The required number is rounded off as 18.3 is 18.29 and 18.299.
Given that,
To determine the two different numbers that when rounded to the nearest tenth with give you 18.3.
What do rounding values mean?
The rounding of values is the replacement of a number with an approximate value that has a more transient, straightforward, or direct expression.
When a number is rounded to the closest tenth, the result is 18.3, which implies that there must be a number greater than 5 in each position following the tenth position after the decimal place.
Thus, 18.29 and 18.299 are the numbers.
The required number is then rounded off to 18.3, which is 18.29 and 18.299, respectively.

Given: cos θ = 3/5 and θ is located in the fourth quadrant;
find cos2θ AND θ/2
The value of the trigonometric functions cos 2θ and cos 0.5θ for the given angle are - 7 / 25 and - 2√5 / 5, respectively.
How to determine the exact values of trigonometric expressions
In this problem we must determine the cosine of the double angle and half angle based on the exact values of the cosine of an angle and the quadrant location of the angle.
Cosine is a function between - 1 and 1 and whose period is 2π (360°), positive when angle is either on first quadrant (0 < θ < 0.5π) or on fourth quadrant (1.5π < θ < 2π). In addition, sine function is positive on first quadrant and negative on fourth quadrant.
The required trigonometric formulas in terms of trigonometric function cos θ are described below:
sin θ = √(1 - cos² θ)
cos 2θ = cos² θ - sin² θ
cos 0.5θ = ± √ [(1 + cos θ) / 2]
First, determine the exact value of sine:
sin θ = - √[1 - (3 / 5)²]
sin θ = 4 / 5
Second, determine the exact value of cosine of the double angle:
cos 2θ = (3 / 5)² - (4 / 5)²
cos 2θ = - 7 / 25
Third, determine the exact value of cosine of the half angle:
cos 0.5θ = - √[(1 + 3 / 5) / 2]
cos 0.5θ = - 2√5 / 5

Answer:
Step-by-step explanation:
Fraction: 3/10 decimal: 0.30
Answer:
Fraction: 3/10; Decimal: 0.3
Step-by-step explanation:
A). When trying to find the fraction of percent, the denominator is always 100 since the word percent itself states "per-cent," meaning per 100 as a cent can go up to a maximum of 100 before being converted into a dollar. Therefore, the fraction then becomes 30/100, however, we need to simplify it as stated by the question and we can easily do that by canceling out one zero on the numerator and the denominator, giving us the simplified fraction of 3/10.
B). Now, to find the decimal, we just have to divide the numerator by the denominator and dividing 3 by 10 gives us a decimal of 0.3. This decimal has already been rounded to the nearest hundredth since it is in the tenths place, so thus, there is a continuation of zeroes after the 3 infinitely. Therefore, the decimal rounded to the nearest hundredth is 0.3.

Find the 5 number summary for the data shown 5 number summary:
The five number summary of the given data is the minimum value = 20, maximum value = 100, median = 69.5, Q1 = 48, and Q3 = 89.
A number summary consists of five values: the most extreme values in the data set (the maximum and minimum values), the lower and upper quartiles, and the median. In order to find the five number summary,
1. Arrange the given data in ascending order. In the given case, the data is already in ascending order.
2. Determine the minimum and maximum value for the data set. In the given case, the minimum value is 20 and maximum value is 100.
3. Determine the median of the data set. The median refers to the middle number of the data set. If the data is an even set of numbers, the middle two terms are averaged. In the given case, there are 14 numbers, hence the median is an average of 7th and 8th term.
Median = (69 + 70)/2 = 69.5
4. Determine the lower quartile (Q1) and upper quartile (Q3). The Q1 and Q3 are the middle term of the lower and upper range respectively.
For the lower range, 20, 33, 43, 48, 64, 68, 69, the middle term is 48. Hence Q1 = 48.
For the upper range, 70, 72, 83, 89, 96, 99, 100, the middle term is 89. Hence Q3 = 89.

The percentage by which the price of the car went up from the original price is 60% (third option)
What is the percent increase?The first step is to determine the price of the car after the percentage increase. Percentage is the fraction of a number as a value out of 100. The sign that is used to represent percentage is %.
Price of the car after the percentage increase = (1 + percent increase/100) x original cost of the car
Price of the car after the percentage increase = (1 + 20/100) x 20,000
Price of the car after the percentage increase = (1 + 0.2) x 20,000
Price of the car after the percentage increase = 1.2 x 20,000 = $24,000
Price after the $8,000 increase = $24,000 + 8,000 = $32,000

Based on the quantity equation, if m = 8,000, p = 3, and y = 12,000, then v = 0.22
B. The Quantity Equation is a relationship between the money supply (m), the price level (p), and the level of economic activity (y), represented as m = py.
In this case, since we know that m = 8,000, p = 3, and y = 12,000, we can use this equation to solve for v. By dividing both sides of the equation by y, we get m/y = pv. Now we know m/y=8,000/12,000=0.66, and p=3, so we can solve for v by dividing m/y by p, which results in v=0.66/3=0.22 (when rounded) .
This means that the velocity of money (v) is .22, it means that each unit of money is used 0.22 times per year to purchase goods and services.

