Hello! :)
Answer:
[tex]\huge\boxed{x = (\frac{b}{a})(P+c)}[/tex]
[tex]\frac{a}{b}x - c = P[/tex]
Solve for x:
Begin isolating the variable by adding "c" to both sides:
[tex]\frac{a}{b}x - c + c= P + c[/tex]
[tex]\frac{a}{b}x = P+ c[/tex]
Divide both sides by a/b, or multiply by the reciprocal (b/a)
[tex](\frac{b}{a}) \frac{a}{b}x = (\frac{b}{a})(P + c)[/tex]
Therefore:
[tex]x = (\frac{b}{a})(P + c)[/tex]
Decrypt the word DKA if it was encrypted using an alphabetic Caesar shift cipher that starts with shift 5 (mapping A to F), and shifts one additional space after each character is encrypted. Use only capital letters in your answer.
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

Round to the nearest eurocent per kilo
Answer:
2 eurocent per kilo
Step-by-step explanation:
Since we are already given the conversion units, we only simply need to divide/multiply and cancel out units.
Dollars and dollars cancel out.
We are left with eurocent.
Pounds and pounds cancel out.
We are left with kilograms.
We do want eurocent over kilograms.
0.89(0.93) = 0.8277/0.4536 = 1.82474
Since we want to round it to the nearest cent, we round up because 8 ≥ 5:
1.82474 ≈ 2
Triangle RST has the vertices R(2, 3), S(-2, 1), and T(-1, 5). What are the coordinates after the two transformations: Reflection over the y-axis and rotation at 180 degrees around the origin
Answer:
R''(2,-3), S''(-2,-1) and T'(-1,-5).
Step-by-step explanation:
The given vertices of triangle are R(2, 3), S(-2, 1), and T(-1, 5).
Reflection over the y-axis:
[tex](x,y)\to (-x,y)[/tex]
Using this rule, the vertices after reflection are
[tex]R(2,3)\to R'(-2,3)[/tex]
[tex]S(-2,1)\to S'(2,1)[/tex]
[tex]T(-1,5)\to T'(1,5)[/tex]
Rotation at 180 degrees around the origin.
[tex](x,y)\to (-x,-y)[/tex]
Using this rule, the vertices after reflection are
[tex]R'(-2,3)\to R''(2,-3)[/tex]
[tex]S'(2,1)\to S''(-2,-1)[/tex]
[tex]T'(1,5)\to T''(-1,-5)[/tex]
Therefore, the coordinates of vertices after the two transformations are R''(2,-3), S''(-2,-1) and T'(-1,-5).

Graph the equation.
y= 1/8(x-6)(x+2)
Answer:
see below
Step-by-step explanation:
See the attachment.
The graph will have x-intercepts where the factors are zero, at x=6 and x=-2. The y-intercept will be the value when x=0: (1/8)(-6)(2) = -1.5.
The axis of symmetry is halfway between the zeros, so is x = (6-2)/2 = 2.
The minimum value of the function is at x=2, so is ...
y = (1/8)(2 -6)(2 +2) = 1/8(-16) = -2
Other y-values can be found by substituting other x-values in the equation and evaluating it. Rather than go to that trouble, I prefer to use a graphing calculator.

in which number does the digit 7 have a value that is 10 times as great as the digit 7 in the number 0.975
a. 676 9
b. 7.99
c. 0.73
d. 8.457
The answer is 0.73 because in 0.975 the value of digit 7 is 7/100 ,10 times of 7/100 is 7/10 and the value of 7 in 0.73 is 7/10 ;.tenth value.
The value of each digit in a number is known as the place value. The number is 0.73. The correct option is C.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10The value of digit 7 in the number 0.975 is hundredth. Therefore, the digit 7 in the number 0.975 is equal to 7/100.
Now, if the number is 10 times as great as digit 7 in 0.975. Therefore,
7/100 x 10 = 7/10 = 0.7
Thus, the number in which digit 7 have a value that is 10 times as great as the digit 7 in the number 0.975 is the number that is at the first place after the decimal.
Hence, the number is 0.73.

