A division of Chapman Corporation manufactures a pager. The weekly fixed cost for the division is $14,000, and the variable cost for producing x pagers/week in dollars is represented by the function V(x). $ V(x) = 0.000001x^3 - 0.01x^2 + 50x $ The company realizes a revenue in dollars from the sale of x pagers/week represented by the function R(x). $ R(x) = -0.02x^2 + 150x \; \quad \; (0 \leq x \leq 7500) $ (a) Find the total cost function C. What is the profit for the company if 2,600 units are produced and sold each week?
Answer:
P=$-303,424Step-by-step explanation:
given data
fixed cost= $14,000
variable cost function
[tex]V(x) = 0.000001x^3 - 0.01x^2 + 50x[/tex]
revenue function
[tex]R(x) = -0.02x^2 + 150x \; \quad \; (0 \leq x \leq 7500)[/tex]
a. we know that total cost C=fixed cost plus variable cost
C=14000+0.000001x^3 - 0.01x^2 + 50x
[tex]C=14000+0.000001x^3 - 0.01x^2 + 50x[/tex]
profit is given as revenue minus the total cost
P=R(x)-C (x=2600)
[tex]P=-0.02x^2 + 150x -(14000+0.000001x^3 - 0.01x^2 + 50x)[/tex]
substitute x=2600
[tex]P=-0.02(2600)^2 + 150(2600) -(14000+0.000001(2600)^3 - 0.01(2600)^2 + 50(2600))[/tex]
[tex]P=-135200+390000-(1400+17576-67600)[/tex]
[tex]P=-254800-(48624)\\\\P=-254800-48624\\\\P=-303,424[/tex]

Division is one of the four fundamental arithmetic operations. The typing speed of Yousef is 54 words per minute.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Yousef typed a 36-word paragraph in 2/3 minutes. Therefore, the typing speed of Yousef in a minute is,
Typing speed of Yousef = 36 words/ (2/3) minutes
= (36×3)/2 words per minute
= 54 words per minute
Hence, the typing speed of Yousef in a minute is 54 words per minute.

A is at (-2, 1) and B is at (4, -1).
P is a point on y-axis which is equidistant from A and B.
What are the coordinates of P?
Answer:
The coordinates of P are (1,0)
Step-by-step explanation:
Midpoint
The midpoint (xm,ym) of a segment defined by points (x1,y1) and (x2,y2) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
We need to find the coordinates of P which is equidistant from the endpoints A=(-2,1) and B=(4,-1).
Calculate the midpoint:
[tex]\displaystyle x_m=\frac{-2+4}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{1-1}{2}=0[/tex]
Thus, the coordinates of P are (1,0)
Note the midpoint does not lie on the y-axis but on the x-axis.

What is the effect on the graph of f(x) = x2 when it is transformed to

O A. The graph of f(x) is horizontally compressed by a factor of 5 and
shifted 12 units up.
O B. The graph of f(x) is horizontally stretched by a factor of 5 and
shifted 12 units to the left.
C. The graph of f(x) is vertically compressed by a factor of 5 and

O D. The graph of f(x) is vertically compressed by a factor of 5 and

As per transformation of graph, h(x) = ([tex]\frac{1}{5}[/tex])x² + 12 represents that the graph of f(x) is horizontally compressed by a factor of 5 and shifted up 12 units.
What is the transformation of a graph?"Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph. It's a common type of problem in algebra, specifically the modification of algebraic equations.
Given, the graph is f(x) = x².
We know that, at the time of horizontally compressing a graph we need to multiply it by a factor of ([tex]\frac{1}{a}[/tex]).
Again, at the time of shifting a graph up we need to add a positive number of (b).
Therefore, a = 5 and b = 12.
Now, if we horizontally compress f(x) it by a factor of ([tex]\frac{1}{5}[/tex]) then it be ([tex]\frac{1}{5}[/tex])x².
Again, if we shifted up f(x) by 12 units, then it be ([tex]\frac{1}{5}[/tex])x² + 12.
Therefore, h(x) = ([tex]\frac{1}{5}[/tex])x² + 12 represents that the graph of f(x) is horizontally compressed by a factor of 5 and shifted 12 units up.

