Jenny multiplies the square root of her favorite positive integer by √2. Her product is an integer. a) Name three numbers that could be Jenny's favorite positive integer, and explain why each could possibly be Jenny's favorite integer. b) Suppose Jenny divides the square root of her favorite positive integer by √2. Does she have to get an integer? (Remember, when Jenny multiplies the square root of her favorite integer by √2, she gets an integer.) For part (b), try using each of the numbers you found in part (a) as Jenny's favorite number.
Answers
Answer:
(a) Three numbers that could be Jenny's favorite number are;
2, 8, and 18
(b) Yes
Step-by-step explanation:
(a) Let Jenny's favorite integer be X, we have;
√X × √2 = Y where Y is an integer
Therefore, the square root of Jenny's favorite number has a factor of √2 which gives the possible options as
2 with √2 being the square root
8 with √8 = 2·√2
18 with √18 being 3·√2
(b) By dividing each of the square root of the possible Jenny's favorite number, we have;
i) For the integer 2 we have;
√2/√2 = 1 which is an integer
ii) For the integer 8 we have;
√8/√2 = 2·√2/√2 = 2 which is an integer
ii) For the integer 18 we have;
√18/√2 = 3·√2/√2 = 3 which is an integer

A magazine has 96 pages. There are ads on 75% of the pages. How many pages don't have ads?
Answers
Hey there! :)
Answer:
24 pages.
Step-by-step explanation:
Calculate how many pages 75% of 96 is:
96 × 0.75 = 72 pages.
Find how many pages do not have ads by subtracting the amount that have ads from the total:
96 - 72 = 24 pages.
Therefore, 1/4 of 96 or 24 pages do not have ads.

The half-life of a certain tranquilizer in the bloodstream is 47 hours. How long will it take for the drug to decay to 93% of the original dosage? Use the exponential decay model, Upper A equals Upper A 0 e Superscript kt, to solve.
Answers
Answer:
It will take 4.84 hours for the drug to decay to 93% of the original dosage.
Step-by-step explanation:
We are given that the half-life of a certain tranquilizer in the bloodstream is 47 hours.
The given exponential model is: [tex]A = A_0 e^{kt}[/tex]
Now, we know that A becomes half after 47 hours which means that;
[tex]A = 0.5 A_0[/tex]
Using this in the above equation we get;
[tex]A = A_0 e^{kt}[/tex]
[tex]0.5 A_0 = A_0 e^{(k\times 47)}[/tex] where t = 47 hours
[tex]\frac{0.5 A_0}{A_0} = e^{(47k)}[/tex]
[tex]0.5 = e^{47k}[/tex]
Taking log on both sides we get;
[tex]ln(0.5) = ln(e^{47k})[/tex]
[tex]ln(0.5) =47k[/tex]
[tex]k = \frac{ln(0.5)}{47}[/tex]
k = -0.015
Now, the time it will take for the drug to decay to 93% of the original dosage is given by;
[tex]0.93 = e^{kt}[/tex] where t is the required time
[tex]0.93 = e^{(-0.015 \times t)}[/tex]
Taking log on both sides we get;
[tex]ln(0.93) = ln(e^{-0.015t})[/tex]
[tex]ln(0.93) =-0.015t[/tex]
[tex]t = \frac{ln(0.93)}{-0.015}[/tex]
t = 4.84 hours
Hence, it will take 4.84 hours for the drug to decay to 93% of the original dosage.

Use the given information to draw a box-and-whisker plot of the data set
Minimum – 28
Maximum – 54
Lower Quartile – 32
Upper Quartile – 40
Answers
Answer:
The box-and-whisker plot of this distribution is presented in the attached image to this solution.
Step-by-step explanation:
A box plot gives a visual representation of the distribution of the data, showing where most values lie and those values that greatly differ from the rest, called outliers.
A box and whiskers plot shows 5 major information about the distribution of data. It shows:
- The maximum variable.
- The minimum variable.
- The Median.
- The first quartile.
- The third quartile.
Further info such as the range and Inter quartile range can then be obtained from this 5-number summary.
The elements of the box plot are described thus;
The bottom side of the box represents the first quartile, and the top side, the third quartile. Therefore, the width of the central box represents the inter-quartile range.
The horizontal line inside the box is the median.
The lines extending from the box reach out to the minimum and the maximum values in the data set, as long as these values are not outliers. The ends of the whiskers are marked by two shorter horizontal lines.
Variables in the dataset, higher than Q3+(1.5×IQR) or lower than Q1-(1.5×IQR) are considered outliers and are usually shown using dots above the top whisker or below the bottom whisker.
The required boxplot for this question is given in the attached image to this solution.
The median for the boxplot isn't provided, but it was assumed to be midway between the first and third quartile.