How do you find the horizontal and vertical asymptotes of a limit?
Vertical and horizontal asymptotes are the two different forms of asymptotes. In order to help us comprehend the horizontal asymptotes fully, we provide an example. We just assess the function's limit as it approaches infinity and again as it approaches negative infinity to discover horizontal asymptotes.
Horizontal Asymptotesthe equation limx→cf(x)=L , both c and L were numbers. In this section we relax that definition a bit by considering situations when it makes sense to let c and/or L be "infinity.''
consider f(x)=1/x2 , as shown in Figure 1.30. Note how, as x approaches 0, f(x) grows very, very large. It seems appropriate, and descriptive, to state that
[tex]\lim_{x \to \infty} \frac{1}{x^{2} }[/tex]
Vertical AsymptotesIf the limit of f(x) as x approaches c from either the left or right (or both) is ∞ or −∞ , we say the function has a vertical asymptote at c .
When a rational function has a Vertical asymptote at x=c , we can conclude that the denominator is 0 at x=c . However, just because the denominator is 0 at a certain point does not mean there is a vertical asymptote there. For instance, f(x)=(x2−1)/(x−1) does not have a vertical asymptote at x=1 , . While the denominator does get small near x=1 , the numerator gets small too, matching the denominator step for step. In fact, factoring the numerator, we get
f(x)=(x−1)(x+1)/x−1.
If either limxf(x)=L or limxf(x)=L, then a function f(x) will have a horizontal asymptote of the form y=L.
Because "x" approaches to infinity and negative infinity, we must thus determine the limit value.
Take the formula f(x)=3x+7/2x5 as an example.
Now that "x" approaches to infinity, we must first determine the limit value.
In other words, [tex]\lim_{x\to \infty}f(x)[/tex]= [tex]\lim_{x\to \infty} \frac{3x+7}{2x-5}[/tex]
Using 'x' as the common denominator and numerator, we obtain
= [tex]\lim_{n \to \infty} \frac{x(3+\frac{7}{x} )}{x(2-\frac{5}{x} )}[/tex]
=[tex]\lim_{x \to \infty} \frac{(3+\frac{7}{x} )}{(2-\frac{5}{x} )}[/tex]
putting the cap on. As x → ∞, we will have 7/x → 0 and 5/x→0, giving us =3/2.
In other words, [tex]\lim_{x \to \infty} f(x)[/tex] = 3/2
Similarly, when "x" approaches toward negative infinity, calculate the limit value.
In other words,[tex]\lim_{x \to \infty} f(x)[/tex] = [tex]\lim_{n \to -\infty} \frac{3x+7}{2x-5}[/tex]
Applying the limit,
we get = [tex]\lim_{x \to -\infty} \frac{x(3+\frac{7}{x} )}{x(2-\frac{5}{x} )}[/tex]
=[tex]\lim_{x \to -\infty} \frac{(3+\frac{7}{x} )}{(2-\frac{5}{x} )}[/tex]
by taking the 'x' common to the numerator and denominator. As x, we will have 7/x→ 0 and 5/x→ 0; this gives us 3/2.
i.e., [tex]\lim_{x\to- \infty}f(x)[/tex] = 3/2
Therefore, the function has horizontal asymptote at y=3/2
There is just one horizontal asymptote for this function because the two limits were the same. Since asymptotes are lines, equations rather than merely numbers are used to describe them. There can only be two horizontal asymptotes in a function, one in each direction. When 'x' approaches any constant value 'c,' parallel to the y-axis, this is known as the vertical asymptote. The x-axis is parallel to flat lines known as horizontal asymptotes.

B 20%20%
C 200%200%
D 400%400%
E 30%30%
F 300%
a. The percent of Benny's mom's age to his age is 400%.
b. Benny's mom's age is 400% of his age.
What is a percent of numbers?
The percent of a number is its fraction that is expressed as percentage. Thus the percentage of a number or part of a number can be determined.
Considering the given question, the years of Benny and that of his mom were given as;
Benny's age = 12 years
His mom's age = 48 years
Thus we can deduce that;
a. The percent of his mom's age to that of Benny's = 48/ 12 * 100%
= 400%
b. Benny's mom's age is 400% of his age.
Therefore, the correct option to be selected is D.

The following ordered pairs represent the correct mapping.
(0,1), (2,7), (3,4), (-4,1), (-6,7)
What is Mapping?Mapping, any prescribed way of assigning to each object in one set a particular object in another (or the same) set. Mapping applies to any set: a collection of objects, such as all whole numbers, all the points on a line, or all those inside a circle.
From the diagram, we have both one-to-one and one-to-many mapping, so we first of all, list all of them.
one-to-one mapping ordered pairs include; (3,4)
one-to-many mapping ordered pairs include: (0,1), (2,7), (-4,1), (-6,7)
Therefore, the correct ordered pairs for the mapping will be both one-to-one and one-to-many mapping all put together, which is: (0,1), (2,7), (3,4), (-4,1), (-6,7)
