(D) V512 is not a rational number.
What are rational numbers?A rational number is any number that can be written as a fraction and has both the numerator (the top number) and the denominator (the bottom number) being integers and not equal to zero. In other words, a rational number is p/q, where p and q are both integers and q = 0. A rational number is one that has the form p/q, where p and q are integers and q is greater than zero. Some rational number examples include 1/3, 2/4, 1/5, 9/3, and so on.Since, numbers in options (A), (B), and (C) can be written in fractions, then these numbers are rational numbers.
V512 cannot be written in fractions as we don't know what V is.So, V512 is not rational.Therefore, (D) V512 is not a rational number.

An isolated agricultural country has two distinct regions: a lowland plain and an upland of rugged hills. On one unit of land on the PLAIN, a farmer can raise 10 bushels of grain or graze 10 sheep. On one unit of land in the HILLS, a farmer can raise 2 bushels of grain or graze 4 sheep.
Determine which region has the absolute advantage for sheep production. Explain your answer.
Hills region has the advantage for sheep production because when a farmer raised 2 bushels of grain, then gaze 4 sheep.
The most popular animal fiber is sheep's wool, which is often gathered by shearing. In Commonwealth nations, ovine meat is referred to as lamb when it comes from younger animals and mutton when it comes from older ones; in the United States, meat from both older and younger animals is often referred to as a lamb.
Today, sheep are still farmed for their meat and wool, as well as on occasion for their pelts, as dairy animals, or as scientific model organisms. Most of the world's populated areas engage in sheep farming, which has been a foundational activity for several civilizations.

To test the ability of mechanics to identify simple engine problems, a car with a single such problem was taken in turn to 72 different car repair facilities. Only 42 of the 72 mechanics who worked on the car correctly identified the problem. Does this strongly indicate that the true proportion of mechanics who could identify this problem is less than 0.75?
a) Perform the appropriate test of hypothesis using = 0.01. Clearly show the eight (8) steps
Using the z-distribution, it is found that since the p-value is less than 0.01, there is strong indication that the true proportion of mechanics who could identify this problem is less than 0.75.
What are the hypotheses tested?At the null hypotheses, it is tested if there is not enough evidence that the proportion is less than 0.75, that is:
[tex]H_0: p \geq 0.75[/tex]
At the alternative hypotheses, it is tested if there is enough evidence that the proportion is less than 0.75, that is:
[tex]H_1: p < 0.75[/tex]
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.For this problem, the parameters are given as follows:
[tex]n = 72, \overline{p} = \frac{42}{72} = 0.5833, p = 0.75[/tex]
Hence the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.5833 - 0.75}{\sqrt{\frac{0.75(0.25)}{72}}}[/tex]
z = -3.27.
What is the p-value of the test?Considering a left-tailed test, as we are testing if the proportion is less than a value, with z = -3.27, the p-value is < 0.01.
Since the p-value is less than 0.01, there is strong indication that the true proportion of mechanics who could identify this problem is less than 0.75.

L = 20,000 = loan amountP = 475 = monthly paymenti = 0.0425/12 = 0.0035417 approximately is the decimal form of the monthly interest raten = unknown number of monthsLet A = P/i = 475/0.0035417 = 134116.384787 approximately
Then,
[tex]n = \frac{\text{Ln}(A) - \text{Ln}(A-L)}{\text{Ln}(1+i)}\\\\n \approx \frac{\text{Ln}(134116.384787) - \text{Ln}(134116.384787-20000)}{\text{Ln}(1+0.00354)}\\\\n \approx \frac{11.80646 - 11.64497}{0.00353}\\\\n \approx \frac{0.16149}{0.00353}\\\\n \approx 45.74788\\\\n \approx 46[/tex]

