Answer:
YET
Step-by-step explanation:
TO DECRYPT DKA USING THE CAESAR SHIFT CIPHER STARTING WITH 5 SHIFTS.
TO DO THIS DECRYPTION, WE'RE GOING TO LOOP THE ALPHABETS.
D = LOOPING THIS LETTER 5 TIMES, WE HAVE C - B - A - Z - Y.
SO, D IS DECRYPTED AS Y
GOING FURTHER, THE ENCRYPTION SHIFTS BY AN ADDITIONAL SPACE. THIS MEANS, IF THE FIRST "Y" WAS ENCRYPTED IN 5 SPACES TO GET D, AND AN ADDITIONAL SPACE WAS ADDED TO THE NEXT ALPHABET, IT BECOMES 6.
K IS THEN DECRYPTED AS
K = J - I - H - G - F - E
K IS DECRPYTED AS E
GOING FURTHER, THE NEXT WAS ENCRYPTED WITH AN ADDITIONAL SPACE EVEN MORE, SO, A IS DECRPYTED AS
A = Z - Y - X - W - V - U - T.
THUS, DKA IS DECRYPTED AS YET
Suppose $x$ and $y$ are integers such that $xy+5x+4y=-5$. Find the greatest possible value of $y$.
Answer:
10
Step-by-step explanation:
xy + 5x + 4y = -5
(x + 4) y + 5x = -5
(x + 4) y = -5x − 5
y = -5 (x + 1) / (x + 4)
For y to be large as possible, (x + 1) / (x + 4) must be negative. That means -4 < x < -1. So x is either -2 or -3.
The possible values of y are:
y = -5 (-2 + 1) / (-2 + 4) = 5/2 (not an integer).
y = -5 (-3 + 1) / (-3 + 4) = 10.

the point-slope form of the equation that passes through (-4, -3) and (12, 1) is y - 1 = 1/4(x-12). what is the standard form of the equation for this line?
A) x-4y=8
B) x-4y=2
C) 4x-y=8
D) 4x-y=2
Answer:
A
Step-by-step explanation:
So we know that the point-slope form of the line that passes through the points (-4,-3) and (12,1) is:
[tex]y-1=\frac{1}{4}(x-12)[/tex]
And we want to convert this to standard form.
The standard form of a linear equation is:
[tex]Ax+By=C[/tex]
Where A, B, and C are integers, and, traditionally, A is positive.
So, first, multiply everything by 4 to remove the negative:
[tex]4(y-1)=4(\frac{1}{4}(x-12))[/tex]
Distribute the left. The right cancels:
[tex]4y-4=x-12[/tex]
Add 4 to both sides. The left cancels:
[tex]4y=x-8[/tex]
Subtract x from both sides:
[tex]-x+4y=-8[/tex]
As I mentioned previously, the coefficient of A tends to be positive. So, divide everything by -1:
[tex](-x+4y)/-1=(-8)/-1[/tex]
Simplify:
[tex]x-4y=8[/tex]
So, our answer is A
And we're done!
Let A and B be n-by-n matrices in R^n, and let c be a real number. Which of the following statements about trace is not necessarily true? a. tr(A+B) = tr(A) + tr(B) b. tr(AB) = tr(BA) c. tr(AB) = tr(A)tr(B) d. tr(CA) = ctr(A)
Answer:
c. tr(AB) = tr(A)tr(B)
Step-by-step explanation:
The trace of a matrix is only valid for a square matrix, that is a n by n matrix. The trace of a matrix is the sum of all its diagonal elements. The following properties of trace holds for a matrix A and B with size n by n and a real number c.
i) The trace sum of two matrix is equal to the sum of their individual traces. That is:
tr(A + B) = tr(A) + tr(B)
ii) The trace of the product of a scalar and a matrix is the same as the product of the scalar and the trace of the product, that is:
tr(cA) = ctr(A)
iii) The trace of a transpose of a matrix is equal to the trace of the matrix, that is:
[tex]tr(A^T)=tr(A)[/tex]
iv) The trace of a product of matrix is given as:
tr(AB) = tr(BA)
Answer:
c. tr(AB) = tr(A)tr(B)

