Answer: rotation can be expressed as the composition of two reflections. A composition of reflections over two parallel lines is equivalent to a translation. Example: Given a || b, and pre-image ΔABC, where parallel lines are vertical. The composition of reflections over two intersecting lines is equivalent to a rotation. A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines). i hope this helps.

Answer:
∠EGA = 123°
∠EHD = 57°
Step-by-step explanation:
Determine the measure of ∠EGA:
Since ∠EGB and ∠EGA make up the angle of a straight line (180°):
∠EGB+∠EGA = 180
57+∠EGA = 180 (given that ∠EGB = 57°)
∠EGA = 123°
Determine the measure of ∠EHD:
∠EHD = ∠EGB (corresponding angles of parallel lines are equal)
∠EHD = 57° (given that ∠EGB = 57°)

a) Work out the rate of change during the first 4 seconds.
b) Work out the rate of change between 8 seconds and 12 seconds.
Answer:
a. 37.5
b. 25
Step-by-step explanation:
a. Rate of change the first 4 seconds can be calculated using the points (0, 0) and (4, 150):
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{150 - 0}{4 - 0} = \frac{150}{4} = 37.5 [/tex]
b. Rate of change between 8 seconds and 12 seconds using the points (8, 150) and (12, 250):
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{250 - 150}{12 - 8} = \frac{100}{4} = 25 [/tex]
Which expression is equivalent to 3n+2(1-4n)?
A. 2-n
B. 2-5n

which expression is equivalent to 2cos2(x/2)-cos(x)
The expression that is equivalent to 2cos²(x/2) - cos(x) is 1.
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.
Here,
We can use the double angle identity for cosine, which states that:
cos(2θ) = 2cos²(θ) - 1
To simplify given expression expression by putting cos(x) = 2cos²(x/2) - 1 as follows:
= 2cos²(x/2) - cos(x)
= 2cos²(x/2) - 2cos²(x/2) + 1 (using the identity cos(2θ) = 2cos²(θ) - 1)
= 1
Therefore, the expression that is equivalent to 2cos²(x/2) - cos(x) is 1.

Complete Question
The horizontal axis in the sampling distribution of [tex]\^p[/tex] represents all possible sample proportions from a simple random sample of size n.
a. What percent of sample proportions results in a 90% confidence interval that includes the population proportion?
b. What percent of sample proportions results in a 90% confidence interval that does not include the population proportion?
Answer:
a
90% of all possible sample proportions
b
(100% - 90% = 10% ) of all possible sample proportions
Step-by-step explanation:
Generally given from the question that the horizontal axis of a represent all possible sample proportion then then the percent of the sample proportion that result in 90% interval that includes the population proportion is 90% of all possible sample proportions
Generally given from the question that the horizontal axis of a represent all possible sample proportion then the percent of the sample proportion that result in 90% interval that does not include the population proportion is (100% - 90% = 10% ) of all possible sample proportions

The function h(x) is graphed on the coordinate plane provided. Determine the statements that are true about the function h(x). Select the two correct answers. The slope is -2. The slope is 1/2. The y-intercept is 1/2. The y-intercept is -4 . The x-intercept is 4.
Answer:
so you will need the slope is 1/2 and the y intercept is -4
Step-by-step explanation:
just find the y coordinate and find where the line on the graph is located to find the intercept then the slope is just where and how much the graph moves to for example if the graph goes right 2 times it goes up once so that means that it is true
cuanto es la Raiz cuadrada de 12
The square root of 12 is approximately 3.4641.
The square root of 12 is an irrational number, meaning it cannot be expressed as a fraction or terminating decimal. However, we can approximate its value.
To approximate the square root of 12, we can use a calculator or perform an estimation. The square root of 12 is approximately 3.4641.
When we multiply 3.4641 by itself (3.4641 * 3.4641), we get a value very close to 12, but not exactly 12 due to the irrational nature of the square root.
The square root of 12 represents a number that, when multiplied by itself, equals 12. It is a non-repeating, non-terminating decimal that goes on infinitely. The approximation 3.4641 is commonly used to represent the square root of 12 in practical calculations.
