If it is possible to label each element of an infinite set S with a finite string of keyboard characters, from a finite list characters, where no two elements of Shave the same label, then S is a countably infinite set. Use the above statement and prove that the set of rational numbers is countable.
A. We can label the rational numbers with strings from the set (0, 1, 2, 3, 4, 5, 6, 7, 8, 9,-) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.
B. We can label the rational numbers with strings from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,/,-) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.
C. We can label the rational numbers with strings from the set (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 1) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.
D. We can label the rational numbers with strings from the set (1, 2, 3, 4, 5, 6, 7, 8, 9,/ -) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.
Answer:
D. We can label the rational numbers with strings from the set (1, 2, 3, 4, 5, 6, 7, 8, 9, / -) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.
Step-by-step explanation:
The label numbers are rational if they are integers. The whole number subset is rational which is written by the string. The sets of numbers are represented in its simplest forms. The rational numbers then forms numbers sets which are countable.

A bit stuck on how to do this
Answer:
x = 40°
Step-by-step explanation:
Two sides are the same length, so the angles opposite them are the same size.
The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.
Since the remaining two angles are congruent, each is 40°.
A young person decides to put aside some money for retirement by putting $1,000 in a 30-year savings bond that pays 3.0% simple interest per year. The interest compounds. How much money will the person have after 30 years?
Answer:
2427.26 $
Step-by-step explanation:
Just use this formula when you have such type of problems:
N = N° (1 + %)^t
Where N = final amount
N°= initial amount
t = peroid of time
Now let's solve:
N = 1000(1 + 0.03)^30
N = 2427.26

The pie chart below represents the vehicle types owned by families. If the total number of people surveyed is 1000, approximately how many own a van?
Answer:
500 families
Step-by-step explanation:
We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,
0.50⋅1000=500
About 500 families own a van.

Find the slope of the line through the given points (-7, 7), (-1,10)
Answer:
The slope would be 1/2.
Step-by-step explanation:
When solving questions like these, make sure to plug in the points into the formula: [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}} = slope[/tex] . y2 would stand for the y coordinate of the second point, y1 would stand for the y coordinate of the first point. While x2 would stand for the x coordinate of the second point and x1 for the x coordinate of the first point. Once plugged in, it should look like this: [tex]\frac{10-7}{-1-(-7)}[/tex]. That should then give you the slope of 1/2. Hope this helps!! :D

NEED HELP PLEASE ! WILL MARL BRANIEST IF RIGHT
Answer:
-9, -2, 14
Step-by-step explanation:
-1 is < 0 so plug it into the first function.
8(-1) -1 = -9
0 is ≥ 0 so plug it into the second function
8(0)-2 = -2
2 is ≥ 0 so plug it into the second function
8(2) - 2 = 14

what is the area of a triangular prism with 1 1 1.2 1.2 and0.8
Find the area. Use 3.14 for pi.
Round to the nearest tenth if necessary. A circle with a radius of 48mm
Answer:
7234.56
Step-by-step explanation:
A = pi * r * r
A = 3.14 * 48 * 48
A = 7234.56

Here we've being provided with the information that is we have a circle with a radius of 48cm. And we've been asked to find out the area of circle.
Radius (r) = 48cm Pie (π) = 3.14 Area (a) = ?The standard formula to calculate area of circle is given by,
[tex]:\implies\tt{a = \pi {r}^{2} }[/tex]
[tex]:\implies\tt{a = 3.14 \times 48 \times 48}[/tex]
[tex]:\implies\tt{a = 3.14 \times 2304}[/tex]
[tex]:\implies\tt{a = 7234.56}[/tex]
The area of circle is 7234.56.(PS: We have assumed 48cm instead of 48mm given in question)

What are the solutions of 2x2 + 8x + 26 = 0?
Step-by-step explanation:
2×2 + 8x + 26 =0
4 + 8x + 26 =0
4 + 26 = 0-8x
30 = 8x
divide both sides by th coefficient of x
30

Answer:
1) No. 2)No. 3)More than one, 4) Unique. 5)More than one. 6)More than one
Step-by-step explanation:
For the first two are not a triangle is because when adding the shortest two side of the triangle, it has to be longer than the longest one. 3) is because it only define 3 angles, but it can be different length, same for 5) and 6), then 4) is unique as the when defining 3 lines, it only has one combination, and the angles will be fixed.
