Quadrilateral MNOP is a rhombus. Find the measure of angle MRN.
a. 90
b. 45
c. 85
d. 60
Without further information or a diagram indicating the position of point R in the rhombus MNOP, we cannot accurately determine the measure of angle MRN. If R is at the intersection of the diagonals, angle MRN would be 90 degrees.
Explanation:The student asks to find the measure of angle MRN in a rhombus named MNOP. Unfortunately, the information provided is insufficient to determine the measure of angle MRN directly. However, one property of a rhombus is that all sides are of equal length and opposite angles are equal. Additionally, the diagonals of a rhombus are perpendicular bisectors of each other and bisect the angles of the rhombus. Without a specific diagram or more information about the location of point R in relation to the rhombus, it's impossible to give an exact answer. If R is located at the center where the diagonals intersect, then angle MRN would be 90 degrees because the diagonals of a rhombus bisect each other at right angles. If R is not at the center, then we cannot determine the angle without additional information.
Which is a secant of circle A?
(Points : 1)
segment AB
line DE
segment HG
line CD
Answer:
The correct option is line CD
Step-by-step explanation:
Given the diagram we have to find the secant of circle A.
Secant of a circle is a line intersecting the circle at exactly two different points and a chord is the line determined by these two.
In the circle A the only line intersect two different points is CD and the interval on a secant is the chord of circle.
Here, HG is only the chord of circle not secant.
Hence, the correct option is line CD
How would i find the rule for this pattern:1280,640,320,160?
The rule for this pattern is to divide each number by 2 to get the next number.
Explanation:To find the rule for this pattern, we need to identify the relationship between the numbers. In this case, each number is half of the previous number. So, to find the next number, we divide the previous number by 2.
For example, 640 is half of 1280, 320 is half of 640, and so on. This means that to find the next number, we divide 320 by 2 to get 160.
Therefore, the rule for this pattern is to divide each number by 2 to get the next number.

Which of the following correctly expresses the number below in scientific notation? 0.00000765
A. 7.65 • 10-6
B. 7.65 • 10-7
C. 7.65 • 10-5
D. 76.5 • 10-7
E. 765 • 10-8
F. 765 • 10-6
In scientific notation, 0.00000765 is written as 7.65 • 10-6. This represents the number of places to the right of the decimal point to the first non-zero digit.
Explanation:The task is to express the number 0.00000765 in scientific notation. Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in standard decimal form. It is commonly used in science and mathematics.
We have to determine which of the given options correctly represents this number in scientific notation.
The number 0.00000765 can be written as 7.65 times ten to the negative sixth power. This is because there are six places to the right of the decimal point before we encounter the first non-zero digit. Therefore, the correct answer is 7.65 • 10-6.

6.25 in Answer:
6.25 in
Step-by-step explanation:
i took the text
Final answer:
The length of the enlarged photo is 6.25 inches.
Explanation:
The question asks for the length of an enlarged photo when its width, the shorter dimension, has been increased from 4 inches to 5 inches. This is a problem of similar rectangles where the aspect ratio must remain constant. In the original photo, the width is 4 inches and the length is 5 inches. As the photo is enlarged, and the new width becomes 5 inches, we must find the new length that keeps the aspect ratio the same.
To find the scale factor, you compare the new width to the original width:
Scale factor = new width / original width = 5 inches / 4 inches = 1.25
To find the new length, multiply the original length by the scale factor:
New length = original length × scale factor = 5 inches × 1.25 = 6.25 inches
Therefore, the length of the enlarged photo is 6.25 inches.

If P(x) = 2x 4 - x 2 + 3x - 1, use synthetic division to find P (2).
17
21
33
Answer: 33
Step-by-step explanation:
P(x) = 2x 4 - x 2 + 3x - 1
To find the value of p(2) we simply substitute x = 2.
That is; wherever you see x, simply put 2
P(2) = 2 [tex](2)^{4}[/tex] - [tex](2)^{2}[/tex] + 3(2) - 1
=2(16) - 4 + 6 - 1
= 32 - 4 + 6 -1
=28 + 6 -1
=34 - 1
=33
Therefore the value of P(2) is 33

"In ABC, mBAC = 5x + 8, mABC = 6x + 22, and mBCA = 3x 25.
A.Find the value of x.
B.Find the measure of 3. Show your work."
Actually, the answer is 12.5
5x+8+6x+22+3x+25= 180
(5x+6x+3x)+(8+22-25)= 180
14x+5=180
14x+(5-5)=180-5
14x=175
14x/14=175/14
X=12.5
Double check:
(5*12.5)+8=70.5
(6*12.5)+22= 97
(3*12.5)-25=12.5
70.5+97+12.5=180 degrees.
So, x=12.5

1. What is the sum of the polynomials?
(m + n + 3) + (m + n + 4)
2. Find the difference of the polynomials
(10m – 6) – (7m – 4)
3. Find the difference of the polynomials
(4m – 5) – (6m – 7 + 2n)
Answer:
1. 2m+2n+7
2. 3m-2
3.-2m+2-2n
Explanation:
To find the sum of given polynomials (m+n+3) +(m+n+4)
Firstly, open the parenthesis we will get m+n+3+m+n+4
After simplification we will get 2m+2n+7
To find the difference of given polynomials (10m-6)-(7m-4)
Firstly, open the parenthesis we will get 10m-6-7m+4
After simplification we will get 3m-2
Again to find the difference of the polynomials (4m-5)-(6m-7+2n)
Firstly, open the parenthesis we will get 4m-5-6m+7-2n
After simplification we will get -2m+2-2n
The sum of the polynomials (m + n + 3) and (m + n + 4) is 2m + 2n + 7. The difference of the polynomials (10m – 6) and (7m – 4) is 3m - 2. The difference of the polynomials (4m – 5) and (6m – 7 + 2n) is -2m - 2n - 2.
Explanation:To find the sum of the polynomials (m + n + 3) and (m + n + 4), we simply combine like terms:
(m + n + 3) + (m + n + 4)
= m + m + n + n + 3 + 4
= 2m + 2n + 7.
To find the difference of the polynomials (10m – 6) and (7m – 4), we subtract the second polynomial from the first:
(10m – 6) – (7m – 4)
= 10m - 7m - 6 + 4
= 3m - 2.
Lastly, to find the difference of the polynomials (4m – 5) and (6m – 7 + 2n), we again subtract the second polynomial from the first:
(4m – 5) – (6m – 7 + 2n)
= 4m - 6m + 5 - 7 - 2n
= -2m - 2n - 2.

Which of the points shown below are on the line given by the equation y = x - 1? Check all that apply.
A. Point A: (1, -2)
B. Point B: (2, 1)
C. Point C: (4, 3)
D. Point D: (-3, -4)
Final answer:
To find points on the line y = x - 1, substitute the x and y values of each point into the equation. Points B, C, and D satisfy the equation.
Explanation:
The equation given is y = x - 1. To determine which points lie on this line, you need to substitute the x and y values of each point into the equation and see if the equation holds true.
Point A: (1, -2) - Substitute x = 1, y = -2 into y = x - 1. -2 = 1 - 1 is false.Point B: (2, 1) - Substitute x = 2, y = 1 into y = x - 1. 1 = 2 - 1 is true.Point C: (4, 3) - Substitute x = 4, y = 3 into y = x - 1. 3 = 4 - 1 is true.Point D: (-3, -4) - Substitute x = -3, y = -4 into y = x - 1. -4 = -3 - 1 is true.Therefore, Points B, C, and D lie on the line represented by the equation y = x - 1.
