A. Translation
This type of translation is defined as moving the object in space by keeping its size, shape or orientation constant. In a translation, each point of the shape must be moved in the same direction and for the same distance. When you are doing a translation, the primary object is called the pre-image, and the object after the translation is called the image.
B. Rotation
This type of transformation has an object about a fixed point without changing its size or shape.
C. Reflection
A reflection is a transformation that reflects each point in the preimage across a line of reflection. It is a rigid motion so it preserves length and angle measure
A perpendicular bisector is a line (ray, segment) which cuts a line segment into two equal parts at90° angle
D. A transformation is a change in the position or size of an object Movements that do not change the size or shape of the object moved are called “rigid transformations” There are three types of rigid transformations: Translations, Reflections, and Rotations. These are more commonly referred to as Slides, Flips, and Turns.

What are the coordinates of the focus of the parabola? (0,2) (0,–2) (2,0) (–2,0)
Answers
The focus of the parabola is at the point (0, 2).
What is the focus of the parabola?A parabola's focus can be found on the side of the concavity, at the same distance from the vertex as from the directrix, and at the same distance from the vertex to the parabola's centre of gravity.
This is actually a great geometrical characteristic of the parabola and the way it may be built using its definition. all those lane sites whose distance from the directrix to the focus is equal.
Then, the focus must be at a distance of two units from the vertex, (0,0), in line with the parabola's axis of symmetry (x=0), and on the positive side of the y-axis (notice the directrix is on the negative side of the y-axis.
So, the focus of this parabola at the point (0, 2).

Alex wants to pay off his credit card balance before he gets married. he decides to take the $2,300 out of his savings and apply it to his credit card debt of $5,390. the credit card has an apr of 16.5%. what will alex's minimum monthly credit card payment be in order to pay off his debt in 14 months? a. $109.40 b. $190.83 c. $244.15 d. $572.32
Answers
Answer:
I think C!
Step-by-step explanation:
I just took the test.
Alex's minimum monthly credit card payment will be $244.15.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Firstly calculate the remaining credit card balance after Alex applies his savings:
$5,390 - $2,300 = $3,090.
Calculate the monthly interest rate on the credit card: 16.5% / 12 = 0.01375.
Use the formula P = i / (1 - (1+r)⁻ⁿ) to calculate the minimum monthly payment.
i = the remaining balance = $3,090
r = the monthly interest rate = 0.01375
n = the number of months to pay off the balance = 14
Plugging in the values, we get:
P = 3090×(0.01375)/(1-(1+0.01375)⁻¹⁴)
= $244.15
Therefore, Alex's minimum monthly credit card payment will be $244.15.

Find the volume for the regular pyramid.
V=
Answers
Answer:
Step-by-step explanation:
First is to find area of base triangle:
It is an equilateral triangle with one side at 4
Height is given by 4*sin60degree = 2*sqrt(3)
Area = 1/2 * side * height
= 1/2*2*sqrt(3)*4
= 4*sqrt(3)
Height of pyramid is at centroid of the base equilateral triangle
Length of angle bisector of the base equilateral triangle
= sqrt(4^2 - 2^2)
= sqrt(16-4)
= sqrt(12)
Centroid is at sqrt(12)/3 from the nearest side.
Consider right-angle triangle formed by top of pyramid and centroid:
Height^2 + (sqrt(12)/3)^2 = 4^2 - 2^2
Height^2 = 16 - 12 - 12/9 = 24/9
Height = (2/3)*sqrt(6)
Volume of pyramid = 1/3*base area*height
= 1/3*4*sqrt(3)*(2/3)*sqrt(6)
= (8/3)*sqrt(2)
= 3.77

Answers
Answer:
a) There are 9 outcomes.
b) **i have attached the tree diagram**
c) 1/9
d) 1/9
Step-by-step explanation:
Both events (choosing a shirt and choosing pants) are not mutually exclusive (disjoint). Meaning that both events can occur at the same time.
a) For a sequence of two events in which the first event can occur m ways and the second event can occur n ways, the events together can occur a total of m • n ways. So for this problem, you would do 3 • 3 which equals 9.
b) **tree diagram is attached**
c) Because there are two different events occurring (choosing a shirt and choosing pants) you need to multiply using the Multiplication Rule for Independent Events : P(A and B) = P(A) * P(B)
The probability of event A occurring (choosing a red shirt) is 1/3 and the probability of event B occurring (choosing brown pants) is also 1/3.
1/3 * 1/3 = 1/9
d) You would do the same thing here as part c.
The probability of event A occurring (choosing a blue shirt) is 1/3 and the probability of event B occurring (choosing blue pants) is again 1/3.
1/3 * 1/3 = 1/9

