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= ????
Answers
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.

Find the measures of an interior angle and an exterior angle of a regular polygon with 6 sides.
Answers
To find the measure of one angle, the formula is 360/n where n is the number of the sides of the polygon.
360/6 = 60°
The sum of all internal angles of a polygon can be find with the formula (n-2)*180° where n is the number of the sides. In this case 180(6-2) = 180*4 = 720°
To find one internal angle, follow this formula [180(n-2)] / n = [720/6] = 120°
Anyway, you can pick a vertex and from that vertex start to draw diagonals.
There will be some triangles, the sum of all internal angles of a triangle is 180°. In a polygon, the sum of all internal angles equals to the sum of all internal angles of all the triangles.
Hope I'm clear.
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°.

Which shows the graph of the solution set of 3y – 2x > –18? Mark this and return
Answers
First, you disregard the inequality to graph the equation. Find the x- and y-intercepts, plot them, and connect these two dots by extending infinitely from both sides.
x-intercept: let y = 0
0 - 2x = -18
x = 9
y-intercept: let x = 0
3y- 0 = -18
y = -6.
The graph is shown in the picture. Next, you test the inequality by choosing a random data point that does not coincide with any of the data points passed by the line. Suppose, we choose the origin (0,0)
3y- 2x > -18
3(0) - 2(0) > -18
0 > 18
The inequality is true for (0,0), Thus, the shaded region must include this point. All of the region to the left bounded by the line is a solution. Note that the data points are hollow because they are not part of the solution because of the inequality '>'. If it were ≥, then those points would be solid.

B. is inconsistent
C. is dependent
D. is consistent
Answers
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 median of the following set of data. $12.50, $13.23, $11.20, $14.50, $12.50, $13.23, $15.60, $15.75
Answers
It's 13.23
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

Answer is A
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.
The common ratio,r, is -16/8=32/-16=-64/32=-2, and the first term, a, is 8
So the rule for this sequence is:
a(n)=8(-2)^(n-1), so the 13th term is:
a(13)=8(-2^12)
a(13)=32768

Quadrilateral ABCD is an Isosceles Trapezoid. Which angle is congruent to Angle C?
Answers
The base angles C and D are congruent because this is an isosceles trapezoid. In addition, angle A = angle B because this is another pair of base angles (imagine rotating the figure 180 degrees to make segment AB the base)
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.

If Grant walks from his house to Isobel's house, then on to Hannah's house along the path shown, how far will he have walked in blocks? Round your answer to the nearest tenth.
Answers
5^2 + 7^2 = c^2
25 + 49 = c^2

so grant's to Isabelle's is 8.6 blocks, then from there to hannah's house, which is 7 blocks....so he walks a total of 8.6 + 7 = 15.6 blocks
The total distance covered in the graph from Grant to Isobel's house and Isobel's house to Hannah's house is 15.06.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
As per the given coordinate has been drawn in the graph below,
The locus of the path from Grant's house to Isobel's house and then Hannah's house is making a right-angle triangle.
By Pythagoras' theorem,
Distance from Grant's house to Isobel's house ⇒
√(4² + 7²) = 8.06
The distance from Isobel's house to Hannah's house ⇒ 3 + | -4| = 7
Therefore, 8.06 + 7 = 15.06.
Hence "The total distance covered in the graph from Grant to Isobel's house and Isobel's house to Hannah's house is 15.06".
