Suppose you have two 3 by 3 matrices ,say A and B How can the square of the A and B be mathematically expressed a).AB² b).[AB]² Which one the two is correct?
Answer:
[tex][AB]^2[/tex]
Step-by-step explanation:
Given
Matrices A and B
Required
Represents the square of A and B
The interpretation of the question is that:
The square of the product of A and B
This can be represented as:
The square(product of A and B)
Product means *
So, we have:
The square(A * B)
The square means ^2
So, we have:
[tex][A * B]^2[/tex]
This gives:
[tex][AB]^2[/tex]
Hence, the second option is correct

An electronics store buys 200 stylus at a cost of $400 and sells them for $6 each. Find the percent markup rounded to the nearest percent?
Answer:
Percent markup is 200%
Step-by-step explanation:
The cost of each stylus is
[tex]\frac{400}{200} = 2[/tex] dollars
The selling price of each stylus is $6
Percent markup =
(Selling price - cost price)/cost price *100
[tex]\frac{6-2}{2} *100\\2*100\\200[/tex]%
Percent markup is 200%

What is the value of this expression when c=-4 and d = 10?
1/4(c3+d2)
What is the value of this expression when c = -4 and d = 10 ? [tex] \frac{1}{4} [/tex] (c³ + d²)
Answer:-Given:-[tex] \frac{1}{4} [/tex] (c³ + d²) where c = -4 and d = 10
To Find:-The value of the expression [tex] \frac{1}{4} [/tex] (c³ + d²)
Solution:-[tex] \frac{1}{4} [/tex] (c³ + d²) [Given expression]
Now, putting the value of c = -4 and d = 10 , we get,
[tex] \frac{1}{4} [/tex] { (-4)³ + (10)² }
[tex] \frac{1}{4} [/tex] ( -64 + 100 )
[tex] \frac{1}{4} [/tex] ( 36 )

What is the measure of angle 4?
angles 1,3,5,6,7, and 8 are 73 degrees. angles 2 is 107 degrees
Answer:
34 Deg
Step-by-step explanation:
Since the Triangle is isoceles, each of the internal base angle = 180-107=73
Sum of internal angles =180, Angle4= 180-(73+73)= 180-146=34
3. Sue's average for 9 games of bowling is 108. What is the lowest score she can receive for the
tenth game to have an average of 110?
Answer: 128
Step-by-step explanation:
Sue's average for 9 games of bowling is 108. Therefore, the total scores for the 9 games is:
= 108 × 9
= 972
To have an average of 110 in 10 games, her total score will be:
= 110 × 10
= 1100
Therefore, the lowest score that she can get will be the difference between the values calculated above and this will be:
= 1100 - 972
= 128
What are the coordinates of Rx=3(G)?
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms
r = [tex]\frac{384}{512}[/tex] = [tex]\frac{288}{384}[/tex] = [tex]\frac{216}{288}[/tex] = [tex]\frac{3}{4}[/tex] , then recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex] : a₁ = 512

if the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.
A. 13.17
B. 12.25
C. 11.32
D. 10.42
Answer:
m = rise/run = 270/20.5 = 13.17
Step-by-step explanation:
Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270. Thus, the slope is
m = rise/run = 270/20.5 = 13.17
Line x and line z are straight lines.
Which pair of angles are vertical?
O Za and Zd
Zb and Zd
Za and ZD
O Zc and Ze
Mark this and return
Answer:
[tex]\angle c[/tex] and [tex]\angle e[/tex]
Step-by-step explanation:
Given
See attachment
Required
Identify the vertical angles
Keynotes
Vertical angles opposite one anotherVertical angles are equal to one anotherUsing the keynote as a reference, we have the following observation from the attachment:
[tex]\angle c[/tex] and [tex]\angle e[/tex] are opposite
[tex]\angle c[/tex] and [tex]\angle e[/tex] are congruent
Hence:
[tex]\angle c[/tex] and [tex]\angle e[/tex] are vertical
(d) is correct
What value of y makes the equation 4x – 3y = 17 true, when x = 2?
Answer:
y = -3
Step-by-step explanation:
4x – 3y = 17
x = 2
4(2) - 3y = 17
8 - 3y = 17
-3y = 9
y = -3
Answer:
y= -3
Step-by-step explanation:
if x =2, substitute
4(2) - 3y = 17
8-3y = 17
(add 3y to both sides)
8= 17 + 3y
(subtract 17 from both sides)
8-17=3y
-9= 3y
(divide both sides by 3)
-9/3=y
y= -3

Find the volume of a right circular cone that has a height of 2.4 in and a base with a
radius of 10.6 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
282.4
Step-by-step explanation:
V=1/3 pi Bh where B is the area of the base and h is the height
V=1/3 (3.14159)(10.6)^2(2.4)=282.4
Answer:
282.4 in^3
Step-by-step explanation:π
The volume of a cone is represented by the equation [tex]v=\frac{1}{3\\}\pi r^2*h[/tex] where r is the radius of the base and h is the height. Substituting in our values for the radius and height we get:
v=1/3π*10.6^2*2.4
v=1/3*2.4*112.36*π
v=0.8*112.36*π
v=89.888*3.14
v=282.4 in^3
