The verticies of J’K’L would be, J'(-a, -b), K'(-c, -d), and L'(-e, -f).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, Triangle JKL is rotated 180 about the origin, resulting in triangle J’K’L.
Assuming the coordinates of J(a, b), K(c, d) and L(e, f).
We know a rotation of 180° to (x , y) ⇒ (- x, - y).
Therefore, The vertices of J’K’L would be, J'(-a, -b), K'(-c, -d), and L'(-e, -f).

Alexander’s parents are saving for his college fund. They put $8,000 into an interest-bearing account with an annual compound interest rate of 4.5%.
Alexander’s parents want to determine what the balance of his college fund account will be after 12 years.
Which formula would be used for this situation?
A = (8,000 + 0.045)12
A = 8,000(1 + 0.045)12
A = 8,000(1 + 0.12)4.5
A = 8,000 · 0.045 · 12
Answer:
a=8,000(1+0.12)4.5

The average number of employees that call in sick for the day over the course of a year is 25. The number of employees that call in sick on 12 days are 25, 10, 16, 39, 27, 25, 32, 25, 25, 22, 28 , and 14 Enter the sample mean and the population mean.
Answer:
it depends on the work place to play it safe i would choose 12
Step-by-step explanation:
The sample mean is equal to 24 and population mean is equal to 25
What is sample mean?Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.
Sample mean= sum of the terms/number of the terms
What is population?
The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.
Population mean= sum of the population/ number of the population
From the given question average of entire year is 25.
According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.
According to the sample mean formula,
sample mean= sum of the terms / number of the terms
⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24
Thus the sample mean is equal to 24 and population mean is equal to 25

Step 1: Substitute the x and y values:
[tex]\frac{4^3-2^3}{4}[/tex]
Step 2: Find 4 to the power of 3.
4 x 4 x 4 = 64
Now find 2 to the power of 3
2 x 2 x 2 = 8
Step 3: Subtract the two values as mentioned in the equation:
64 - 8 = 56
Step 4: Now divide 56 by 4 as mentioned in the equation.
56 ÷ 4 = 14

Step-by-step explanation:
A football player attempts to kick a football across a field. The path of the football can be modeled by the function h(x) = − 1/225 x^2 + 2/3 x, where x is the horizontal distance from the kick, and h(x) is the height of the football above the ground, when both are measured in feet. How far from the kicker will the football land?
The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.
Answer:
The toy reaches the ground in 10 sec
Step-by-step explanation:
When the rocket hits the ground, h becomes zero (0). Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,
Because of the fractional coefficient -4.9, it's best to use the quadratic equation here. The coefficients of the t terms are {-4.9, 50, 2}. Thus,
the discriminant is b^2 - 4ac = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.
The quadratic formula is as follows:
-b ± √discriminant
t = -------------------------------
2a
which here is:
-50 ± 50.39
t = ------------------------ Since t represents time, only the positive result
-9.8 is relevant here; it is 10.24 sec,
which rounds off to 10 sec
The toy reaches the ground in 10 sec

Find the Area of the shape
(Area of Composite Shapes)
Answer:
223.5 Km
Step-by-step explanation:
Area = Length x Width
Solving for Square Shape
8 · 6 = 48 km
Area = Length x Width
Solving for Rectangle Shape
9 · 14 = 126 km
Area = Length x Width ÷ 2
Solving for Triangle Shape
11 · 9 = 99 ÷ 2 = 49.5 Km
48 + 126 + 49.5 = 223.5 Km

1/3 x 2. Since this equation does not have one x but 2 (x and y), we will not subtract or divide any sides.
Divide and multiply 2 by 8 and 1/3. Then, we solve for y.

How many lines of symmetry are in a regular polygon?
seven
twice as many as the number of sides
half as many as the number of sides
the same number as the number of sides
Answer:
the same number as the number of sides
lines of symmetry are in a regular polygon is the same number as the number of sides.
the correct option is (D)
What is Line of symmetry?A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly.
The number of lines of symmetry in a regular polygon is equal to the number of sides.
For example,
It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry.
Hence, lines of symmetry in a regular polygon is equal to the number of sides.
