+ 1 \times 6}{5+1}][/tex]
[tex]S = [\frac{36}{6},\frac{16}{6}][/tex]
[tex]S = [6,\frac{8}{3}][/tex]
Hence, if the coordinates of R and T are:
[tex]R = (1,6)\\T = (7,2)[/tex]
And the line ratio is:
[tex]m:n = 5:1[/tex]
The coordinate of S is:
[tex]S = [6,\frac{8}{3}][/tex]