In a manufactory, there are two types of spoilages. It is found that 5% of spoilages are due to transformer spoilage, 8% are due to line spoilage and 3% involve both problems. (a) Are the two types of spoilages independent or not? Justify your answer. (b) What is the probability that: i- line spoilage given that there is transformer spoilage ii- Transformer spoilage but not line spoilage. iii- Transformer spoilage given that there is no line spoilage iv- Neither transformer spoilage nor there is no line spoilage v- Either transformer spoilage or there is no line spoilage
Answer:
The events are independent.Their conditional probability is equal to the probability of an event .
2) The probability that there is line spoilage given that there is transformer spoilage=0.08
- Transformer spoilage but not line spoilage=0.046
Transformer spoilage given that there is no line spoilage = 0.05
- Neither transformer spoilage nor there is no line spoilage =0.03
v- Either transformer spoilage or there is no line spoilage = 0.97
Step-by-step explanation:
Let A be an event that the spoilage is due to transformers so
P(A) = 5% = 5/100 or 0.05
Let B be an event that the spoilage is due to line so
P(B) = 8% = 8/100 or 0.08
Let C be an event that the spoilage is due to both then
P(C) = 3% = 3/100 or 0.03
1) Independence
For events to be independent their joint probability is given by
P(A) = P(A∩B)/ P (B) By Law of independence
P(A∩B)= P(A/B)P(B)
P(A∩B) = 5/100 *8/100=40/10000= 4/1000
P(A) = 5/100
P(A/B) =P(A∩B)/ P (B)
= 4/1000/8/100= 1/20
P(A)= P(A/B)
5/100 is equal to 1/20
The events are independent.Their conditional probability is equal to the probability of an event
2) The probability that there is line spoilage given that there is transformer spoilage
P(B/A)= P(A∩B)/ P (A) = 4/1000/5/100= 4/50= 2/25=0.08
Which is again equal to probability of event B.
- Transformer spoilage but not line spoilage
P(A∩1-B)= 5/100*92/100= 460/10000=0.046
Transformer spoilage given that there is no line spoilage
P(A/1-B) =P(A∩1-B)/ P (1-B)
= 5/100*92/100/92/100= 5/100 = 0.05
- Neither transformer spoilage nor there is no line spoilage
1-P(A) +P(1-B)= 1-(5/100+92/100)= 3/100= 0.03
v- Either transformer spoilage or there is no line spoilage
P(A)+P(1-B)= 5/100+92/100= 97/100= 0.97
Bob runs four laps. The average speed for the first lap is 12 km/h, the average speed for the second lap is 10km/h, the average speed for the third lap is 8km/h and the average speed for the last lap is 6km/h. What is average speed for the four laps
Answer:
The average speed for the four laps is 9 km/h.
Step-by-step explanation:
The average speed of the four laps can be calculated as follows:
[tex] \overline{v_{T}} = \frac{\overline{v_{1}} + \overline{v_{2}} + \overline{v_{3}} + \overline{v_{4}}}{4} [/tex]
Where:
[tex]\overline{v_{1}}[/tex]: is the average speed for the first lap
[tex]\overline{v_{2}}[/tex]: is the average speed for the second lap
[tex]\overline{v_{3}}[/tex]: is the average speed for the third lap
[tex]\overline{v_{4}}[/tex]: is the average speed for the fourth lap
Hence, the average speed for the four laps is:
[tex] \overline{v_{T}} = \frac{12 km/h + 10 km/h + 8 km/h + 6 km/h}{4} [/tex]
[tex] \overline{v_{T}} = 9 km/h [/tex]
Therefore, the average speed for the four laps is 9 km/h.

Find the equation of the line parallel to y= -5x-3 that passes through the point ( -5, -4). If possible, write the equation in slope-intercept form.
Answer:
y = -5x - 29
Step-by-step explanation:
y-intercept form is y = mx +b,
m is slope, for parallel line slope is the same, so m= -5
y = -5x + b
To find b, we need to use the point (-5, - 4).
- 4 = -5*(-5) + b
- 4 = 25 + b
b = - 29
y = -5x - 29
Find the limit. Use l'Hospital's Rule if appropriate. If there is a more elementary method, consider using it. lim x→1 3x x − 1 − 3 ln(x)
Answer:
3/2Step-by-step explanation:
Given the limit of a function expressed as [tex]\lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})[/tex], we are to evaluate it. To evaluate it, we will simply substitute x = 1 into the function since the variable x tends to 1.
[tex]\lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})\\\\= (\dfrac{3(1)}{1-1} - \dfrac{3}{ln1})\\\\= \dfrac{3}{0} - \dfrac{3}{0}\\\\= \infty - \infty (ind)[/tex]
Since we got an indeterminate function, we will find the LCM of the function and solve again.
[tex]= \lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})\\\\= \lim_{x \to 1} \dfrac{3xlnx-3(x-1)}{(x-1)lnx}\\\\\\= \dfrac{3(1)ln(1)-3(1-1)}{(1-1)ln1}\\\\= \frac{3(0)-3(0)}{0(0)} \\\\= \frac{0}{0} (ind)[/tex]
Applying L'hospital rule;
[tex]\frac{x}{y} = \lim_{x \to 1} \dfrac{d/dx(3xlnx-3(x-1))}{d/dx((x-1)lnx)}\\\\= \lim_{x \to 1} \dfrac{3x(\frac{1}{x})+ 3lnx-3)}{(x-1)\frac{1}{x} +lnx}\\\\= \lim_{x \to 1} \dfrac{3 + 3lnx-3}{(x-1)\frac{1}{x} +lnx}\\\\= \frac{3ln1}{(1-1)\frac{1}{1} +ln1}\\\\= \frac{0}{0} (ind)[/tex]
Applying L'hospital rule again;
[tex]= \lim_{x \to 1} \dfrac{\frac{d}{dx} (3lnx)}{\frac{d}{dx} ((x-1)\frac{1}{x} +lnx)}\\\\= \lim_{x \to 1} \dfrac{\frac{3}{x} }{(x-1)\frac{-1}{x^2} + \frac{1}{x} +\frac{1}{x} }\\\\= \dfrac{\frac{3}{1} }{(1-1)\frac{-1}{1^2} + \frac{1}{1} +\frac{1}{1} }\\\\= \frac{3}{0(-1)+2}\\ \\= \frac{3}{2-0}\\ \\= 3/2[/tex]
Hence the limit of the function is 3/2.
