graph of triangle ABC with vertices at negative 2 comma negative 2, 3 comma 3, 2 comma negative 5
Determine the coordinates of triangle A′B′C′ if triangle ABC is rotated 270° clockwise.
A′(−2, 2), B′(3, −3), C′(−5, −2)
A′(2, −2), B′(−3, 3), C′(5, 2)
A′(2, 2), B′(−3, −3), C′(5, −2)
A′(2, −2), B′(−3, 3), C′(2, 5)
Answers
Answer:
A(2,-2) B(-3,3) C(5,2)
Step-by-step explanation:
To rotate a point (x, y) 270° clockwise, we can swap the x and y coordinates and then negate the new x-coordinate. So, The correct answer is: A′(-2, 2), B′(3, −3), C′(-5, −2)
Let's apply this rotation to each vertex of triangle ABC:
Vertex A(-2, -2):
A' = (y, -x) = (-2, 2)
Vertex B(3, 3):
B' = (y, -x) = (3, -3)
Vertex C(2, -5):
C' = (y, -x) = (-5, -2)
Now, let's compare the coordinates of the rotated triangle A'B'C' with the given options:
Option 1: A'(−2, 2), B'(3, −3), C'(−5, −2) - These are the correct coordinates for the rotated triangle.
Option 2: A'(2, −2), B'(−3, 3), C'(5, 2) - This doesn't match the coordinates we found.
Option 3: A'(2, 2), B'(−3, −3), C'(5, −2) - This doesn't match the coordinates we found.
Option 4: A'(2, −2), B'(−3, 3), C'(2, 5) - This doesn't match the coordinates we found.
Therefore, the correct answer is:
A′(-2, 2), B′(3, −3), C′(-5, −2)

Turn on your calculator and make sure it's in degree mode (not radian or grad).
Type in "4" followed by the square root symbol (√).
Type in "3".
Press the equals (=) button to get the answer.
The answer you get on your calculator is likely a decimal approximation. In this case, it should be approximately 6.92820323.
So, the decimal approximation of 4√3 is approximately 6.92820323. Note that the approximation is not exact, but it is usually sufficient for most practical purposes.
Suppose a bag contains 30 white marbles, 10 purple marbles, and 8 green marbles.
One marble is randomly selected from the bag. In this situation, the probability of 1 could represent which event?
a. not selecting a yellow marble
b. selecting either a white or purple marble
c. selecting a green marble
d. selecting a white marble
Which BEST describes the probability of selecting a purple marble?
a. Likely
b. Certain
c. Impossible
d. Not likely
Answers
For our first question, the answer is A. This is because our bag does not contain any yellow marble, which means that it is impossible to get a yellow marble, which is why you would never pick a yellow marble from the bag. Hence why our answer is A.
For our second question, the answer is D. This is mainly because we have a total of 48 marbles and only 10 purple ones. This is a 10 out of 48 chance of getting a purple marble, which when converted into a percentage, we would get a 20.8% of getting a purple marble. Remember that this is our rule:
Impossible = 0%
Unlikely = Anything below 50% but above 0%
Equally Likely = Exactly 50%
Likely = Anything above 50% but below 100%
Certain = 100%
Using this rule, we know that 20.8% is unlikely, which is why it’s answer choice D.

Ken’s seventh grade class plans to collect empty aluminum pop cans as a fund raiser to
buy two new books for the school library. The books will cost a total of $50.
Answers
a.) The number of pounds of empty cans needed by the class is 200 pounds.
b.) The number of empty cans needed by the class to collect are 5486 cans.
The books will cost a total amount of $ 50.
If $ 0.25 per pound is the current price for aluminium at the recycling centre, the number of pounds the class will have to collect is found by dividing the total amount needed by cost per pound is,
⇒ 50/0.25 = 200
b.) Six empty cans weigh 3.5 ounces.
1 pound = 16 ounces
200 pounds = 200 × 16 = 3200 number of ounces
3200/3.5 = 914.29
914.29 × 6 = 5485.7 cans ≈ 5486 cans

The table shows the cost, c, of making different numbers of shirts, t. Create an equation to model the cost.
Number of Shirts, t 100 250 500
Cost to Company, c $600.00 $1,387.50 $2,700.00
Answers
Answer: c=(5.25)t+75
Step-by-step explanation:
To solve this problem, we need to think of this as a graph. First, we find the slope of our two coordinate points. There are three given: (100,600) (250,1387.5) and (500,2700)
We know that the number of shirts will be x in this equation because it is the independent variable. The cost to the company depends on the number of shirts made.
I like to choose whole numbers because they are the easiest to work with. Therefore, I will choose the coordinates (100,600) and (500,2700)
Now we use the slope formula:
2700-600/500-100
=2100/400
=5.25
To check to make sure that the slope is consistent throughout, we can look at our other coordinate: (250,1387.5)
Use the slope formula to check:
1387.5-600/250-100
=787.5/150
=5.25
Now we know that we have a consistent slope, the next step is to find the y-intercept.
(You could also use the point-slope formula, which would give you the entire equation outright. Although it is faster, there is more potential for an accidental mistake, so I like to use this method, although this method will be a bit slower.)
To find the y-intercept with a slope and point, use the equation y=mx+b.
y=(5.25)x+b
Now we can take a point and substitute it in. I'm going to use the point (100,600) as it is the easiest one.
600=5.25(100)+b
600=525+b
b=600-525
=75
Therefore, the equation is c=(5.25)t+75.

you currently have 225$ in your bank account you make withdrawals of 445$ and 30$ and then deposit 90$ what is the balance of the account now? Please thank you so much
Answers
Answer: -$160
Step-by-step explanation:
Start with $225
withdrawal means subtract $445
225-445 = - 220
you are now in negatives because you took more than you had
you take out another $30
-220 - 30 = -250 you are even more negative because you took out more
but you deposit, put back $90, means add
-250 +90 = -160 you are still negative because you didn't put back enough
-$160
Steps:
225-445=-220
-220-30=-250
-250+90=-160

Put the following quadratic into vertex
form by completing the square: y =
- 3x - 1.
= 4x²
Answers
Factor out the coefficient of x² from the first two terms:
y = 4(x² - (3/4)x) - 1
Complete the square by adding and subtracting the square of half of the coefficient of x, which is (3/8)² = 9/64:
y = 4(x² - (3/4)x + 9/64 - 9/64) - 1
Group the first three terms and factor the perfect square trinomial:
y = 4[(x - (3/8))² - 9/64] - 1
Simplify by distributing the 4 and combining like terms:
y = 4(x - (3/8))² - (1 + 9/16)
Rewrite the constant term as a fraction with a common denominator:
y = 4(x - (3/8))² - (16/16 + 9/16)
Combine the constant terms and simplify:
y = 4(x - (3/8))² - 25/16
Therefore, the vertex form of the quadratic function y = 4x² - 3x - 1 is y = 4(x - (3/8))² - 25/16, and the vertex is at the point (3/8, -25/16).
