Which is the BEST definition of dilation?
A. a transformation that either reduces or enlarges an object in the coordinate plane
B. a transformation that flips an object in the coordinate plane
C. a transformation that spins an object in the coordinate plane
D. a transformation that either slides or shifts an object in the coordinate plane
Answer:
A. a transformation that either reduces or enlarges an object in the coordinate plane
Step-by-step explanation:
The definition of dilation is the size of an object/shape by increasing/ decreasing its dimensions by scaling factors.
Dialtions do not flip and object, spin it, or slide it. It's dimensions are either enlarged, or reduced. Therefore, option A makes the most sense.

Answer:
Kiko was right.
Step-by-step explanation:
When a positive integer is multiplied by another positive integer, the product is positive. When a negative integer is multiplied by a positive integer, then the product is negative. The power should also be considered as well, since it can affect whether the integer is positive or negative depending on if it's even or odd.

Tara found a pair of jeans that were regularly priced at $35. She has a coupon for 15% off. What is the price of the jeans after applying the coupon?
$20
$7
$29.75
$33.50
Answer:
The price is $29.75
Step-by-step explanation:
Because it is 15 percent off, that means that the jeans are priced at 100%-15%=85%. To convert a percent to a decimal, move the decimal two places to the left. This gives us .85. Multiply 35 by .85 and you will get 29.75. Hope this helps!

Given Question
For the expression [tex]2x-5[/tex], evaluate it for [tex]x = (0, 1, 2, 3, 4, 5)[/tex].
From the evaluated set of values the mean absolute deviation rounded off to the nearest tenth is:
-------------------------------------------------------------------------------------------------------
Evaluating the expression for the given values of x:
[tex]x=0 \implies 2(0)-5=-5[/tex]
[tex]x=1 \implies 2(1)-5=-3[/tex]
[tex]x=2 \implies 2(2)-5=-1[/tex]
[tex]x=3 \implies 2(3)-5=1[/tex]
[tex]x=4 \implies 2(4)-5=3[/tex]
[tex]x=5 \implies 2(5)-5=5[/tex]
Evaluated set of values: -5, -3, -1, 1, 3, 5
To find the Mean Absolute Deviation (MAD):
Calculate the mean (by summing the data values and dividing by the number of values)Subtract the mean from each value in the data set and take the absolute value of each result.Sum the absolute values from step 2.Divide by the number of values.[tex]\sf Mean=\dfrac{(-5)+(-3)+(-1)+1+3+5}{6}=0[/tex]
Absolute values:
[tex]\sf|-5-0|=5[/tex]
[tex]\sf|-3-0|=3[/tex]
[tex]\sf|-1-0|=1[/tex]
[tex]\sf|1-0|=1[/tex]

Ramesh lent a loan of Rs 1800 to Suresh at a rate of interest for 2 years. At the end of period Suresh refunded him a total of Rs 2232. At what rate of interest had Ramesh lent the loan? Ans: 12%
Answer:
12%
Step-by-step explanation:
Simple interest formula: A = P(1 + rt)
where:
A = final amountP = principalr = interest rate (in decimal form)t = time (in years)Given:
A = Rs 2232P = 1800t = 2Substitute given values into the formula and solve for r:
⇒ A = P(1 + rt)
⇒ 2232 = 1800(1 + r · 2)
⇒ 1.24 = 1 + r · 2
⇒ 0.24 = 2r
⇒ r = 0.12
Convert into percentage:
0.12 = 12/100 = 12%

D) x = 20
Step-by-step explanation:
Theorem
The sum of the interior angles of a triangle is 180°
Solution
Add the angles and equate to 180:
⇒ (x + 5) + (7x - 5) + x = 180
Collect like terms:
⇒ x + 7x + x + 5 - 5 = 180
Combine like terms:
⇒ 9x = 180
Divide both sides by 9:
⇒ x = 20

