The transformation that does NOT preserve congruence is C, a dilation by a scale factor of 5.
Therefore the answer is C.
Dilations change the size of a figure, but do not preserve its shape or angles, so congruence is not guaranteed to be preserved. A dilation stretches or shrinks a figure by a certain scale factor, while keeping its center fixed. Since the new figure is not the same size or shape as the original, it is not congruent to the original. In contrast, reflections, translations, and rotations all preserve shape and size, so they do preserve congruence. Therefore the answer is C) A dilation by a scale factor of 5.

Federico makes 60% of the free throw shots he takes in basketball. Federico is fouled, and he is in a one-and-one shooting situation meaning that he only gets a second free throw shot if he makes his first one. Each free throw shot is worth one point. What is the probability that Federico scores one point in this situation?
Answer:
So the probability that Federico scores one point in this situation is 84%.
Step-by-step explanation:
The probability that Federico makes his first shot is 60%, so the probability that he misses it is 40%. If he misses his first shot, he doesn't get a second one, so the probability of scoring one point in this situation is the probability of making the first shot (60%) plus the probability of missing the first shot and making the second one (40% x 60%), which is:
0.60 + 0.24 = 0.84
So the probability that Federico scores one point in this situation is 84%.

Find the lengths of g, h, and j. Round answers to the nearest tenth.
The sides of the given right triangle are:
g = 33.80
h = 31.20
j = 13
What is a triangle?
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total. Any three points in Euclidean geometry, when they are not collinear, produce a distinct triangle. A right triangle is a triangle with two perpendicular sides and one angle that is a right angle.
The given figure has a large right triangle with sides g,h and j and a small right triangle with sides 12, j and 5.
Using the small triangle, we can find the value of j.
By Pythagoras theorem,
j² = 12² + 5² = 144 + 25 = 169
j = 13
Now using trigonometric relation we can find the angle ∅ between j and 5.
sin ∅ = 12/13 = 0.923
∅ = sin ⁻¹ (0.923) = 67.37°
This angle is common for both triangles.
So for large triangle,
tan 67.37 = h/j = h/13
2.4 = h/13
h = 31.2
By Pythagoras theorem,
g² = h² + j² = 31.2² + 13² = 1142.44
g = 33.8
Therefore the sides of the given right triangle are:
g = 33.80
h = 31.20
j = 13.

the reflection of the given function will be f(-x) = 0.5 4⁻ˣ and the graph of this function is attached below.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Given, a function as shown in the graph:
To reflect a function over the y-axis we use the rule:
f(-x) reflects the graph of f(x) over the y-axis. In other words, to reflect f(x) over the y-axis, we just need to replace x with -x.
Let's find f(x) first using the standard exponential growth function:
f(x) = a( 1 + b )ˣ
From our graph, we can infer that f(x) = 1/2 when x =0, so let's replace those values in our function:
f(x) = a( 1 + b )ˣ
1/2 = a(1 +b)⁰
a = 1/2
We can also infer that f(x) = 8 when x =2. Since we already know that a = 1/2, let's replace the values to find and complete our function:
f(x) = a( 1 + b )ˣ
8 = 1/2(1 +b)²
4 = 1+b
b = 3
So putting it all together:
f(x) = 1/2( 1 + 3 )ˣ
Finally, we can apply the reflection rule to find the reflection over the y-axis:
f(-x) = 1/2(4)⁻ˣ
f(-x) = 0.5 4⁻ˣ

A rectangle of 24 1/2 sqaure feet if the length of the rectangle is 4 3/8 feet, and the width of the rectangle is 4 feet.
What is the area of the rectangle?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
To find the width of the rectangle, we can use the formula for the area of a rectangle:
Area = Length x Width
We are given that the area of the rectangle is 24 1/2 square feet and the length is 4 3/8 feet. Substituting these values into the formula, we get:
24 1/2 = 4 3/8 x Width
To solve for the width, we can first convert both mixed numbers to improper fractions:
24 1/2 = 49/2
4 3/8 = 35/8
Substituting these values, we get:
49/2 = 35/8 x Width
To solve for Width, we can cross-multiply:
49/2 * 8/35 = Width
Simplifying, we get:
4 = Width
Therefore, the width of the rectangle is 4 feet.

