Figure ABCD is a rectangle with point A (−2, 5). What rule would rotate the figure 90° clockwise?
A. (x,y)→(y,−x)
B. (x,y)→(y,x)
C. (x,y)→(−y,x)
D. (x,y)→(−y,−x)
Answer:
A. [tex](x,y)\rightarrow (y,-x)[/tex]
Step-by-step explanation:
We have been given that figure ABCD is a rectangle with point A (−2, 5). We are asked to choose the rule that would rotate the figure 90° clockwise.
We know that rule of rotating a figure 90 degrees clockwise is: [tex](x,y)\rightarrow (y,-x)[/tex]
Upon looking at our given choices we can see that option A is the correct choice.
After rotating our given point 90 degree clockwise, the coordinates of point A would be:
[tex](-2,5)\rightarrow (5,--2)=(5,2)[/tex]
What is the solution to this system of linear equations?
x + y = 4
x − y = 6
Answer:
x = 5 and y = -1
Step-by-step explanation:
[tex]x + y = 4[/tex]
[tex]x - y = 6[/tex]
To solve for x and y , we use elimination method
In the given equations, the co efficient of y are same with different coefficient
So we add both equations
[tex]x + y = 4[/tex]
[tex]x - y = 6[/tex]
--------------------------------
[tex]2x=10[/tex]
Divide both sides by 2
x= 5
now we plug in x value in first equation
[tex]5 + y = 4[/tex]
Subtract 5 on both sides
y= -1

The survey of study habits and attitudes (ssha) is a psychological test that measures the motivation, attitude, and study habits of college students. scores range from 0 to 200 and follow (approximately) a normal distribution with mean 115 and standard deviation 25. you suspect that incoming freshmen at your school have a mean μ which is different from 115 because they are often excited yet anxious about entering college. to test your suspicion, you decide to test the hypotheses h0: μ = 115 versus ha: μ ≠ 115. you give the ssha to 25 incoming freshmen and find their mean score to be 116.2. what is the value of the test statistic?
Final answer:
The value of the test statistic in this scenario is 0.24, calculated using the z-score formula based on the provided sample mean, population mean, standard deviation, and sample size.
Explanation:
The value of the test statistic for a hypothesis testing can be calculated using the formula for the z-score, which is (sample mean - population mean) / (standard deviation / √sample size). In this case, given that the sample mean is 116.2, the population mean is 115, the standard deviation is 25, and the sample size is 25 students, the test statistic can be calculated as follows:
(116.2 - 115) / (25 / √25)
This computation yields a z-score of:
(1.2) / (25 / 5)
(1.2) / 5 = 0.24.
Therefore, the value of the test statistic is 0.24.
Which method of reasoning reaches a general conclusion on the basis of a number of observations that form a pattern?
deductive reasoning
inductive reasoning
complementary reasoning
supplementary reasoning
Answer:
Deductive reasoningStep-by-step explanation:
Deductive reasoning can be defined as the process of reasoning based on premises to reach a specific conclusion.
So, in this case, the statement indicate a method of reasoning based on a number of observations that can lead to a conclusion. That's just deductive reasoning, because those number of observations form the system of premises, from which a deductive logic is developed to get to the conclusion.
Therefore, the right answer is the first choicem, deductive reasoning.

The perimeter of a rectangular slab of concrete is 24 meters. If the length of the
rectangular slab is 2 meters longer than its width, what is the width of the slab?
Answers:
A) 5 meters
B) 6 meters
C) 7 meters
D) 8 meters
The answer is 5 meters but i don't know how to get that. HELP
The width of the slab is 5 meters which is correct option(A).
What is perimeter of rectangle?Perimeter of rectangle is defined as addition the lengths of the rectangle's four sides.
Let length of slab is L, width is W,
The perimeter of a rectangular slab = 24
2(length) + 2(width) = 2L + 2W = 24
If the length of the rectangular slab is 2 meters longer than its width
= width + 2
So, the equation L = W+2
Now substitute, L= W+2 in equatioin of perimeter,
2(W+2) + 2W = 24
2W + 4 + 2W = 24
4W = 24-4 = 20
W = 20/4 = 5
W = 5
Hence, the width of the slab is 5 meters.

A person is standing exactly 36 ft from a telephone pole. There is a 30 degree angle of elevation from the ground to the top of the pole. What is the height of the pole?
By using the tangent function in trigonometry, we find that the height of the telephone pole is approximately 20.78 feet. This was calculated using the given angle of elevation and the distance from the pole.
To find the height of the telephone pole, we can use trigonometry, specifically the tangent function. The tangent of an angle in a right triangle is the ratio of the opposite side to the adjacent side.
Given:
Distance from the person to the base of the pole (adjacent side) = 36 ftAngle of elevation from the ground to the top of the pole = 30 degreesWe know that:
tan(30°) = opposite / adjacent
So,
tan(30°) = height / 36 ft
From a trigonometric table or calculator, tan(30°) ≈ 0.5774.
We can set up the equation as:
0.5774 = height / 36 ft
Solving for the height of the pole:
height = 0.5774 * 36 ftheight ≈ 20.78 ftTherefore, the height of the pole is approximately 20.78 feet.

E to F is 6 F to G is x
and overall distance from e to g is 1.6x
so:
6+x = 1.6x
subtract x from each side
6 = 0.6x
now divide both sides by .6
x = 6/0.6 = 10
x = 10

If two tangent segments to a circle share a common endpoint outside a circle, then the two segments are
If two tangent segments to a circle share a common endpoint outside a circle, then the two segments are congruent. This is according to the intersection of two tangent theorem. The theorem states that given a circle, if X is any point within outside the circle and if Y and Z are points such that XY and XZ are tangents to the circle, then XY is equal to XZ.
Final answer:
Two tangent segments to a circle that share a common endpoint outside the circle are congruent, meaning they have the same length. This is a fundamental concept in circle geometry, illustrating the unique properties of tangents and their interactions with circles.
Explanation:
If two tangent segments to a circle share a common endpoint outside a circle, then the two segments are congruent. This means the lengths of the two tangent segments from the common external point to their respective points of tangency on the circle are equal. This concept is important in the study of circle geometry, as it helps in understanding relationships between tangents and circles.
A tangent to a circle is a line that touches the circle at exactly one point, ensuring it does not cross the circle at that touchpoint. This property of tangents being congruent when they share an external point is proven using the properties of right triangles and the fact that tangents from a point outside the circle to the circle are perpendicular to the radius at the point of tangency.
An example of this concept in action is if you draw two tangents from a single point outside of the circle to any two points on the circle's boundary, the segments of these tangents from the external point to the points of tangency will have the same length.