How do you recognize a geometric sequence? Can you find terms within a geometric sequence using a formula?
Answer:
See step by step explanation
Step-by-step explanation:
To reconize a geometric sequence, the factor at which one number is greater than the previous number should always be the same
For example,
2,4,8,16,32,64,128,256,512,1024 is a geometric sequence since the next number is always greater than the previous number by a factor of 2
to find the n-th term in a sequence, we can use a formula.
Going back to the example, let's label each number with a term
to find the nth term of this specific sequence, we need to find two things
the first number of the sequence, and the factor at which this sequence increases at
the first number is 2, so n1 = 2
each term increases by a factor of 2 (2*2=4, 4*2=8, 8*2=16, 16*2=32, 32*2=64), so the factor is 2
the equation is:
(the initial term)*(the factor)^(the term number - 1)
so,
[tex]2*2^{n-1}[/tex] is our equation
We can check our equation by plugging in a number
looking back at our list, we see that the 7th term is 128
plug in 7 into out equation
[tex]2*2^{7-1}=2*2^6=2^1*2^6=2^7=128[/tex], so our equation works
Here's a practice problem
for the sequence 3,9,27,81,243,729, what is the factor which the sequence increases at? what's the initial number? what's the equation for this sequence?
a harder practice problem:
for the sequence 2,6,18,54,162,486, what is the factor at which the sequence increases at? what's the intitial number? what's the equation for this sequence? what's the 8th term of this sequence if it were to be continued?
Yes we can
the formula given to find the terms is
a_n=ar^n-1Where
a_n is n the terma is first termr is common ration is an positive integerA bag has six balls labeled a,b,c,d.e and f . One ball will be randomly picked, and its letter will be recorded as the outcome. Give the sample space describing all possible outcomes. Then give all of the outcomes for the event of choosing the letter b,e or c . If there is more than one element in the set, separate them with commas.
Answer:
Step-by-step explanation:
given that a bag contains 6 balls labelled A to F.
Given that a ball is drawn at random and its letter is recorded as outcome.
Since each ball is equally likely to be drawn the sample space for one ball drawing is
S = {A,B,C,D,E,F} and n(S) = 6
Let G be the event of choosing a lable from D to F
G = The event of choosing a label from D to F= {D,E,F} n(A) = 3
A sample space is a set which contains the set of all the possible outcomes or results that could occur while performing an experiment.
i.e. the sample space while flipping a coin is: {H,T}
The sample space while tossing a six-sided die is: {1,2,3,4,5,6}
Here it is given that:
A bag has six balls labeled: A,B,C,D,E,F
One ball will be randomly picked, and its letter will be recorded as the outcome.
This means that the sample space is given by:
Sample space={ A,B,C,D,E,F}
Now, when the event is choosing a letter from D to F.
Then the sample space is:
Sample space= {D,E,F}

The vertices of a rectangle are W(1,2), X(4,2), 7(4, -3), and Z(1, -3). Find the perimeter of the
rectangle. Use words, numbers, or models to justify your answer.
Answer:
16
Step-by-step explanation:
We could use the distance formula to find the distance between the points in this problem, but when we look we see that the sides of the rectangle are parallel to the x and y-axis for each pair of sides. The first two points have a distance of 3 because 4-1=3. Since it is a rectangle, the opposite side will have the same length. For the sides perpendicular, we look at the points with the same x coordinate. Using (4,2) and (4,-3), we can calculate the length of the side by finding the distance by adding the absolute values of the y coordinate. 2+3=5. This means that the triangle has two sides with a length of 5 and two sides with a length of 3. Adding these together, 5+5+3+3 = 16.

Each face of a cube has an area of 4 square units. What is the volume of the cube?
Each face of a cube has an area of 4 square units, then the volume of the cube is 8 cubic units.
The given information states that each face of the cube has an area of 4 square units.
Since a cube has 6 faces, this means that the total surface area of the cube is:
Total Surface Area = 6 * 4 square units = 24 square units
Now, let's relate the surface area of the cube to its volume:
For a cube, the surface area (S) and the volume (V) are related by the formula:
S = 6s²
Where "s" is the length of each side of the cube. In this case, we have:
S = 24 square units
Substitute this into the formula:
24 = 6s²
Now, solve for "s":
s² = 24 / 6
s² = 4
Take the square root of both sides:
s = √4
s = 2
So, each side of the cube is 2 units long.
Now, to find the volume of the cube, you can use the formula for the volume of a cube:
V = s³
Substitute the value of "s":
V = 2³
V = 8 cubic units
Therefore, the volume of the cube is 8 cubic units.

y = -3x -2
Step-by-step explanation:
The equation of the given line, with slope -3 and y-intercept 4, can be written in slope-intercept form as ...
y = -3x +4
When the line is translated by (h, k), it can be written as ...
(y -k) = -3(x -h) +4

Here, we want to translate the line -4 in the x-direction and 6 in the y-direction. That is, (h, k) = (-4, 6). Using these values in the above equation, we have ...
y -6 = -3(x -(-4)) +4