So f(-4) = (-4)^2 + 3(-4) - 1 = 16-12-1 = 3
in the same way f(-3) = -1, f(-2) = -3, f(-1) = -3,
f(0) = -1 and f(1) = 3.
Now plot the points (-4, 3) , (-3, -1) and so on

Which polynomial was factored? x2 – 2x – 8 x2 + 2x – 8 x2 – 2x – 4 x2 + 2x – 4
Answers
Answer:
x² - 2x - 8
Step-by-step explanation:
Algebra tiles are tiles used to represent variables or numbers and are rectangular or square shaped.
1 is labeled + x squared, this gives x²
2 are labeled + x, this gives +x × 2 = +2x
4 tiles below + x squared are labeled negative x, this gives - x × 4 = - 4x
8 tiles below the + x tiles are labeled negative, this gives -1 × 8 = -8
Therefore to get the polynomial that was factored, we add all the terms. This gives :
+x² + (+ 2x) + (-4x) + (-8) = x² + 2x - 4x - 8 = x² - 2x - 8

What is the solution to this system of linear equations? x + y = 4 x − y = 6 A: (4, 6) B: (6, 4) C: (5, −1) D: (−1, 5)
Answers
Answer:
C
Step-by-step explanation:
Given the 2 equations
x + y = 4 → (1)
x - y = 6 → (2)
Add the 2 equations term by term to eliminate y, that is
2x = 10 ( divide both sides by 2 )
x = 5
Substitute x = 5 into either of the 2 equations and evaluate for y
Substituting into (1)
5 + y = 4 ( subtract 5 from both sides )
y = - 1
solution is (5, - 1 ) → C

Answers
Answer:
equilateral triangle ANP inscribed in circle C
regular hexagon AMNBPQ inscribed in circle C
Step-by-step explanation:
By looking through our choices, we can eliminate which choices could be wrong and which choices could be right.
Δ MNQ does form a triangle, however, it DOES NOT form a equilateral triangle.
Δ ANP does form a triangle and it is ALSO an equilateral triangle.
Hexagon AMNBPQ does form a hexagon and it is ALSO a regular polygon as we can see all the sides and angles within the polygon are congruent to one another.
MNPQ does form a quadrilateral, however, it DOES NOT form a square. It is instead a rectangle.
ANBQ does form a quadrilateral, however, it DOES NOT form a square. It is instead a rectangle.
By looking through our observations, we can conclude that Δ ANP and hexagon AMNBPQ are the correct choices.

Answer:
point slope form: y-3=[tex]-\frac{3}5}[/tex](x+2)
slope-intercept form: y=[tex]-\frac{3}{5}[/tex]x+[tex]\frac{9}{5}[/tex]
Step-by-step explanation:
so to find point-slope form, you first have to find the slope of the line
--slope =[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]=[tex]\frac{0-3}{3+2} =-\frac{3}{5}[/tex] (you have to use the two points shown: (-2,3) and (3,0) to plug in for y1, y2, x1, and x2 to find the slope.)
so your slope is [tex]-\frac{3}{5}[/tex].
Now all you have to do is use one of the points (-2,3) to sub in for y1 and x1 in the point-slope form equation.
Therefore, you get y-3=[tex]-\frac{3}{5}[/tex](x+2) for point-slope form.
Now for slope-intercept form, you already have the slope because you found it to complete the equation for point slope form
slope = [tex]-\frac{3}{5}[/tex]
Now slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.
So, far we have y=[tex]-\frac{3}{5}[/tex]x+b
the easiet point to use for the x and y values is (3,0)
so, lets substitute: 0=[tex]-\frac{3}{5}[/tex](3)+b, which becomes 0=[tex]-\frac{9}{5}[/tex]+b
add [tex]-\frac{9}{5}[/tex] to both sides to get b=[tex]\frac{9}{5}[/tex]
Now you have both the slope and the y-intercept so you can now write the line in slope-intercept form.
You get [tex]y=-\frac{3}{5}x +\frac{9}{5}[/tex].

Answers
Answer:
See Explanation
Step-by-step explanation:
The question didn't specify if letter can be repeated or not;
I'll solve for both;
Given
Number of Letters = 26
Number of squared = 4
If Repetition is allowed;
The four squares can take any of the 26 letters in any order
The first letter can be any of 26; Same with the second, third and fourth letters;
Number of Arrangement = 26 * 26 * 26 * 26
Number of Arrangement = 26⁴
Number of Arrangement = 456976
If Repetition is not allowed;
The first square can be filled with any of the 26 letters;
The second can take any of (26 - 1) letters
The third can take any of (26 - 2) letters
The fourth can take any of (26 - 3) letters
Number of Arrangement = 26 * (26 - 1) * (26 - 2) * (26 - 3)
Number of Arrangement = 26 * 25 * 24 * 23
Number of Arrangement = 358800