B. You are given nine stones which look and feel identical. One of them contains a valuable gem worth $250,000 and is actually slightly heavier than the other eight (but not enough to detect by lifting by hand). If you identify the gemstone it is yours to keep. You have a balance scale, (see diagram) which you can use exactly two times. Once you have used the scale twice you never get another opportunity. How can you be certain to find the stone contains the gem. (If you guess at any point you lose your chance to win the gem stone.)
Answer:
Separate the stones into 3 groups of 3.
Let's call each the three groups A, B, and C.
1) Place group A and group B on the two plates of the scale. There are two possible outcomes i) and ii) below:
i) The groups have different weights. A is heavier than B or B is heavier than A. Take the heavier group. Place two stones from this group on the scale. If one is heavier than the other, this is it. If they are equal, the stone not on the scale is it.
ii) Groups A and B have equal weights. The heavier stone in in group C. Using group C, place two stones from this group on the scale. If one is heavier than the other, this is it. If they are equal, the stone not on the scale is it.

Find a vector of magnitude 3 in the direction of v = 10i - 24k. The vector is Oi-Oj+k (Simplify your answer. Use integers or fractions for any numbers in the expression).
Given :
A vector v = 10i - 24k.
To Find :
A vector of magnitude 3 in the direction of v = 10i - 24k.
Solution :
Unit vector in the direction of vector v is :
[tex]\^{v}=\dfrac{v}{|v|}\\\\\^{v}=\dfrac{10i-24k}{\sqrt{10^2+24^2}}\\\\\^{v}=\dfrac{10i-24k}{26}[/tex]
Now , vector of magnitude 3 in direction v is :
[tex]r=3 \^{v}\\\\r=3\times \dfrac{ (10i-24k)}{26}\\\\r=\dfrac{3}{13} (5i-12k)[/tex]
Hence , this is the required solution .
The vector of magnitude 3 in the direction of given vector is, [tex]\frac{30i-72k}{26}[/tex]
Unit vector :First we have to calculate unit vector of given vector.
Given vector, [tex]v=10i-24k[/tex]
Unit vector of vector v is,
[tex]v=\frac{10i-24k}{\sqrt{(10)^{2}+(24)^{2} } }\\ \\v=\frac{10i-24k}{\sqrt{100+576} }=\frac{10i-24k}{26}[/tex]
For vector have magnitude 3 is,
[tex]v=3(\frac{10i-24k}{26} )=\frac{30i-72k}{26}[/tex]
The vector of magnitude 3 in the direction of given vector is, [tex]\frac{30i-72k}{26}[/tex]

Twenty-three student compete in a math competition in which the top three studentsare recognized with trophies for first, second, and third place. How many different outcomes arethere for the top three places?
Answer:
10626 ways
Step-by-step explanation:
Given
Number of students = 23
Prizes = 3
Required
Number of different outcomes for the top 3
This question will be solved using permutation formula because it implies selection of 3 students from 23
[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]
Where n = 23 and r = 3
The formula becomes
[tex]^{23}P_3 = \frac{23!}{(23-3)!}[/tex]
[tex]^{23}P_3 = \frac{23!}{(20)!}[/tex]
[tex]^{23}P_3 = \frac{23!}{20!}[/tex]
[tex]^{23}P_3 = \frac{23 * 22 * 21 * 20!}{20!}[/tex]
[tex]^{23}P_3 = 23 * 22 * 21[/tex]
[tex]^{23}P_3 = 10626[/tex]
Hence, there are 10626 ways
Write an expression that represents the volume of a rectangular-shaped box with a length 3 inches less than its height and a width 4 inches greater than its height
Answer: h(h-3)(h+4)
Step-by-step explanation:
To find the volume of rectangular-shaped box we will have to multiply the length by the width by the height.
Given the statements we can determine the length with the equation
L = h -3 where l is the length and h is the height.
the width can also be represent by the equation
w = h + 4
The height is is h and the length is h- 3 and the width is also h+4 so the expression will be h(h-3)(h+4)
