The rule T1, -4 RO, 180°(x, y) is applied to rectangle KLMN. Which rectangle shows the final image??
Answer:
Figure 3.
Step-by-step explanation:
We perform the rotation first. A 180° rotation about the origin maps every point
(x, y)→(-x, -y). This means it negates both the x- and y-coordinates.
The pre-image points are:
K(3, -4); L(3, -1); M(5, -1); N(5, -4). Performing the rotation and negating the coordinates will give us:
K'(-3, 4); L'(-3, 1); M'(-5, 1); N'(-5, 4).
Now we perform the translation. The translation rule is <1, -4>; this means we add 1 to each x-coordinate and subtract 4 from each y-coordinate. This maps to our new points:
K''(-2, 0); L''(-2, -3); M''(-4, -3); N''(-4, 0)
These are the points of figure 3.

Which transformations can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4)? a 180 (dagree) rotation about the origin a 90 (dagree) counterclockwise rotation about the origin and a translation down 4 units a 90 (dagree) clockwise rotation about the origin and a reflection over the y-axis a reflection over the y-axis and then a 90(dagree) clockwise rotation about the origin
The triangle ABC is mapped to A'B'C' through a 180-degree rotation about the origin, as all the points' x and y coordinates have changed signs, consistent with this transformation.
To determine which transformations can map the original triangle ABC to the new triangle A'B'C', we must closely examine the coordinates given and analyze the possible transformations.
Looking at the coordinates:
A(2, 2) to A'(-2, -2) suggests a reflection over the origin, which can be considered as a 180-degree rotation around the origin.
B(4, 1) to B'(-1, -4) also suggests a similar transformation, as the x and y values are negated and swapped in position.
C(4, 5) to C'(-5, -4) follows the same pattern.
All these transformations indicate that the original triangle has been rotated 180 degrees about the origin. This can also be observed by noting that the x and y coordinates have simply changed their signs, an effect of 180-degree rotation about the origin. This satisfies the claim of the classical geometry theorem which states that such transformations can be expressed as either a translation or a rotation. In this case, it's purely a rotation as there's no translation component.

Find the surface area of a pyramid with a square base with dimensions 100 mm by 100 mm and height of 75 mm.
To solve for the surface area of the pyramid, we make use of the formula:
A= l w + l [sqrt ((w / 2)^2 + h^2)] + w [sqrt ((l / 2)^2 + h^2))
where,
l and w are the base of the pyramid = 100 mm
h is the height of the pyramid = 75 mm
Substituting the given values into the equation:
A= 100 * 100 + 100 [sqrt ((100 / 2)^2 + 75^2)] + 100 [sqrt ((100 / 2)^2 + 75^2))
A = 10,000 + 100 (sqrt 2575) + 100 (sqrt 2575)
A = 20,148.90 mm^2
Therefore the surface area of the pyramid is about 20,149 mm^2.

Read the following statement: All real numbers have a reciprocal. Which of the following choices is a counterexample to the statement?
1/4
0
1
-7
Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
All real numbers have a reciprocal.
But we know that 0 has no inverse, means there is no reciprocal exists for 0.
Because,
[tex]\dfrac{1}{0}=\infty[/tex]
So, 0 is a counter example to the statement.
Hence, Second option is correct.

A rectangular box has dimensions of length = 6, width = 4, and height = 5. the measure of the angle formed by a diagonal of the box with the base of the box is
To find the angle formed by a diagonal of a rectangular box with its base, calculate the base diagonal using the Pythagorean Theorem and then use the inverse tangent function with the height and base diagonal as arguments.
Explanation:The angle formed by a diagonal of the rectangular box with the base of the box can be found using the Pythagorean Theorem. In this case, the box has a length of 6, a width of 4, and a height of 5. The diagonal of the base can be calculated as the hypotenuse of a right triangle formed by the length and the width. According to the Pythagorean theorem, this diagonal (D) is √(6² + 4²) which is √(36 + 16) or √52. To find the angle between the box's base diagonal and the body diagonal (which includes the height), we need to use trigonometry, specifically the inverse tangent function (tan-1). So we have the length of the box's base diagonal (D) and the height (H), forming a right triangle with the body diagonal as the hypotenuse. The angle θ can be calculated using tan-1(H/D), where H is the height of the box and D is the length of the diagonal on the base. This equates to tan-1(5/√52). Evaluating this expression with a calculator gives us the angle θ formed by the body diagonal with the base of the box.

