A(2, 5), B(2, -3), and D(-6, 5) are three vertices of square ABCD. What are the coordinates of the fourth vertex, C?
Answers
Answer:
C(-6, -3)
Step-by-step explanation:
In a square, all four sides have the same length and all four angles have the same measure (90 degrees). Therefore, the line segments connecting the vertices of a square are all perpendicular to each other and all have the same length.
Since the line segment AB has a length of 8 (the difference in the y-coordinates is 8) and a horizontal component (the difference in the x-coordinates is 0), the line segment CD must also have a length of 8 and a horizontal component of 0. This means that the x-coordinate of point C is the same as the x-coordinate of point A, which is 2.
The line segment CD also has a vertical component equal to the difference in the y-coordinates of points D and A, which is 5 - (-3) = 8. Therefore, the y-coordinate of point C is the same as the y-coordinate of point D minus 8, or -3.
Therefore, the coordinates of point C are (-6, -3).

140 miles from home?
A. 2 hours
B. 4 hours
C. 7 hours
D. 8 hours
Answers
Time taken by the bicyclist is 8 hours.
What is slope?Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Given slope = 35 / 2 = 17.5
Distance = 140 miles.
then time is calculated by 140 /17.5
= 8 hours
The slope expresses how quickly the dependent variable changes when the independent variable changes. The Greek capital letter D or D is frequently used by mathematicians and economics to represent change. Slope contrasts the change in the vertical axis, y, with the change in the horizontal axis, x.
As x grows, there are 4 different sorts of slopes: negative, positive, zero, and undefined. The "average rate of change" can also be thought of as the slope of a line.

The pressure of 28 inches of mercury occurs at 6.03 miles from the eyes of the hurricane
How to determine the distance?From the question, we have the following pressure function that can be used in our computation:
f(x) = 0.48 ln(x + 2) + 27
Also from the question, we have
Pressure = 28 inches
This means that
f(x) = 28
So, we have the following equation
0.48 ln(x + 2) + 27 = 28
Subtract 27 from both sides
0.48 ln(x + 2) = 1
Divide 0.48 from both sides
ln(x + 2) = 2.083
Take the exponent of both sides
x + 2 = 8.03
So, we have

What is a percentage?
Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) besides the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
To find the amount of the down payment, multiply the price of the computer by the down payment percentage:
down payment = $1,099 * 20% = $219.80
The remaining balance on the computer after the down payment is:
remaining balance = $1,099 - $219.80 = $879.20
To find the total number of months it will take Omari to pay off the computer, divide the remaining balance by the monthly payment:
total months = $879.20 / $144/month = 6.1 months
Since it is not possible to have a fraction of a month.

Maximum and Minimum values of a function:Using fundamental algebraic principles, rearrange the function to get the value of x at the derivative value of 0. The maximum or minimum will be at the vertex of the function, which is indicated by the response's x-coordinate. Rewrite the answer into the original function to determine the minimum or maximum.
Here we have
The given shows the masses of various dogs
Mass (x) kg frequency
0 ≤ x < 10 2
10 ≤ x < 20 7
20 ≤ x < 30 12
30 ≤ x < 40 6
a) The minimum number of dogs that have a mass of more than 24kg.
If we observe the given table the mass of 24 kg will lie in class intervals 20 ≤ x < 30, 30 ≤ x < 40
In class interval 20 ≤ x < 30, mass ranges from 20 kg to 30 kg there is a possibility that the mass of dag will be less than 24 since it started from 20 kg,
In class interval 30 ≤ x < 40, mass ranges from 30 kg to 40 here there is no possibility that the mass will be less than 24 kg.
So here we can take the frequency of class interval 30 ≤ x < 40 as the Minimum value or number of dogs that could have a mass of more than 24 kg
Therefore,
The minimum number of dogs that have a mass of more than 24kg is 6
b) The maximum number of dogs that have a mass of more than 24kg.
In the above case since we are calculating minimum value, we didn't consider class interval 20 ≤ x < 30.
In this case, to get the maximum value or a maximum number of dogs we will consider class interval 20 ≤ x < 30 as there is a possibility that the mass could be more than 24 kg
In class interval 30 ≤ x < 40 the mass will always be more than 24 kg.
Thus, the Maximum number of dogs with more than 24 kg = 12 + 6 = 18

2x + 7 = (-88):(-8)
2x + 7 = 11
2x = 11 – 7
2x = 4
x = 4:2
x = 2
I hope my answer helps you.
An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 8.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 24 engines and the mean pressure was 8.4 pounds/square inch with a standard deviation of 1.0 A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.

The decision for rejecting the null hypothesis is μ = 8.4
In statistics the term hypothesis refers a tentative statement about the relationship between two or more variables.
Here we have given that engineer designed a valve that will regulate water pressure on an automobile engine and he is designed the valve such that it would produce a mean pressure of 8.0 pounds/square inch. Then it is believed that the valve performs above the specifications. Where the valve was tested on 24 engines and the mean pressure was 8.4 pounds/square inch with a standard deviation of 1.0 Here the level of significance of 0.05 will be used.
Here we have to determine the decision for rejecting the null hypothesis.
While we looking into the the given question we have identified the following values,
Standard deviation = 1.0
Mean pressure = 8.4 pounds/square
Level of significance = 0.05
Sample size = 24
According to these values the null and alternative hypothesis is written as,
H0 = μ = 8.4
Hx = μ ≠ 8.4
Therefore, H0 = μ = 8.4 is the decision for this one.

What is excel commands?
The following describe the commands in Excel: They carry out tasks the same way users do. They can change Excel settings, open, close, and edit documents, start recalculations, and other actions that users may perform (within the bounds of the interface being utilized). Excel's command menu interface is called the Ribbon. It logically and visually groups together frequently used actions. These make up the Ribbon's principal components. Related groupings of commands are grouped together by tabs.