Write an
equation for the linear function f satisfying the given conditions.
1) f(-1) = -5 and f(5) = 7
Answer: f(x) = 2x - 3
===================================================
We're given f(-1) = -5 and f(5) = 7
This means we know the two points (-1,-5) and (5,7) are on the line.
Find the slope
m = (y2-y1)/(x2-x1)
m = (7-(-5))/(5-(-1))
m = (7+5)/(5+1)
m = 12/6
m = 2
The slope is 2.
Use this along with (x1,y1) to find the equation. We'll use point slope form
y - y1 = m(x - x1)
y - (-5) = 2(x - (-1))
y + 5 = 2(x + 1)
y = 2x + 2 - 5
y = 2x - 3
f(x) = 2x - 3
2) Graph the system of inequalities

Is BAK ~ JOL? Explain your reasoning.
Answer:
Since the ratios are not equal the triangles are not similar
Step-by-step explanation:
Triangle Similarity
For both triangles to be similar, their corresponding side lengths should be proportional by the same scale factor.
Triangle BAK has side lengths: BA=60, AK=38, and KB=36
Triangle JOL has side lengths: JO=50, OL=28, and LJ=26.
Calculating the ratios of the corresponding side lengths:
BA/JO=60/50=1.2
AK/OL=38/28=1.36
KB/LJ=36/26=1.38
Since the ratios are not equal the triangles are not similar

Answer:
Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.
Step-by-step explanation:
Given
Minutes: 10 || 16 || ? || 48
-----Miles: 2.5 || 4 || 7.5 || 12
Required
Which statements solve for the missing value?
First, we need to calculate the ratio of minutes to mile
[tex]Ratio = \frac{Minutes}{Mile}[/tex]
When minutes = 16; mile = 4
So, we have:
[tex]Ratio = \frac{16}{4}[/tex]
[tex]Ratio = 4[/tex]
Next, we multiply the ratio by 7.5
[tex]Minutes = Ratio * 7.5[/tex]
[tex]Minutes =4 * 7.5[/tex]
[tex]Minutes = 30[/tex]

Step-by-step explanation:
Let the Andrew's number is x
Tamar tells Andrew to think of a number, multiply it by five andsubtract three from the result
5x - 3
Manoj tells Andrew to think of a number, add five and multiply the result by three.(x +5)*3
as he was getting the same answer so both the numbers will be equal
5x -3 = (x+5)*3
5x - 3 = 3x + 15
2x = 18
x = 9
a. Andrew's started with number 9
b. (1) 5x- 3 = 5*9 - 3
= 42

= 14*3 = 42
c. Think of a number, then multiply it with 4 then add 6 in it
Think of a number add 12 in it then then double it.

Step-by-step explanation:
In the figure, m<2 = 44. What is the measure of <1?
Answer:
m∠1 = 112°
Step-by-step explanation:
To solve for m∠1, we need to find the supplementary angle and subtract from 180°. We also know that m∠2 = 44° and the remaining two angles inside the triangle are the same because of the congruent sides, let's call each angle x.
Therefore m∠2 + x + x = 180; combine x's
m∠2 + 2x = 180; substitute m∠2 = 44°
44 + 2x = 180; subtract 44 from both sides
2x = 136; divide by 2
x = 68°
Therefore using the supplementary angle
x + m∠1 = 180 (because it is supplementary)
68 + m∠1 = 180; subtract 68 from both sides
m∠1 = 112°

x x 2 + x - 30 = 0 use the commutative property to reorder the terms
2x + x - 30 = 0 collect like terms
3x - 30 = 0 move constant to the right hand side and change its sign
3x = 30 divide both sides of the equation by 3
x = 10
