Shilpa's gym membership includes a one-time fee of $20. She then pays a discounted fee of $5 for each visit. The function that s

hows her average cost after x visits is: Recall the general form of a rational function: Which statement defines the horizontal asymptote? m < n, so y = 0 is the horizontal asymptote. m = n, so y = am / bn is the horizontal asymptote. m = n, so y = 0 is the horizontal asymptote. m > n, so there is no horizontal asymptote.

Answer:

See explanation

Step-by-step explanation:

Given

$Flat = 20$

$Visit = 5$

Required

The function to represent x visits

This is calculated as:

$f(x) = Flat + Visit * x$

So, we have:

$f(x) = 20 + 5 * x$

$f(x) = 20 + 5x$

The second question is incomplete; however, I will explain how to calculate the horizontal asymptote of a rational function.

For polynomials with the same degree (i.e. m = n), the horizontal asymptote is calculated by dividing the coefficients of the highest degrees.

e.g.

$f(x) = \frac{6x^2 + 1}{3x^2 + 4}$ ---the degrees of both is 2

So, the horizontal asymptote is:

$y = 6/3$

$y =2$

If the numerator has a higher degree, then there is no horizontal asymptote.

If the denominator has a higher degree, then the horizontal asymptote is:

$y = 0$

Isabella had a week to read a book for a school assignment. She read an average of 36 pages per day for the first three days and

iogann1982 [59]

Ok, so what you want to do, is to start by adding the values together. So, she read an average of 36 pages for the first three days. So, you will multiply 36 by 3. Then, you will have 44 pages for the next three days, or 44 * 3. And finally, you have the last 10 pages. So, it is (36 * 3) + (44*3) + 10. So, 36 times 3 is 108, and 44 times 3 is 132. So, you now have 108 + 132 + 10. Add all of those values together, and your final answer is
250.

A rocket lifted off from a launch pad and traveled vertically 30 km, then traveled 40 km at 30 degrees from the vertical, and th

nika2105 [10]

Well, we are told that in the beginning, it has traveled 30km vertically, so do not forget to add that on at the end.

Next it says that it traveled 40km 30 degrees from vertical, so we set up a sin equation to solve for the missing side, n:

sin(angle)= opposite/hypotenuse:

sin(30) = n/40

40sin30=n

n=20km

Then it says at an angle of 45 degrees, it goes 100km. This means that we are given the hypotenuse of a right triangle, and we need to find the side that goes up and down. We shall call this length x.

We know that the angle opposite x is 45 degrees.

So, we will use sin to solve for x:

sin(angle)= opposite/hypotenuse

sin45= x/100

100sin45=x

x=70.711km

But remember, I said not to forget about that 30km from the very beginning? So we add up all of our vertical heights:

30km + 20km+ 70.711km = 120.711km

Answer:

$CV=\frac{0.1252}{1.57}=0.07975$

$CV=\frac{0.1317}{1.72}=0.07657$

The relative variability is almost equal in both samples a slight greater variability can be noticed in the first sample.

Step-by-step explanation:

The coefficient of variation of a sample is defined as the ratio between the mean standard deviation and the sample mean. And it represents the percentage relation of the variation of the data with respect to the average.

$CV=\frac{S}{\bar X}$

In the case of the first sample you have:

$CV=\frac{0.1252}{1.57}=0.07975$

In the case of the second sample you have:

$CV=\frac{0.1317}{1.72}=0.07657$

The relative variability is almost equal in both samples a slight greater variability can be noticed in the first sample.

Nick’s parents purchased their first home in the 1980’s with a 30-year mortgage at 19.5%.

<span>Interesting that there was no down payment..........The staggering monthly payment above would be enough to pay off the total mortgage in just over 5 years. Nick's parents would be much better off to save their money for a few years.</span>