How long does it take a plane, traveling at a speed of 110 m/s, to fly once around a circle whose radius is 2850 m?
Answer:
It takes to the plane [tex]162.792[/tex] seconds to fly once around a circle whose radius is 2850 m at a speed of [tex](110)\frac{m}{s}[/tex]
Step-by-step explanation:
The first step in this exercise is to find the total distance that the plane will fly.
This distance is equal to the perimeter of a circle whose radius is 2850 m.
Given a circle of radius R, the perimeter ''P'' can be calculated as :
[tex]P=\pi .d=\pi .2.R[/tex]
Where ''d'' is the diameter of the circle that is equal to 2.R
The distance that the plane will fly in the exercise is :
[tex]P=\pi .2.R=\pi .2.(2850m)=17907.078m[/tex]
Now, the speed is equal to distance divided by time.
[tex]speed=\frac{distance}{time}[/tex]
We have the speed of the plane and the distance (that is the perimeter ''P'' of the circle). We only need to replace this values in the equation and find the time variable.
[tex](110)\frac{m}{s}=\frac{(17907.078)m}{t}[/tex]
[tex]t=\frac{(17907.078)m}{(110)\frac{m}{s}}=(162.792)s[/tex]
[tex]t=(162.792)s[/tex]
We find that the time is [tex]162.792[/tex] seconds.

A committee of 3 people is to be randomly selected from a group of 5 women and 8 men. What is the probability that the committee will consist only of women?
A.
5/143
B.
7/143
C.
28/143
D.
30/143
Answer:
[tex]A. \frac{5}{143}[/tex]
Step-by-step explanation:
Given,
Number of women = 5,
Number of men = 8,
Total persons = 5 + 8 = 13,
∵ Ways of selecting any 3 persons = [tex]^{13}C_3[/tex]
Also, the ways of selecting 3 women = [tex]^5C_3[/tex]
Hence, the probability of selecting 3 women
[tex]=\frac{\text{Ways of selecting any 3 women}}{\text{ Ways of selecting any 3 persons}}[/tex]
[tex]=\frac{^5C_3}{^{13}C_3}[/tex]
[tex]=\frac{\frac{5!}{2!3!}}{\frac{13!}{3!10!}}[/tex]
[tex]=\frac{10}{\frac{13\times 12\times 11}{6}}[/tex]
[tex]=\frac{60}{13\times 12\times 11}[/tex]
[tex]=\frac{5}{143}[/tex]
Hence, OPTION A is correct.
Quadrilateral abcd has side lengths of ab = 13w 5, bc = 5z 2, cd = 13w 5, and ad = 3z + 5. find the value of z for which quadrilateral abcd is a parallelogram.
To find 'z', utilise the properties of a parallelogram where opposite sides are equal. Setting these sides equal to each other and solving for 'z' provides the answer, 'z' = 3.5.
Explanation:In this problem, you're given a quadrilateral ABCD for which you are supposed to find the value of 'z' when the quadrilateral is a parallelogram. In a parallelogram, the opposite sides are equal. Therefore, we can set AB = CD and BC = AD, and then solve for 'z'. From AB = CD (13w + 5 = 13w + 5), no information is required as their lengths are already equal. From BC = AD (5z - 2 = 3z + 5), solving for 'z' would give us 'z' = 7/2 or 3.5.

The numbers 2/3 5/6 and 9/4
Now,
To find the least common multiple of fractions, we need to find the least common multiple of their denominators and divide it by the greatest common factor of their numerators. The steps are:
Multiples of 3: 3, 6, 9, 12, 15, 18,
Multiples of 6: 6, 12, 18,
Multiples of 4: 4, 8, 12,
Find the greatest common factor of 2, 5 and 9. This is the largest number that can divide all three numbers without leaving a remainder. One way to do this is to list the factors of each number and find the largest one that they have in common. For example:
Factors of 2: 1 and 2
Factors of 5: 1 and 5
Factors of 9: 1,3 and9
The only common factor is 1, so this is the greatest common factor of the numerators.
