Can I please get help with this. I am confused as to where I should reflect the quadrilateral ?
Answers
We need to reflect the given quadrilateral across the x-axis.
When we reflect a point across the x-axis, we need to negate the y-coordinate and leave the x-coordinate the same
The point of the given quadrilateral are:
(5,-2)
(2,-4)
(4,-8)
(7,-5)
When we reflect these points on the x-axis, the new points are:
(5,-(-2) = (5,2)
(2,-(-4)=(2,4)
(4,-(-8) =(4,8)
(7,-(-5)=(7,5)

An article claimed that the typical price for a textbook is $84.95. The prices of six textbooks found in a bookstore were $76.95, $84.95, $108.95, $63.95, $75.95, and $84.95.
According to this data, what is wrong with the article's statement?
help please
Answers
The mode is the most common number, as seen in the list of prices, $84.95 is listed twice, therefore making it the most common number, the mode. They should have used the median to find the average price but adding up all the listed prices and dividing by how many prices were listed:
$76.95+$84.95+$108.95+$63.95+$75.95+$84.95 = $495.7
And then divide by 6 (because that’s how many prices were listed):
$495.7/6 = $82.6 <— that is the real mean

Shelby prepared 9 kilograms of dough after working 3 hours. How many hours did Shelby work if she prepared 15 kilograms of dough? Assume the relationship is directly proportional.
Answers
Shelby works for 5 hours to prepare 15 kgs of dough.
Here, we are given that Shelby prepared 9 kilograms (kgs) of dough after working 3 hours.
from this information we can calculate the amount of dough she can prepare in 1 hour.
3 hours ⇒ 9 kgs
1 hour ⇒ 9/3 kgs
9/3 = 3
Thus, she will prepare 3 kgs of dough in 1 hour.
Now, we are given that Shelby prepares 15 kgs of dough in all.
we have, 3 kgs ⇒ 1 hour
Thus, 15 kgs ⇒ 15/3 hours
15/3 = 5
Thus, Shelby works for a total of 5 hours to prepare 15 kgs of dough.

The tangent line to the graph of y=h(x) at the point (-1,4) passes through the point (3,6). Find h(-1) and h'(-1).
Answers
The value for h(-1) is 4
The value for h'(-1) is 1
Given the tangent line to the graph of y=h(x) at the point (-1,4) passes through (3,6), to get h(-1) and h'(-1), we should calculate the following:
Gradient of the tangent line:
Gradient=change in y axis/change in x axis=Δy/Δx
Using the x and y coordinates (-1,4) and (3,6)
Gradient=(6-4)/(3--1)
=2/4
=1/2
Gradient=1/2 or 0.5
Equation of the tangent line:
This should be in the form of y=mx+c, where m is the gradient of the line
We use the gradient and one of the x and y coordinates get the equation of the tangent line
Gradient=change in y axis/change in x axis=Δy/Δx, and gradient was found as 1/2
Δy/Δx=1/2
(y-4)/(x--1)=1/2
(y-4)/(x+1)=1/2
2y-8=x+1
y=(1/2)x+4.5
Equation of the tangent line is y=(1/2)x+4.5 or y=0.5x+4.5
And y=h(x)
So, h(x)=0.5x+4.5
Calculate h(-1), here x=-1:
h(x)=0.5x+4.5
h(-1)=(0.5*-1)+4.5
=4
h(-1)=4
Calculate h'(-1), x=-1:
Here we get the derivative of the equation of the tangent line h(x)=0.5x+4.5,
h'(x)=0.5x^0+0
h'(-1)=1+0
h'(-1)=1

Consequently, we get x + 2x = 5 + 1. 3x = 6 as a result. Consequently, x = 2.

a. Use the formulas shown to write the company's profit function, P, from producing and selling x radios.
b. Find the company's profit if 23,000 radios are produced and sold.
***
Answers
Answer:
(a) The profit function is P(x) = 89x - 90,000.
(b) The company's profit at x=23,000 is 1,957,000.
Step-by-step explanation:
Given,
The cost function of the company is C(x)=90,000 +42x and
The revenue function is R(x) = 47x
where x is the number of radios.
(a)
The company's profit function, P, is from producing and selling x radios is
The formula for profit:
Profit (P) = Revenue (R) - Cost (C)
P = R - C
P = 47x - 90,000 + 42x
P = (47x + 42x) - 90,000
P = 89x - 90,000
For (a), The company's profit function, P, from producing and selling x radios is P = 89x - 90,000
(b)
The radios produced and sold are 23,000
So, x = 23,000
putting x value in the profit function, P
P = 89x - 90,000
P = 89 x 23,000 - 90,000
P = 2,047,000- 90,000
P = 1,957,000
For (b), the company's profit at x = 23,000 is 1,957,000.

