Answer:
Step-by-step explanation:
Part A
x-intercepts of the graph represent the value of goods at which profit of of the company is zero → Break even of the company
Maximum value of the graph represents the maximum profit of the company at certain price of the goods.
Part B
Interval in which the function is increasing → x = 0 to x = $3
Profit of the company increases when price of the goods increase from 0 to 3.
Interval in which the function is decreasing → x = $3 to x = $6
Profit of the company decreases when the price of the goods increases from 3 to 6.
Part C
Average rate of change of the function from x = a and x = b,
= [tex]\frac{f(b)-f(a)}{b-a}[/tex]
By applying the same rule,
Average rate of change of the function between x = 1 and x = 3
= [tex]\frac{120-60}{3-1}[/tex]
= [tex]\frac{60}{2}[/tex]
= 30
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=71°, and DB = 67 feet. Find the length of BC to the nearest tenth of a foot.
Answer: Side BC would be 205.7ft
Step-by-step explanation:
Answer:
in triangle BCD
relationship between base and hypotenuse is given by cos angle
cos 71=b/h
cos71=BD/BC
cos71=67/x
x=67/cos71=205.8ft.
the length of BC to the nearest tenth of a foot is 206ft.

If 9(x + 5) = 63 , what is the value of x + 5 ?
given f(x) = 5x4- 3x2+ 6x+2. Find f(-2)
.
P(x) is a polynomial.
P(x) divided by (x – 8) has a remainder of 5.
P(x) divided by (x – 5) has a remainder of 3.
P(x) divided by (x + 5) has a remainder of -2.
P(x) divided by (x + 8) has a remainder of 0.
Find the following values of P(x).
P(5) =
P(-8) =
Answer:
x-5 = 0 has a remainder of 3
x = 5
therefore p(5) = 3
x+8 = 0 has a remainder of 0
x = -8
therefore p(-8) = 0
Which inequality represents "six times a number is less than negative thirty-nine and three-quarters"? 6x > –39Three-fourths 6 + x > -39 Three-fourths 6x < -39Three-fourths 6 x less-than-or-equal-to negative 39 and three-fourths
Given:
The phrase is "six times a number is less than negative thirty-nine and three-quarters".
To find:
The inequality represented by the given phrase.
Solution:
Let x be the unknown number.
Six times a number is "6x".
Less than is "<".
Negative thirty-nine and three-quarters is "[tex]-39\dfrac{3}{4}[/tex]".
So, six times a number is less than negative thirty-nine and three-quarters is:
[tex]6x<-39\dfrac{3}{4}[/tex]
Therefore, the correct option is C.
Answer:
"six times a number is less than negative thirty-nine and three-quarters".
Step-by-step explanation:

Consider best strategy to solve the problem. If 9 inches are equal to 27 feet on a map how many feet are equal to three inches
Answer:
9
Step-by-step explanation:
If 9 inches equal 27 what you would do is divide in order to find how much feet would be in 1 inch. So:
9/27= 3 feet
Then to find how much feet are equal to 3 inches you just multiply that by 3. So your answer is 9 feet.
Overall the work should look like
9 inches= 27 feet
9/9 inches= 27/9 feet
1 inch = 3 feet
3 inches x 3 feet
= 9

Answer:
A2 = 120
A3 = 60
A5 = 60
A6 = 120
Step-by-step explanation:
Angle 1 and 2 are supplementary, so A2 = 180 - 60, which is 120.
Angle 1 and 3 are vertical angles, which are always the same measure.
Angle 5 is alternate interior angles with 3, which means it is also 60.
Angle 6 is alternate interior angles with 4, which means it is 120.

