What would be the coordinates of the image if this pre-image is reflected across the x-axis?
A(-2, 2), (1, 1), (3, 1), (2, 4)
B(2,-2), (-1, 1), (-3,-1). (-2,-4)
C(-2, 2), (1, -1), (3, 1). (2,4)
D(-2,-2), (-1, 1), (-3, -1) (-2,-4)
Answers
Answer: C (-2, 2), (1, -1), (3, 1). (2,4)
It will help to rotate the image so the x-axis is horizintal and the y-axis is vertical.
Step-by-step explanation:
Imagine the prefigure twirling on a parallel bar like a gymnast.
When it's up-side down the point that was at (1,1) flips to (1. -1) and the point that was at (3 -1) flips to (3, 1)
As you chech your choices, that knocks out most of the other possibilities.
But you should still verify the other cocorinates.
Hint: if the reflection is across the x-axis, the x values will be the same in the pre-image and the reflection, the y- values will change accorfing to their distance from the x-axis.

The 5 represents height of cuboid.
Step-by-step explanation:
Given:
DeAndre calculated the volume of the cuboid in three ways:
V= 12.5
V= 15.4
V=20.3
To find: what the 12 and the 5 represent in the figure
Solution:
Volume of cuboid is equal to length × breadth × height
or Area of the base of cuboid × height
Length = 4 units
Breadth = 3 units
So, area of base of cuboid = length × breadth = 4 × 3 = 12 square units
Height of cuboid = 5 units
The 12 represents area of base of cuboid.
The 5 represents height of cuboid.
Daryl wishes to save money to provide for his retirement. He is now 30 years old and will be
retiring at age 64. Beginning one month from now, he will begin depositing a fixed amount into
a retirement savings account that will earn 12% compounded monthly. Then one year after
making his final deposit, he will withdraw $100,000 annually for 25 years. In addition, and after
he passes away (assuming he lives 25 years after retirement) he wishes to leave in the fund a sum
worth $1,000,000 to his nephew who is under his charge. The fund will continue to earn 12%
compounded monthly. How much should the monthly deposits be for his retirement plan?
Answers
Answer:
Step-by-step explanation:
Today's Age = 30
Retirement Age = 64
Total Monthly Deposits = ( 64 - 30 ) * 12 = 408
In case of 12% Compounded Monthly , Interest Rate per month = ( 12% / 12 ) = 1%
Effective Interest Rate per year = ( 1 + 0.12/12 )12 - 1 = 1.1268 - 1 = 0.1268 = 12.68%
Present value of Annual 25 Years withdrawal of $100,000 at time of Retirement = $100,000 * PVAF ( 12.68% , 25 )
= $100,000 * 7.4864
= $748,642.20
Present Value of Money for nephew at time of Retirement = $1,000,000 * PVF ( 12.68% , 25 )
= $1,000,000 * 0.050535
= $50,534.52
Now the Present Value of total Amount Required at time of Retirement = $748,642.20 + $50,534.52
= $799,176.70
Now the monthly deposit be X
= X * FVAF ( 408 , 1% ) = $799,176.70
= X * 5752.85 = $799,176.70
X = $138.918
Therefore Monthly Deposit = $138.92

what is k in 26-k/13=28
Answers
Answer:
k = -338
Step-by-step explanation:
The goal is to isolate k on one side, so let's start by multiplying 13 on both sides to get rid of the demoninator. After we do that, we'll be left with:
26 - k = 28(13)
26 - k = 364
Subtracting 26 from both sides gives us:
-k = 338
Multiplying both sides by -1 to make k positive gives us:
k = -338

What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
The given functions are f(x)=x and g(x)=x+5+2.
Translation rules:
When the shape is moved towards the right by k units, then replace x with x + k.
When the shape is moved up by k units, then replace y with y + k.
So, the translation is g(x) is shifted 5 units right and 2 units up from the parent function.
Therefore, option B is the correct answer.

2. Given such, let us create a proportionality as such:
1 = 25,000 ⇒ x - route in cm mapped out
x 210,000
3. Now let us cross multiply, and solve through simple algebra:
210,000 = 25,000 * x,

A theater can seat 160 people . If the theater is 60%full, how many more can fit in the theater
Answers
Answer:
64 people can fit in the theater.
Step-by-step explanation:
If 60% is full then calculate how many people is it
[tex] \frac{60}{100} \times 160 = 96 \\ 160 - 96 = 64[/tex]
64 is 40% of 160
So this many people can be accommodated in the theater
Answer:
64 more people can fit in the theater
Step-by-step explanation:
You need to find 60% of 160
10%=16 (divided by 10)
16×6=96
160 (total people)-96(60%)=64

What the the Quotient 7/12 divided by 2/5
Answers
Answer:35/24
Step-by-step explanation:
7/12 ➗ 2/5
Next step we change divide sign to multiplication,with the numerator and denominator of the right hand fraction inverted
7/12 x 5/2
(7x5)/(12x2)
35/24
The quotient of 7/12 divided by 2/5 is 35/24.
To divide fractions, you need to multiply the first fraction by the reciprocal (or the multiplicative inverse) of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, to find the quotient of 7/12 divided by 2/5, you multiply 7/12 by the reciprocal of 2/5, which is 5/2.
Here are the steps:
Write down the first fraction: 7/12
Write down the reciprocal of the second fraction: 5/2
Multiply the first fraction by the reciprocal: (7/12) x (5/2)
Multiply the numerators: 7 x 5 = 35
Multiply the denominators: 12 x 2 = 24
Simplify the fraction, if possible: 35/24
Therefore, the quotient of 7/12 divided by 2/5 is 35/24.

A boathouse costs $2750 a month to operate, and it spends $650 each
month for every boat that it docks. The boathouse charges a monthly fee of

the profit function of the boathouse?
O A. p = 2750n + 250
O B. p= 900n + 2750
O c. p = 250n- 2750
O D. p = 650n + 2750
Answers
Answer: P=250n-2750
Step-by-step explanation:
The profit function of the boathouse is given as follows p = 250n- 2750.
What is the profit function?The profit function is a mathematical function that reflects a company's or business's profit as a function of the number of products or services produced and sold.
The revenue generated by the boathouse with n boats is given by the monthly fee per boat multiplied by the number of boats, which is $900n.
The total cost to operate the boathouse with n boats is the fixed cost of $2750 plus the variable cost of $650 per boat, which is $2750 + $650n.
Therefore, the profit function of the boathouse is given by the revenue minus the cost:
p = 900n - (2750 + 650n)
Simplifying this expression, we get:
p = 250n - 2750
Thus, the answer is (c) p = 250n - 2750.
