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.

When solving this equation for x, what would you do next?
Answer: A. Distribute the 3 outside of the parathesis to everything inside the parenthesis
We use the order of operations, also known as PEMDAS.
Since there is a variable inside the parenthesis, we cannot add/subtract 4. This means the next step is to distribute.
After distributing, the equation looks like this and we can solve it from there:
4x + 12 = 30
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.

Explain how you would find the perimeter of this triangle.
Answer:
Step-by-step explanation:
51+90=141.3
180-141.3=38.7
90+38.7+51.3
So 4 and a number equal 90 degrees.
51.3 degrees are the number of 4 and c^2
We can use the Pythagorean theorem to find out that a^2 is 16
16 and b^2 will equal c^2 or the missing angle for 51.3 degrees.
a=51.3
b=90 meaning it has a 38.7 more of an angle than the 4 on the bottom.
Meaning it will be 7.02
7.02+4=11.02

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?

a_n is n the terma is first termr is common ration is an positive integerA person sold a desk for rs. 400 and incurred a loss of 5%
approximately at what price would it be sold so as to earn
a profit of 6%?
a) 420
b)478
c)446
d)432
Answer: C
Step-by-step explanation:
1% of Rs. 400 = 4
10% of Rs.400 = 40
5%= 20
400+20= Rs. 420 was the price the person may have bought it for
To get a 6% profit, we need to add 6% on top of the price the chair was bought for by the owner
so...
420+ 5% +1%
so..
420+20+4= 444

The function P(x)=2x+1 is dilated by the function I(x)=1/2P(x). Which function rule represents I(x)?
We will see that we can write the function I(x) as:
I(x) = x + 1/2.
How to get the function I(x)?
We know that I(x) is a vertical dilation of scale factor 1/2 of P(x), where:
P(x) = 2x + 1.
The vertical dilation will be written as:
I(x) = (1/2)*P(x).
If we replace P(x) by the actual function, we will get:
I(x) = (1/2)*(2x + 1) = x + 1/2.
Then we can conclude that the function I(x) is:
I(x) = x + 1/2.

The length of a rectangle is eight more than triple the width. If the perimeter is 168 inches, find the dimensions.
Answer:
P= 2(3W + 7) + 2(W) = 110.
P= 6W + 14 + 2W = 110.
= 8W + 14 = 110.
= 8W = 110 - 14 = 96
W = 96/8 = 12- inches.
Now solve for (L) by L = 3W + 7 = 3(12) + 7 = 36 + 7 = 43- inches

The width of the rectangle is 12 inches and the length is 43 inches.
What is the perimeter?
The perimeter is defined as the sum of all the sides of the figure. It is given that the length of a rectangle is eight more than triple the width and the perimeter is 168 inches.
The length and the width are calculated as:-
P= 2(3W + 7) + 2(W) = 110.
6W + 14 + 2W = 110.
8W + 14 = 110.
8W = 110 - 14 = 96
W = 96/8 = 12 inches.
Now solve for (L) by
L = 3W + 7 = 3(12) + 7
L = 36 + 7 = 43 inches
Hence, the width is 12 inches and the length is 43 inches.

The student used additive commutative property for the first step.
What is an additive commutative property?According to this property, when two numbers or integers are added, the sum remains the same even if we change the order of numbers/integers. This property is also applicable in the case of multiplication. It can be represented as; a + b = b + a.
The student used a + b = b + a
3a + b = 2 + 7 - 5a = 2 - 5a + 7
Because add two numbers, exchange the position of the addend, and sum of them remain same.
This is a additive commutative property.