An accounting machine operator wanted to divide a 65 minute job between two identical machines so that one machine would take one and a half times as long as the other. How much time was taken by the machine doing the longer job?
The slow machine did the job is 39 minutes as calculated with the help of a linear equation in one variable.
A linear equation in one variable is given by the combination of the variable with constants and coefficients such that a unique relationship is established between the terms.
Let us consider the faster machine takes x minutes the finish the job.
Hence the slower machine will take one and a half times .
∴ slower machine takes 1.5 x minutes.
Total time taken by the two machines = x + 1.5x = 2.5 x
But together the two machines will take 65 minutes to complete the job .
So now we form a linear equation with the variable x to solve for the value of x
∴ 2.5 x = 65
or, x = 65 ÷ 2.5
or, x = 26 minutes
Therefore the faster machine takes 26 minutes.
Hence the slower machine will take 1.5 x = 1.5 × 26 = 39 minutes.

if a ball is thrown into the air with a velocity of 20 ft/second it's height in feet and seconds is given by f(t) = 20t - 10t^2. find average velocity for the time period t0 = 1 to t=2
The average velocity is -10 ft/s.
What is Average velocity?Average velocity is just the average speed with a direction. If a trip starts and ends at the same point, the total displacement is zero, so the average velocity is zero.
For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph).
Given:
f(t) = 20t - 10t²
Now, from t=1 to t=2
f(1)= 20*1 - 10 * 1*1
f(1)= 10
and, f(2)=20*2-10*2*2
f(2)= 40-40
f(2)=0
Now,
Average velocity:
v = ( 0-10 ) / ( 2- 1 )

All calculations for answer in picture form
Answer:
There are 88 square inches needed to cover a box that is 4 in • 6 in • 2 in
Step-by-step explanation:
In order to cover the box you need to find the surface area of it. The formula for finding the surface area of a rectangular prism is 2 • ((w•l) + (h•l) + (h•w)). The dimensions of the box is 4 inches in length, 6 inches in width, and 2 inches in height.
Apply the dimensions into the formula of the rectangular prism when the numbers are plugged in it results in 2 ( (6•4) + (2•4) + (2•6) )Multiply the dimensions the area of length• width is 24 (six times four is twenty-four), the area of height•width is 8 (two times four is eight), and the area of height•width is 12 (two times six is twelve). At the end of this step it becomes 2 • ((24) + (8) + (12))Add all the numbers inside the parentheses then it becomes 2 • (44) Multiply the number in parentheses by 2 the final answer is 88 in²Use algebraic methods to prove that the given function has an x-intercept that is equal to its y-intercept. In your final
answer, include all of your calculations.
y= x/x^2-1
Step-by-step explanation:
the y-intercept is the y value when x = 0.
the x-intercept is the x value when y = 0.
for x = 0
y = 0 / (0² - 1) = 0/-1 = 0
this automatically answers also our question about the x value when y = 0. we found this out already with the y-intercept.
the interception point with both coordinate axis is (0, 0).

ABCD is a rectangle.
so, it has 2 pairs of equal and parallel sides.
all 4 angles are 90°.
both diagonals are equally long and intersect each other at their midpoint. so, all 4 half-diagonal segments are equally long.
(1)
2x + 4y = 4x - y = 36/2 = 18 cm
we can split this into 2 equations
2x + 4y = 4x - y
5y = 2x
x = 5y/2
and e.g.
4x - y = 18
now we use the first equation in the second
4(5y/2) - y = 18
20y/2 - y = 18
10y - y = 18
9y = 18
y = 2
x = 5y/2 = 5×2/2 = 5
(2)
I cannot draw here, but the shortest distance between a point and a line is always a height (a line segment from the point meeting it intersecting the line at a right angle, 90°).
(3)
e.g.
AE, AD/2 and the drawn height from E to AD create a right-angled triangle.
we know AD/2 = 15 cm
from (1) we know AE = 4x - y = 4×5 - 2 = 20 - 2 = 18 cm.
the height E to AD we get via Pythagoras
AE² = (AD/2)² + height²
height² = AE² - (AD/2)² = 18² - 15² = 324 - 225 = 99
height = sqrt(99) = sqrt(9×11) = 3×sqrt(11)
remember trigonometry ?
this height = sin(theta) × AE
sin(theta) = height / AE = 3×sqrt(11) / 18 = sqrt(11)/6 =
= 0.552770798...
theta = 33.55730976...° ≈ 34°
