Suppose matrix D is the inverse of matrix C. Which of the following is equal to D?
O CDD
O CCD
O DDD
O CCC
==========================================
Explanation:
C and D are inverses of each other. When they multiply together, they will produce the identity matrix I
C*D = I
D*C = I
note: this is the uppercase letter 'i' and not the number one. The 'i' stands for 'identity'. Another thing to note is that matrix multiplication is not normally commutative, but it works for matrix inverses.
--------------------
So this means C*D*D = (C*D)*D = (I)*D = I*D = D because multiplying the identity matrix with some matrix X leads to the same matrix X.
This is why the first choice is the answer.
The second choice doesn't work because C*C*D = C*(C*D) = C*(I) = C*I = C
The third choice doesn't work because we don't have any C's here. All we can say is that D*D*D = D^3
Similarly choice 4 doesn't work as all we can say is C*C*C = C^3.

The population of Gilbert increased 275%. Which of the following are equivalent to 275%?
257
27 1\2
The 2 3/4 or 2.75 is equivalent to 275%.
What is Percentage?The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.
The population of Gilbert increased by 275%. The equivalent to 275% will be:
To express as fraction and decimal, we divide 275 by 100.
= 275/100
= 2 3/4
= 2 + 0.75
= 2.75
So, the equivalent fraction is 275% = 2 3/4 or 2.75.

her initial balance is $2000.
Answer:
Balance of the account after 5 year = $2,577 (Approx)
Step-by-step explanation:
Given:
Initial deposit = $2000

Rounded to the nearest hundredths 27.5=3+5(k-9.5)
Answer:
12 = k
Step-by-step explanation:
Begin: 27.5 = 3 + 5 (k-9.5)
1. Always begin with the parenthesis, which is 5(k-9.5), which comes out to be 5k - 47.5 since the 5 must be multiplied by the k and the -9.5.
Now: 27.5 = 3 + 5k - 47.5
2. Combine the 3 and -47.5, which comes to be -44.5
Now: 27.5 = -44.5 + 5k
3. Add 44.5 to both sides, to make the right side have only the 5k, and the left side to have 72
27.5 + 44.5 = -44.5 + 44.5 + 5k
Now: 72 = 5k
4. Divide both sides by 5 to be left with just what k equals
72/5 = 5k/5
Final Answer: 12 = k
What are the solutions to the equation 0 = x2 - X-6? Select two options
X=-3
X=-2
Ex=0
x=2
X = 3

What is the equation of the graph below?
On a coordinate plane, a curve goes through (0, 0). It has a maximum of 1 and a minimum of negative 1. It goes through one cycle at StartFraction 2 pi Over 3 EndFraction
y = sine (StartFraction x Over 3 EndFraction)
y = sin(3x)
y = sin(0.3x)
y = sine (StartFraction 2 x Over 3 EndFraction)
Answer:
B
Step-by-step explanation:
just took the test on edge
By using the given information, the period particularly, we conclude that the function is y = sin(3x).
What equation describes the given graph?
First, we know that:
The function goes through (0, 0).The maximum is 1The minimum is -1With these 3 considerations, we know that the function is something like:
y = sin(k*x)
So we only need to find the value of k.
We also know that the period of the function is: (2/3)*pi
This means that:
sin(k*(x + (2/3)*pi) = sin(k*x)
Remember that the period of the sine function is 2pi, then:
k*(2/3)*pi = 2pi
k/3 = 1
k = 3
Then the function is:
y = sin(3x).

Bob wants to frame a picture. He needs to know how long to cut
the length and width of the wood for the frame. The length of the
picture is six inches more than the width. If the perimeter of the
picture is 108 inches, what are the length and the width of the
picture?
Answer:
Length = 30 inches
Width = 24 inches
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P) = 2 width + 2 length
Since:
Length (L) = width (w) + 6
Replacing with the values given:
108 = 2w+2 (w+6)
Solving for w:
108 = 2w+2w+12
108-12 =2w+2w
96 =4w
96/4 =w
w= 24 in
Replacing w in the length formula:
L = w+6
L= 24+6 = 30in
