========================================================
Explanation:
Draw a horizontal line through 10 on the y axis. This is because R(x) = 10 is the same as y = 10. The output of the function is the y value.
See the diagram below.
The horizontal line crosses the parabola at two locations. From those points, draw a vertical line straight down to the x axis. Note how we land at x = 2 and x = 10. This means that R(2) = 10 and R(10) = 10.

To solve the problem "56 is what percent of 70?", Noah uses the double number line below. On the double number line, write the correct numbers at each unlabeled tick mark. Then solve the problem. Explain your answer
Answers
Answer:
80%
Step-by-step explanation:
I have filled out and attached the double number line below. From the picture, we can see that the number 56 is 80% of 70. In the image, this is represented by the second number line where 80% is on the same tick as 56 is on the first number line. Mathematically this can be calculated by dividing 56 by 70 and then multiplying that decimal value by 100 to get the percentage like so...
56 / 70 = 0.8
0.8 * 100 = 80%

The area is 35 square units.
Step-by-step explanation:
The entire figure is formed by four triangles and a rectangle, whose sum represents the total area ([tex]A_{T}[/tex]), in square units, represented by the following formula:
[tex]A_{T} = A_{1} + A_{2} + A_{3} + A_{4} + A_{5}[/tex] (1)
Where:
[tex]A_{1}[/tex], [tex]A_{2}[/tex], [tex]A_{3}[/tex], [tex]A_{4}[/tex] - Areas of the four triangles.
[tex]A_{5}[/tex] - Area of the rectangle.
By using the area formulas of a triangle and rectangle we expand the equation described above:
[tex]A_{T} = \frac{1}{2}\cdot (3)\cdot (6) + \frac{1}{2}\cdot (3)\cdot (2) + \frac{1}{2}\cdot (2)\cdot (2) + \frac{1}{2}\cdot (3)\cdot (6) + (2)\cdot (6)[/tex]
[tex]A_{T} = 35\,u^{2}[/tex]
The area is 35 square units.

Find the value of x/y.
Answers
Answer:
x = 12 y y = 29x
29 12
Step-by-step explanation:
Cross multiply to get
5(7x - 3y) = -3(y - 2x)
35x - 15y = -3y + 6x
35x - 6x = -3y + 15y
29x = 12y
x = 12y / 29
x/y = 12 / 29

Which polar coordinates represent the same point as the rectangular coordinates (-4,5)?
Answers
Answer:
2nd option
Step-by-step explanation:
To convert from (x, y ) → (r, θ )
where
r = [tex]\sqrt{x^2+y^2}[/tex]
θ = [tex]tan^{-1}[/tex] ([tex]\frac{y}{x}[/tex] )
Here (x, y ) = (- 4, 5 ), a point in the 2nd quadrant
r = [tex]\sqrt{(-4)^2+5^2}[/tex] = [tex]\sqrt{16+25}[/tex] = [tex]\sqrt{41}[/tex]
θ = [tex]tan^{-1}[/tex] ([tex]\frac{5}{4}[/tex] ) ≈ 51.3° ← related acute angle , then
θ = 180° - 51.3° = 128.7°
Thus
(- 4, 5 ) → ([tex]\sqrt{41}[/tex], 128.7° ) in polar form

Step-by-step explanation:
The telemarketer made 200 phone calls and only 35 people signed up. Therefore, we need to find the amount of people who didnt.
200 - 35 = 165
165 people did not sign up.
This meants that the frequency of getting a customer is 35/200 and not is 165/200. In percentages,
The relative frequency of not getting a customer is 82.5%
The relative frequency of getting a customer is 17.5%

A video uploaded had 54 upvotes if the ratio of up votes to down votes was 9:8 how many down votes did the video get
Answers
Answer:
48
Step-by-step explanation:
Given data
Ratio= 9:8
Combined ratio= 9+8= 17
Upvotes= 54
Let us apply the part to all approach to find the total votes
let the total votes be x
9/17= 54/x
cross multiply
9x= 54*17
9x= 918
divide both sides by 9
x= 918/9
x=102
Hence the number of downvotes is
=102-54

either (x-1)=0 Or,(x+4)=0
x-1=0
x=0+1
x=1
x+4=0
x=0-4
x=-4
therefore x=-4,1
Step-by-step explanation:
The required solutions for x are x₁= 1 and x₁= -4, and we can write them from least to greatest as -4, 1.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
To solve for x in the quadratic equation x² + 3x - 4 = 0, we can use the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation (ax² + bx + c = 0).
In this case, a = 1, b = 3, and c = -4, so we have:
x = (-3 ± √(3² - 4(1)(-4))) / 2(1)
x = (-3 ± √(25)) / 2
x = (-3 ± 5) / 2
x₁ = (-3 + 5) / 2 = 1
x₂ = (-3 - 5) / 2 = -4
Therefore, the solutions for x are x₁= 1 and x₁= -4, and we can write them from least to greatest as -4, 1.
