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).
Is 3/8 the same as 1 1/2 of a 4th
(Please give an explanation)
Answers
Answer: Yes.
Step-by-step explanation: 3/8 and 1 1/2 of a fourth are equivalent amounts. To see why, you can use a common denominator to compare the two fractions. If we convert both fractions to eighths, then 3/8 becomes 3/8 and 1 1/2 of a fourth becomes 6/8. Since 3/8 and 6/8 are both equal to 3/4, it follows that 3/8 and 1 1/2 of a fourth are also equal.

$23.76 is the value of XYZ stock when the required return is 12 percent.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Let the price per share be P
growth rate, g = 8% = 0.08
D = Next years dividend = $0.88 × 1.08 = $0.9504
Required rate of return r = 12% = 0.12
P=D/r-g

A marine biologist is studying the growth of a particular species of fish. She writes the following equation to show the length of the fish, f(m), in cm, after m months:
f(m) = 3(1.09)m
Part A: When the marine biologist concluded her study, the length of the fish was approximately 5.98 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(m) represent? (2 points)
Part C: What is the average rate of change of the function f(m) from m = 2 to m = 8, and what does it represent?
Answers
f(m) = 3 * 1.09 * m = 3.27 * m
A:
solve f(m) = 5.98 to find how long it takes for fish to reach that length
5.98 = 3.27 * m
m = 5.98/3.27 = 1.83 months
A reasonable domain would technically depend on other factors like standard deviation, however, a domain of [0,3] could be reasonable without further information.
B:
The y intercept (0 because f(0)=0 ) represents the length of fish at the beginning of the marine biologists study, or when the number of months is zero
C:
Rate of change equals the change in y over the change in x.
[tex]\frac{f(8)-f(2)}{8-2}=\frac{26.16-6.54}{6}=\frac{19.62}{6}=3.27\frac{cm}{month}\\[/tex]
This represents the average number of cm the length of the fish change per month in the interval [2, 8]

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
x = 6.03

A mountainer climbed 1000' at a rate of X feet per hour. He climbed in additional 5000' at a different rate. This rate was 10' per hour less than twice the 1st rate. Which expression represents the number of hours to mountainer climbed?
Answers
The correct option for the equation is C.
What is equation?
An equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =.
Main Body:
Using distance=rate multiplied by time as the formula,
mountaineer climbed 1,000 feet at a rate of x feet per hour
1000 = xt₁ <--eq.1
"He climbed an additional 5,000 feet at a different rate."
5000 = x't₂ <--eq.2
"This rate was 10 feet per hour less than twice the first rate."
x' = 2x - 10 <--eq.3
We now have 3 equations/expressions to solve for the number of hours:
From eq. 1 and 2:
Total time = t₁ +t₂ = t
t = 1000/x + 5000/x'
but x' = 2x - 10
t = 1000/x + 5000/(2x-10)
t = 1000/x + 5000/[2(x-5)]
t = 1000/x + 2500/(x-5)
Hence correct option is C.

Answers
It will take Omari 7 months to pay off the computer.
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.

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
Therefore,
The maximum number of dogs that could have a mass of more than 24kg is 18

On solving the question, we got that - Maricopa Success invested $45000 in stocks, Maricopa Success invested $75000 in bonds and Maricopa Success invested $50000 in CD's.
What is equation?A theorem of equality between two expressions consisting of equations, variables and/or numbers. Essentially, equations are problems, and the development of mathematics has been driven by attempts to find answers to these problems in a systematic way. The equations vary in complexity from simple algebraic equations (containing only addition or multiplication) to differential, exponential equations (containing exponential terms), and integral equations. They are used to express many of the laws of physics. See also system of equations.
Equations -
s + b + C = 170000
11.4s + 4.4b + 3.25C = 1005500
b = C + 25000
And,
Rearrange::
s + b + C = 170000
1140s + 440b + 325C = 100550000
0 + b - C = 25000
Now,
Use any method you know to solve the system to get:
stocks = 45000
bonds = 75000
CD's = 50000

P(x)=_____
(Type an expression using x as the variable. Do not factor.)
Answers
The polynomial function of least degree with rational coefficients so that P(x) = 0 has the given roots.x= -2, x=7 ,will be P(x)=x²-5x+14
What is polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
It is given that the zeroes of the polynomial are, x= -2, x=7
The polynomial expression is obtained as,
=(x+2)(x-7)
=x²-7x+2x+14
=x²-5x+14
Thus, the polynomial function of least degree with rational coefficients so that P(x) = 0 has the given roots.x= -2, x=7 ,will be P(x)=x²-5x+14.