Answers
We proved that [tex]\angle2\cong\angle4[/tex].
Given: [tex]\angle2[/tex] and [tex]\angle4[/tex] are vertical.
We have to prove [tex]\angle2\cong\angle4[/tex]
The [tex]\cong[/tex] means congruence which means [tex]\angle2[/tex] and [tex]\angle4[/tex] both have same size and angle. We have to show that they both have same size or angle to prove them congruence.
As we know that the value of straight line is [tex]180^{o}[/tex].
From the given figure we can see that
[tex]\angle1+\angle2=180^{o}[/tex]
[tex]\angle3+\angle4=180^{o}[/tex]
[tex]\angle1+\angle4=180^{o}[/tex]
[tex]\angle2+\angle3=180^{o}[/tex]
To prove the [tex]\angle2\cong\angle4[/tex] we subtract [tex]\angle1+\angle2=180^{o}[/tex] and [tex]\angle1+\angle4=180^{o}[/tex]
[tex]\angle1+\angle2-(\angle1+\angle4)=180^{o}-180^{o}[/tex]
We first simplify bracket. When we multiply with the subtraction sign then the sign under the bracket will changed.
[tex]\angle1+\angle2-\angle1-\angle4=0[/tex]
There have [tex]\angle1[/tex] in addition and subtraction then there only remains
[tex]\angle2-\angle4=0[/tex]
We can write that notation as
[tex]\angle2=\angle4[/tex]
Since [tex]\angle2=\angle4[/tex], that means they both have same angle.

The total surface area of the prism is 217 square inches.
In geometry, a prism is a polyhedron with n sides made of polygons, a second base that is a translation of the first base, and n additional faces that must all be parallelograms and connect the effective distribution of the two bases.
The bases are translated into all cross-sections that are parallel to them.A solid object's surface area is a measurement of the overall space that the object's surface takes up.The base is a square with area = 49 square inches
Length of 1 side = √49 = 7 inches
Area of the triangular sides is given by the formula (1/2) × base × height
Area of each side
= (1/2) × base × height
= (1/2) × 7 × 12
= 42 square inches.
Total surface area
= 42 × 4 + 49
=217 square inches

Congruent in geometry refers to being the same size and shape. Congruence can be used with figures, angles, and line segments. If any two line segments are equal in length, they are said to be congruent. If two angles have the same measure, they are said to be congruent.
Techniques for transformation: In a xy-plane, transformation involves changing the size and shape of an item.

What is dilation?Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Point J (-2, -1) → Point J' (-2 × 1/4, -1 × 1/4) = Point J' (-0.5, -0.25).
Point K (-1, 4) → Point K' (-1 × 1/4, 4 × 1/4) = Point K' (-0.25, 1).

Answers
The integer n = 25 is the only value so that the sector AOB is greater than 20 and less than 30.
How to find the positive integers associated to the diameter of a circle
In this problem we find the sector generated by line segments OA and OB, where O is the center of the circle and the points A and B are on the circle:
20 < 360 / n < 30
20 · n < 360 < 30 · n
First, we determine the factorial decomposition of 360:
360 = 2³ × 3² × 5
Second, find the value of n associated to each limit of the inequality:
Lower limit
360 = (2² × 5) × (2 × 3²)
360 = 20 × 18
n = 18
Upper limit
360 = (2 × 3 × 5) × (2² × 3)
360 = 30 × 12
n = 12
Third, find the values that are between 12 and 18:
x = 2³ × 3
x = 24
n = 360 / 24
n = 15
The only integer that satisfies the inequality is 15.