The area of a rectangular room in 150 square feet. If the length of one side of the room is 11feet, what is the perimeter of the room?
The perimeter of the room is approximately 49.272 feet.If the area of a rectangular room is 150 square feet, and one side of the room is 11 feet, we can find the length of the other side by dividing the area by the length of the known side:
Length × Width = Area
Width = Area ÷ Length
Width = 150 ÷ 11
Width ≈ 13.636 feet
Now that we know the length and width of the room, we can calculate the perimeter by adding up the length of all four sides:
Perimeter = 2 × Length + 2 × Width
Perimeter = 2 × 11 + 2 × 13.636
Perimeter ≈ 49.272 feet

In an effort to improve scores on college-entrance exams, the principal at a large high school chooses 35 students at random who have already taken the exam. The students are enrolled in a six-week prep course to improve their scores. After the prep course, the students take the college-entrance exam again. The mean difference (first – second) in exam scores is –1.75 points with a standard deviation of 7.12 points. Assuming the conditions for inference are met, what is the P-value for testing the hypotheses H0 :μdiff = 0; Ha :μdiff > 0? Find the t-table here.
For testing the hypotheses H0: μdiff = 0; Ha: μdiff > 0, the P-value is 0.6294.
We have,
The hypotheses are as follows:
Null Hypothesis (H0): The mean difference in exam scores is equal to 0. μdiff = 0
Alternative Hypothesis (Ha): The mean difference in exam scores is greater than 0. μdiff > 0
To calculate the t-statistic, we use the formula:
t = (x - μ) / (s / √n)
Where:
x is the sample mean difference (given as -1.75)
μ is the hypothesized population mean difference under the null hypothesis (0 in this case)
s is the sample standard deviation (given as 7.12)
n is the sample size (given as 35)
Substitute the given values:
t = (-1.75 - 0) / (7.12 / √35)
t ≈ -0.33071
The degrees of freedom (df) for the t-distribution.
The degrees of freedom for this test is equal to the sample size minus 1:
df = 35 - 1 = 34
The P-value is associated with the calculated t-statistic.
Since we are testing for a one-sided alternative (μdiff > 0), we need to find the area under the t-distribution curve to the right of the t-statistic.
Using the t-table, with df = 34 and t ≈ -0.33071, we find the P-value to be approximately 0.6294.

Bonjour !
Pour obtenir la deuxième ligne de l'équation que vous avez donnée, on peut tout simplement développer le terme Un+1 en utilisant la définition de Un+1 donnée par la relation de récurrence :
Un+1 = 2Un + 1/3(n+1)
En remplaçant Un+1 dans l'expression Un+1 - Un, on obtient :
Un+1 - Un = (2Un + 1/3(n+1)) - Un
On simplifie l'expression en combinant les termes similaires :
Un+1 - Un = 2Un - Un + 1/3(n+1)
Un+1 - Un = Un + 1/3(n+1)
Maintenant, pour obtenir la troisième ligne de l'équation, on peut factoriser Un - Un+1 en utilisant le signe moins :
Un - Un+1 = - (Un+1 - Un)
Un - Un+1 = - (Un+1 - 2Un - 1/3(n+1))
Un - Un+1 = - (-2Un - Un+1 - 1/3(n+1))
Un - Un+1 = 2/3Un + 1/3(n+1) - 1/3Un - 2/3Un - 1/3(n+1)
On simplifie à nouveau en combinant les termes similaires :
Un - Un+1 = -1/3Un + 1/3(n+1)
Enfin, pour obtenir la quatrième ligne de l'équation, on utilise l'associativité de l'addition pour regrouper les termes :
Un - Un+1 = -1/3Un + 1/3(n+1)
Un - Un+1 = 1/3(n+1) - 1/3Un
Un - Un+1 = 1/3(n+3 - Un)

a 25 foot ladder is leaned against the side of a building 2 feet from the base of the building. how far up the wall does the ladder reach and what is the angle of elevation for the ladder both to the nearest tenth?
Answer:
The ladder reaches up to 23.2 feet up the side of the building and the angle of elevation is 78.7 degrees to the nearest tenth. To calculate these values, you can use the Pythagorean Theorem. Let x be the distance the ladder reaches up the wall, and let y be the distance from the base of the building to where the ladder is leaning against the wall. Then, the Pythagorean Theorem states that x2 + y2 = 252, or x2 = 252 - y2. Since y = 2, then x2 = 252 - 22 = 676. Solving for x gives us x = 26, so the ladder reaches up to 26 feet. To calculate the angle of elevation, we can use trigonometry. We know that the opposite side is 26 feet and the adjacent side is 2 feet, so by using the tangent function, we can calculate the angle of elevation as tan-1(26/2) = 78.7 degrees.