The Area of EFGH is 2x+9 which is similar to The Area of JKLM is 2x-6. The perimeter of EFGH is x+3 which is similar to the Perimeter of JKLM is x-1. FInd all Possible values of X.
Answer:
[tex]x = 9[/tex]
Step-by-step explanation:
Assume EFGH and JKLM are rectangles
JKLM appears to be the smaller of both.
So:
[tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
Where n is the scale of dilation
The area of EFGH is:
[tex]Area = EF * GH[/tex] ----- (1)
Substitute [tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
[tex]Area = n*JK * n*LM[/tex]
[tex]Area = n^2*JK * LM[/tex]
So, we have:
[tex]Area = EF * GH[/tex] and [tex]Area = n^2*JK * LM[/tex]
[tex]EF * GH = 2x + 9[/tex] --- Given
[tex]JK * LM = 2x - 6[/tex] --- Given
So:
[tex]Area = EF * GH[/tex] and [tex]Area = n^2*JK * LM[/tex]
[tex]Area = 2x + 9[/tex] and [tex]Area = n^2 * (2x - 6)[/tex]
Equate bot areas
[tex]2x + 9 = n^2*(2x - 6)[/tex]
Make n^2 the subject
[tex]n^2 = \frac{2x + 9}{2x - 6}[/tex]
The perimeter (P) of EFGH is:
[tex]P = 2*(EF + GH)[/tex] ----- (1)
Substitute [tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
[tex]P = 2*(n*JK + n*LM)[/tex]
[tex]P = 2n*(JK + LM)[/tex]
So, we have:
[tex]P = 2*(EF + GH)[/tex] and [tex]P = 2n*(JK + LM)[/tex]
[tex]2*(EF + GH) = x + 3[/tex] --- Given
[tex]2*(JK + LM) = x - 1[/tex] --- Given
So:
[tex]P = 2*(EF + GH)[/tex] and [tex]P = 2n*(JK + LM)[/tex]
[tex]P =x + 3[/tex] and [tex]P = n *(x - 1)[/tex]
Equate bot perimeters
[tex]x + 3 = n(x - 1)[/tex]
Make n the subject
[tex]n =\frac{x + 3}{x - 1}[/tex]
Square both sides
[tex]n^2 =\frac{(x + 3)^2}{(x - 1)^2}[/tex]
Recall that: [tex]n^2 = \frac{2x + 9}{2x - 6}[/tex]
So, we have:
[tex]\frac{(x + 3)^2}{(x - 1)^2} = \frac{2x + 9}{2x - 6}[/tex]
Evaluate all squares
[tex]\frac{x^2 + 6x +9}{x^2 - 2x + 1} = \frac{2x + 9}{2x - 6}[/tex]
Cross multiply
[tex](x^2 + 6x +9)(2x - 6) = (x^2 - 2x + 1)(2x + 9)[/tex]
Open brackets
[tex]2x^3 +12x^2 + 18x - 6x^2 -36x -54 = 2x^3 - 4x^2 + 2x + 9x^2 - 18x +9[/tex]
Subtract 2x^3 from both sides
[tex]12x^2 + 18x - 6x^2 -36x -54 = - 4x^2 + 2x + 9x^2 - 18x +9[/tex]
Collect like terms
[tex]12x^2 - 6x^2 + 18x -36x -54 = - 4x^2 + 9x^2+ 2x - 18x +9[/tex]
[tex]6x^2 - 18x -54 = 5x^2- 16x +9[/tex]
Collect like terms
[tex]6x^2 -5x^2 - 18x +16x -54 -9= 0[/tex]
[tex]x^2 -2x -63= 0[/tex]
Expand
[tex]x^2 +7x - 9x - 63 = 0[/tex]
Factorize
[tex]x(x +7) - 9(x + 7) = 0[/tex]
[tex](x -9) (x + 7) = 0[/tex]
[tex]x = 9\ or\ -7[/tex]
x can not be negative.
So: [tex]x = 9[/tex]

A circle with radius of \greenD{1\,\text{cm}}1cmstart color #1fab54, 1, start text, c, m, end text, end color #1fab54 sits inside a \blueD{3\,\text{cm} \times 3\,\text{cm}}3cm×3cmstart color #11accd, 3, start text, c, m, end text, times, 3, start text, c, m, end text, end color #11accd rectangle. What is the area of the shaded region?
Answer:
5.86cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the circle
Area of rectangle = Length * Width
Area of rectangle = 3cm * 3cm
Area of rectangle = 9cm²
Area of the circle = πr²
Given radius r = 1cm
Area of the circle = 3.14(1)²
Area of the circle = 3.14cm²
Area of the shaded region = 9 - 3.14
Area of the shaded region = 5.86cm²
Answer:
5.86cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the circle
Area of rectangle = Length * Width
Area of rectangle = 3cm * 3cm
Area of rectangle = 9cm²
Area of the circle = πr²
Given radius r = 1cm
Area of the circle = 3.14(1)²
Area of the circle = 3.14cm²
Area of the shaded region = 9 - 3.14
Area of the shaded region = 5.86cm²
