What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that,
Given coordinates,
L(7,−2), M(6,−4), N(3,−7), and P(2,−3)
From the given condition Quadrilateral LMNP is reflected across the x-axis and then translated 8 units left to form quadrilateral L′M′N′P′.
The coordinates of quadrilateral L′M′N′P′ are found as,
L(7-8,−2), M(6-8,−4), N(3-8,−7), and P(2-8,−3)
L′(−1,−2), M′(−2,−4), N′(−5,−7), and P′(−6,−3).
Thus, the coordinates of quadrilateral L′M′N′P′ will be L′(−1,−2), M′(−2,−4), N′(−5,−7), and P′(−6,−3).

Use the function rule \(f\)(x)=3\(x\)-2. Find the output \(f\)(1.5).
Answers
Answer:
To find the output of the function f(x) = 3x - 2 when x = 1.5, we simply substitute 1.5 for x in the function rule and simplify:
f(1.5) = 3(1.5) - 2
f(1.5) = 4.5 - 2
f(1.5) = 2.5
Therefore, the output of the function f(x) when x = 1.5 is 2.5.
Answer:
f(x)- x = 1.5 is 2.5.

The ratio of keepers to animals in the city zoo is 2 : 7. 12 keepers and 42 animals. If 21 more animals are added, how many total keepers are needed to maintain the ratio of keepers to animals?
A. 16
B. 17
C. 18
D. 19
E. 20
Answers
Answer:
C: 18
Step-by-step explanation:
All you have to do is write down the ratio. Then you find out that 21 is half of 42 so that means that the amount of zookeepers that you will have to add should be half the amount as well so instead of 12 it would be 6. Then you just add the two numbers together to get your final answer of 18.
The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

The radius of a cylinder is (3x-2cm). The height of the cylinder is (x+3cm).
What is the surface area of the cylinder?
Use the formula A=2\pi r^(2)+2\pi rh.
Answers
Answer:
\((24\pi x^2-10\pi x-4\pi)\) square centimeters
Explanation:
Let
\(r=\text{radius of the cylinder}=3x-2 < br/ >\)
\(h=\text{height of the cylinder}=x+3\)
Then the surface area of the cylinder is given by
\(A=2\pi r^2+2\pi rh\)
\(=2\pi r(r+h)\)
\(=2\pi (3x-2)((3x-2)+(x+3))\)
\(=2\pi (3x-2)(4x+1)\)
\(=2\pi(12x^2-5x-2)\)
\(\boxed{A=(24\pi x^2-10\pi x-4\pi )cm^2}\)

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

interest earned = $200
so $200 = $800 * x /100* 24/12
200 = 800 * x/100 * 2
