recall, slope = rise/run, and that a fraction is undefined when the denominator is 0, meaning this slope has a run = 0.

to make it short, when the slope is undefined, is a flag that we simply have a vertical line. Check the picture below.

Consider the function below. f(x) = 6x tan x, −π/2 < x < π/2 (a) find the vertical asymptote(s). (enter your answers as a

Molodets [167]

Answer: Does not exist.

Step-by-step explanation:

Since, given function, f(x) = 6x tan x, where −π/2 < x < π/2.

⇒ f(x) = $\frac{6x sin x}{cosx}$

And, for vertical asymptote, cosx= 0

⇒ x = π/2 + nπ where n is any integer.

But, for any n x is does not exist in the interval ( -π/2, π/2)

Therefore, vertical asymptote of f(x) where −π/2 < x < π/2 does not exist.

Find the slope of the line that passes through (10,8) and (1,9).

lesya [120]

Answer:

$-\frac{1}{9}$

Step-by-step explanation:

between (1, 9) and (10, 8), the x moves by 9 and y moves by -1

The slope is equal to: $\frac{\Delta y}{\Delta x} = \frac{-1}{9} = -\frac{1}{9}$

For Restaurant A, the owner wants to advertise a good cleanliness score to his customers. Which measure would make his score see

Semenov [28]

Answer:

median

Step-by-step explanation:

the median would make the score as good as possible, because there could be possible outliers. this really depends on if there are outliers or not. here is an example of what i need:

say you are trying to show your parents your grades:

here are your scores:

38, 88, 90, 91, 93, 95, 100

the median would be 91, which looks better.

the mean would be 85.

even though a majority of your grades are good, the one 38 makes the average go down. therefore, the median is a better advertiser.
