Trapezoid K prime is the image of trapezoid K after a series of transformations.
On a coordinate plane, trapezoid K has points (negative 4, 0), (negative 4, 4), (4, 4), (2, 0). Trapezoid K prime has points (negative 3, negative 1), (6, negative 1), (6, negative 7), (negative 6, negative 7).
Bella and Marco described the sequence of transformations in different ways.
Bella’s Sequence
Marco’s Sequence
1. a dilation of trapezoid K by a scale factor of Three-halves with the origin as the center of dilation
2. a rotation of 180 degrees about the origin
3. a translation of 1 unit down
1. a reflection of trapezoid K across the x-axis
2. a dilation by a scale factor of Three-halves with the origin as the center of dilation
3. a translation of 1 unit down
Which sequence or sequences are correct and why?
Only Bella is correct.
Only Marco is correct.
Both Bella and Marco are correct because both chose the correct scale factor for the dilation and both describe other transformations that could be used.
Neither Bella nor Marco is correct because the scale factor they chose for the dilation is incorrect.

The length, in millimeters of each side of a square shaped electronic chip is a rational number. What statement is true about the length of the diagonal of the chip
Answers
Answer:
The diagonal is irrational because it is a product of a rational and an irrational number
Step-by-step explanation:
The options are not given. However, the question is still answerable.
Given
Shape: Square
Length: Rational
Since the side length is said to be rational, I'll answer the question based on whether the diagonal is rational or not.
Having said that:
The diagonal (d) of a square with side length (l) is calculated using Pythagoras theorem.
[tex]d^2 = l^2 + l^2[/tex]
[tex]d^2 = 2l^2[/tex]
Take positive square root of both sides
[tex]d = \sqrt{2l^2}[/tex]
Split:
[tex]d = \sqrt{2} * \sqrt{l^2}[/tex]
[tex]d = \sqrt{2} *l[/tex]
Recall that the side length (l) is rational.
However, [tex]\sqrt 2[/tex] is irrational.
So, the product of l and [tex]\sqrt 2[/tex] will be irrational
Hence:
The diagonal is irrational

A given set of data is said to have a greater spread if it covers a large scale/area. Since the data set 3 only covers a small portion of a wide spectrum it is said to have a smaller spread when in comparison with data set 4 which has a greater spread as it covers a larger scale/spectrum.
▪︎Therefore, Data set 4 has a greater spread.
○=> Solution (8) :Lower quartile of a data set is said to be the median of the lower half of the data set.
Lower quartile of this data set :
[tex] = \tt \frac{50 + 60}{2} [/tex]
[tex] =\tt \frac{110}{2} [/tex]
[tex]\color{plum} =\tt 55[/tex]
Thus, the lower quartile of this data set = 55
Median is said to be the middle element of a data set.
The median of this data set = 80
Upper quartile of a data set is said to be the median of the upper half of a given data set.
Upper quartile of this data set :
[tex] =\tt \frac{110 + 100}{2} [/tex]
[tex] =\tt \frac{210}{2} [/tex]
[tex]\color{plum} = \tt105[/tex]
Thus, the upper quartile of this data set = 105
Therefore :▪︎Lower quartile of this data set = 55
▪︎Upper quartile of this data set = 105
▪︎Median of this data set = 80

A carpenter has several boards of equal length. He cuts 3/5 of each broads.After cutting the boards the carpenter notices that he has enough pieces left over to make up the same length as 4 of the original board. How many boards did the carpenter star with?
Answers
Answer:
10
Step-by-step explanation:
Length of boards are the same :
Let number of boards = x
Fraction cut from each board = 3/5
Total fraction cut = 3/5 * x
Fraction left = 1 - 3/5 = 2/5
Total fraction left = 2/5 * x
Total pieces left = 2/5 * x = 4 times length of original board
Note ; original fraction = 1
Hence,
2/5 * x = 4 * 1
2x / 5 = 4
2x = 4 * 5
2x = 20
x = 20 / 2
x = 10
Number of boards = 10

One of the roots of equation x^(2)-(3p-4)x+11p-5=0 is 8. Find the other root. Find the value of p.
Answers
Answer:
Other root is 9 and p = 7.
Step-by-step explanation:
x^(2) - (3p-4)x + 11p-5 = 0 , x = 8.
Let the other root be A, then using the formula for the product and sum of the roots of a quadratic equation:
8* A = 11p - 5
8 + A = -(-(3p - 4))
8 + A = -(-3p + 4)
8 + A = 3p - 4
A = 3p - 12.
Multiply this last equation by 8:
8A = 24p - 96
Now subtract the first equation from this:
8A - 8A = 24p - 11p - 96- (-5)
0 = 13p - 91
13p - 91 = 0
p = 91/13 = 7
and A = 3(7) - 12
= 9.
Answer:
Other root 9, p is 7

Answer:
The answer is 1/625
Step-by-step explanation:
The reason is because 5a = 1/125
Therefore, to find the value of "a" we need to divide!
So, a = 1/125 / 5
⇒ 1/125 × 1/5 ( Reciprocal when we divide )
⇒ 1/125 × 5
→ 1/625
