Question 2 Part B (5 points): Given the area of the square, find the length of each side by factoring completely. Be sure to show all work to receive full credit!
Area: 25y² – 20y + 4 sq units
formula : area of square = Length²
all the sides in a square is of same measureLength = √area of square
given here the area: 25y² – 20y + 4[tex]\rightarrow \sf Length =\sqrt{ 25y^2 - 20y + 4}[/tex]
[tex]\rightarrow \sf Length =\sqrt{ 25y^2 - 10y -10y+ 4}[/tex]
[tex]\rightarrow \sf Length =\sqrt{ 5y(5y - 2) -2(5y-2)}[/tex]
[tex]\rightarrow \sf Length =\sqrt{ (5y-2)(5y-2)}[/tex]
[tex]\rightarrow \sf Length =\sqrt{ (5y-2)^2}[/tex]
[tex]\rightarrow \sf Length =5y-2[/tex]

B IS INCORRECT
Answer:
Choice D
Step-by-step explanation:
Multiply the scalar into the matrix
3*2
3*-1
The first matrix becomes
6
-3
6 - 0
-3 =1.5
We are subtracting a negative so it is like adding
6 + 0
-3 + 1.5
6
-1.5
Choice D
Answer:
4th option
Step-by-step explanation:
3 [tex]\left[\begin{array}{ccc}2\\-1\\\end{array}\right][/tex] - [tex]\left[\begin{array}{ccc}0\\-1.5\\\end{array}\right][/tex] ← multiply the components of the first matrix by 3
= [tex]\left[\begin{array}{ccc}6\\-3\\\end{array}\right][/tex] - [tex]\left[\begin{array}{ccc}0\\-1.5\\\end{array}\right][/tex] ← subtract corresponding components
= [tex]\left[\begin{array}{ccc}6-0\\-3-(-1.5)\\\end{array}\right][/tex]
= [tex]\left[\begin{array}{ccc}6\\-3+1.5\\\end{array}\right][/tex]
= [tex]\left[\begin{array}{ccc}6\\-1.5\\\end{array}\right][/tex]

sin∅ = opposite over hypotenuse
Since we have a right triangle, we can use trig to help us solve for missing values:
sin30° = 4/x
xsin30° = 4
x = 4/sin30°
x = 8

Find the percent change. State whether it is an increase or decrease. Round to the nearest tenth of a percent. From 27 to 31
Given parameters:
Initial value = 27
Final value = 31
Unknown:
Percentage change = ?
Solution:
The percentage change is the difference between the final and initial value divide by the initial value multiplied by 100;
Percentage change = [tex]\frac{Final value - Initial value}{Initial value} x 100[/tex]
Input the parameters and solve;
Percentage change = [tex]\frac{31 - 27}{27} x 100[/tex]
= 14.8%
The percentage change is 14.8%. This is an increase because the value move from 27 to 31.

Use vector operations to draw the resultant vector
Draw 2u – 1/3v.
Vectors are elements of the vector space, and they can be illustrated by diagrams.
How to draw the vector 2u - 1/3vThe vector expression is given as:
2u - 1/3 v
Split the vector expressions, as follows:
[tex]y_1 = 2u[/tex]
[tex]y_2 = -\frac13v[/tex]
See attachment for the graphs of y1 and y2.
Next, we have:
[tex]y = 2u - \frac13v[/tex]
So, we have:
[tex]y = y_1 + y_2[/tex]
The above expression means that, we add the vectors y1 and y2 to get vector y

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y > 3x + 10
y is less than negative 3 over 4 times x minus 1
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically

Answer:
A) The graph is the quadrant of the coordinate plane that lies between the two lines and to the left of the point (-2 14/15, 1 1/5)
B) no; it does not satisfy either inequality
Step-by-step explanation:
A) The boundary line defined by the first inequality is a dashed line with a slope of 3 and a y-intercept of 10. Shading is above the line (and to its left).
The boundary line defined by the second inequality is a dashed line with a slope of -3/4 and a y-intercept of -1. Shading is below the line (and to its left).
The two lines cross at the 2nd-quadrant point (-2 14/15, 1 1/5). The solution area is the area between the crossing lines and to the left of that point. Neither that point nor any point on either line is part of the solution area.
The solution area is the doubly-shaded area in the attached graph.
__
B) The first-quadrant point (8, 10) is not in the solution area, since the solution area is comprised of parts of quadrants 2 and 3 only.
We can see that (8, 10) will not satisfy either inequality:
10 > 3(8) +10 . . . . not true
10 < -3/4(8) -1 . . . . not true
find the area pls i need it
Answer:
521 mm²
Step-by-step explanation:
Hi there !
A = Asemicircle + Atrapeze
Asemicercle formular = d/2 = 20mm/2 = 10mm
Asc = π·r²/2
= 3.14·(10mm)²/2
= 3.14×100mm²/2
= 157 mm²
Atrapeze formulaAt = (b + B)×h/2
= (20mm + 32mm)×14mm/2
= 52mm×7mm
= 364 mm²
A = Asc + At= 157mm² + 364mm²
= 521 mm²
Good luck !
Can you help me find the surface area of this prism?
Answer:
To find the surface area of this parallelepiped, we need to know how to find the area of a regular parallelogram.
Formula for area of a parallelogram;
A = BH
Where b represents the base, and h displays as the height.
Once, we know how to find the area of a parallelogram, we find the areas of the three different sides of this figure and multiply it by two since opposite sides have an equal area.
Now we find the area of the front parallelogram:
A = BH
Plug in our values;
A = 4(2)
A = 8, and since opposite sides are equal:-
8(2) = 16, is the area of both the front and back parallelograms.
Now the top and bottom bases of this parallelepiped.
But, to find the height and base of this, we transfer the base of the front parallelogram and the base of the right parallelogram. So our base and height is 4.
A = BH
Plug in our values;
A = 4(4)
A = 16, and since opposite sides are equal:-
16(2) = 256, is the area for both the upper and bottom bases.
Now for the right and left parallelograms;
A = BH
Plug in our values;
A = 4(2.5)
A = 10, since opposite sides are equal:-
10(2) = 20, is the area of both the right and left parallelograms.
Now we add all the areas together:
16 + 256 + 20
= 292 square meters.
subtract 7/10 - 1/5 simplify your answer
Answer:
1/2
Step-by-step explanation:
7/10 - 1/5
=> 7/10 - 1*2/5*2
=> 7/10 - 2/10
=> (7-2)/10
=> 5/10
=> 1/2
first, you have to make sure they have the same bottom number so you would make 1/5 2/10.
7/10-2/10
which is 5/10
you would simplify it and get 1/2 because 5 is half of 10

Based on the table, what is the number string that corresponds to the text “Hello Raya”?
The number string is an illustration of the addition operation
The number string that corresponds to the text “Hello Raya” is 97
How to determine the number string?The text is given as:
“Hello Raya”
From the table in the complete question, we have the following representations:
H = 8; E = 5; L = 12; O = 15; R = 18; A = 1; Y = 25; _ or space = 0
The sum of the numerical values of the characters are:
Sum = 8 + 5+ 12 + 12 + 15 +0 + 18 + 1+ 25 + 1
Evaluate the sum
Sum = 97
Hence, the number string that corresponds to the text “Hello Raya” is 97