What expression represents the width of the rectangle
Answers
We are given a rectangle with one of its sides ( length ) equal to ( x - 7 ) Meters.
Also we are given the area of the rectangle as x² - 15x + 56 square meters .We have to find the expression for another side of the rectangle i.e it's width
We will use the formula of area of rectangle to find the expression :
Area = length × widthTherefore,
ㅤㅤ➝ A = l × w
ㅤㅤ➝ x² - 15x + 56 = ( x - 7 ) × w
ㅤㅤ➝ x² - 8x -7x + 56 = ( x - 7 ) × w
ㅤㅤ➝ (x² - 8x )( - 7x + 56 ) = ( x-7 ) w
ㅤㅤ➝ x( x - 8 )-7( x - 8 ) = ( x - 7 )w
ㅤㅤ➝ ( x - 8 )( x - 7 ) = ( x - 7 )
ㅤㅤ➝ ( x - 8 )w = ( x - 8 )( x - 7 )
ㅤㅤ➝ w = ( x - 8 )( x - 7 ) / ( x - 7 )
ㅤㅤ➝ w = ( x - 8 )

Answers
Answer: Answer below
Step-by-step explanation:
We start off by subtracting 120 from 150, since we want to find the amount it decreased and not what percentage is left.
150 - 120 = 30
We now divide it by 150 to get our percentage.
30/150 = 1/5
1/5 = 0.2 or 20%
Our answer is 20%.

Henry deposited $250 into a savings account that earns 1.9% simple interest. How much will his account be worth at the end of 10 years?
Answers
Answer:
$297.5
Step-by-step explanation:
I = Prt/100
I = Interest
P = Amount deposited initially
r = Rate
t = number of years
I = Prt/100
= 250 × 1.9 × 10 / 100
= 25 × 1.9
= 47.5
That is the interest
The total amount in his account will be Initial amount + interest
250 + 47.5
= $297.5

Step-by-step explanation:
Alice can select any ball from her bag and it goes into Bob's bag. Then bob has 6 balls including two of one color.
Suppose they are {A,B,B,C,D,E}

John gave half of his stamps to Jim. Jim gave half of his stamps to Carla. Carla gave 1/4 of the stamps given to her to Thomas and kept the remaining 12. How many stamps did John start with?
Answers
Answer: 64 stamps
Step-by-step explanation:
Let the number of stamps John started with be J.
After giving half to Jim, he would have J/2 left.
After giving half to Carla he would have J/4 left and Carla would also have J/4.
After Carla gave 1/4 to Thomas, she would keep (3/4)*(J/4) = 3J/16 stamps. We are given that this equals 12.
Therefore, 3J/16 = 12
Multiply both sides by 16:
3J = 192
Divide both sides by 3:
J = 64

x² + 6x = 7
Answer:
Answer:
The first step to solve the equation by completing the square 3x²+ 18x= 21 is multiply both sides of the equation by .
The factors of the equations 3x²+ 18x= 21 are 1 ,-7 .
Step-by-step explanation:
As given the equations
3x² + 18x = 21
Multiply both sides of the equation by .
Thus the equation becomes
Simplify the above
x² + 6x = 7
Adding 9 on both sides of the above equation
x² + 6x + 9 = 7 + 9
x² + 6x + 9 = 16
(As (a +b)² = a² + b² + 2ab
Thus (x+3)² = x² + 6x + 9 )
Put in the above
(x+3)² = 16
Taking square root on both side
√16 = ± 4
First take
(x + 3) = 4
x = 4 -3
x = 1
Second take
(x+ 3) = -4
x = - 4 -3
x = -7
Therefore the first step to solve the equation by completing the square 3x²+ 18x= 21 is multiply both sides of the equation by .
The factors of the equations 3x²+ 18x= 21 are 1 ,-7 .
