The total cost of a vacation to a rain forest includes a fee of $560 for the tour guide, plus $630 per person. The function y=560+630x/ x
models the average cost per person, in dollars, when x people go on the vacation.
What is the horizontal asymptote of the function?
y= ????
Answer: y= 630 is the horizontal asymptote for the given function.
Step-by-step explanation:
Horizontal asymptotes are horizontal lines that the graph of the function approaches as x tends to [tex]+\infty[/tex] or [tex]-\infty[/tex].
Thus, If there is a function f(x),
Then Its horizontal asymptote, y = [tex]\lim_{x\rightarrow \infty} f(x)[/tex]
Here the given function is, [tex]f(x) = \frac{560+630x}{x}[/tex]
Thus its horizontal asysmptote is, y = [tex]\lim_{x\rightarrow \infty} \frac{560+630x}{x}[/tex]
⇒ y = [tex]\lim_{x\rightarrow \infty}560/x+630[/tex]
⇒ y = 0+ 630
⇒ y= 630 is the horizontal asymptote of the given function f(x).
The horizontal asymptote of y = (630x + 560)/x is y = 630.
Linear functionA linear function is given by:
y = mx + b
where y, x are variables, m is the rate of change and b is the y intercept.
Given the total cost as y = 630x + 560.
For the function y = (630x + 560)/x, the horizontal asymptote is at:
y = 630x/ x = 630
The horizontal asymptote of y = (630x + 560)/x is y = 630.

Quadrilateral ABCD is an Isosceles Trapezoid. Which angle is congruent to Angle C?
Answer:
The reason why any angles coming out from D and C are congruents is because of the geometry coungruence's concept of 2 items having the same pattern, shape or form and size as the mirror image of the other.
2 angles would be congruent by being the same angle in degrees or radians.
Thereby any angle coming out from C as vertex would be congruent with any other vertex point angle mirroring the resulting figure shaped by the radiants or degrees of such angle.

A small class has 10 students, 5 of whom are girls and 5 of whom are boys. The teacher is going to choose two of the students at random. What is the probability that the first student chosen will be a girl and the second will be a boy? Write your answer as a fraction in simplest form.
Answer:
The required probability is 5/18.
Step-by-step explanation:
Total number of total students = 10
Number of girls = 5
Number of boys = 5
Formula for probability:
[tex]Probability=\frac{\text{Favorable outcome}}{\text{Total outcome}}[/tex]
The probability that the first student chosen will be a girl = [tex]\frac{5}{10}=\frac{1}{2}[/tex]
After selecting 1 student, the total number of student is
[tex]10-1=9[/tex]
The probability that the second student chosen will be a boy = [tex]\frac{5}{9}[/tex]
The probability that the first student chosen will be a girl and the second will be a boy is
[tex]P=\frac{1}{2}\times \frac{5}{9}[/tex]
[tex]P=\frac{5}{18}[/tex]
Therefore the required probability is 5/18.

Find the median of the following set of data. $12.50, $13.23, $11.20, $14.50, $12.50, $13.23, $15.60, $15.75
Answer:
The answer is 13.23
Step-by-step explanation:
In order to determine the median of the set of data, we have to know about median and how applicate it.
The median of a set of data is the middlemost number in the set. The median is also the number that is halfway into the set. To find the median, the data should first be arranged in order from least to greatest.
Also, if there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
So, we arrange the set of data:
11.20
12.50
12.50
13.23
13.23
14.50
15.60
15.75
The data set is an even number.
The two middlemost numbers are: 13.23; 13.23.
So, the mean (average) is:
(13.23+13.23)/2=13.23
Finally, the median of the set of data is 13.23

When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither numerator determinant is zero, then the system _______.
A. has infinite solutions
B. is inconsistent
C. is dependent
D. is consistent
If the determinant of the coefficient matrix is zero and neither numerator determinant is zero when using Cramer's Rule to solve a system of equations, then the system is inconsistent, meaning there's no solution.
Explanation:When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither numerator determinant is zero, then the system is inconsistent.
Cramer's Rule is a method applied in linear algebra to solve a system of linear equations. The rule states that the system is inconsistent if the determinant of the coefficient matrix is zero (meaning the equations do not intersect) but at least one of the numerator determinants are nonzero. This condition indicates that there's no solution to the system of equations.
On the contrary, if the determinant of the coefficient matrix is zero an all the numerator determinants are also zero, the system is said to be dependent, meaning it would have infinitely many solutions.

Find the measures of an interior angle and an exterior angle of a regular polygon with 6 sides.
The interior angle of a regular hexagon is 120 degrees, and the exterior angle is 60 degrees.
Explanation:To find the measures of an interior angle and an exterior angle of a regular polygon with 6 sides, we will use the fact that the sum of interior angles of a polygon is given by (n-2)×180°, where 'n' is the number of sides of the polygon. Thus, a regular hexagon will have its interior angles sum to (6-2)×180° = 720°. Since all interior angles in a regular polygon are equal, each interior angle will be 720° ÷ 6 = 120°. The exterior angle of a regular polygon is calculated as 360° ÷ n. Therefore, an exterior angle of a regular hexagon will be 360° ÷ 6 = 60°.
So, the interior angle of a regular hexagon is 120°, and the exterior angle is 60°.

Person 1 can do a certain job in twenty-one minutes, and person 2 can do the same job in twenty-eight minutes. When completing the job together, which expression would be used to represent the amount of work done by person 1?
21
1/21
x/21
21x
Answer:
[tex]\frac{1}{21}[/tex] would be used to represent the amount of work done by person 1.
Step-by-step explanation:
When someone does a work in x time,
Then, the work done by the person in one day = [tex]\frac{1}{x}[/tex]
Given,
Time taken by person 1 = 21 minutes
Thus, by the above statement,
The one day work of person 1 = [tex]\frac{1}{21}[/tex]
Hence, [tex]\frac{1}{21}[/tex] would be used to represent the amount of work done by person 1.
Second option is correct.
