Which description compares the vertical asymptotes of function A and function B correctly?
neonofarm [45]

Answer:

Option B:

Function A has a vertical asymptote at x = 1

Function B has a vertical asymptote at x = -3

Step-by-step explanation:

A function f(x) has a vertical asymptote if:

\lim_{x \to\\k^+}f(x) = \±\infty\\\\ \lim_{x \to\\k^-}f(x) = \±\infty

This means that if there is a value k for which f(x) has infinity or a -infinity then x = k is a vertical asymptote of f(x). Therefore, the closer x to k approaches, the closer the function becomes to infinity.

We can calculate the asymptote for function A.

\lim_{x \to \\1^+}(\frac{1}{x-1})\\\\ \lim_{x \to \\1^+}(\frac{1}{1^-1})\\\\ \lim_{x \to \\1^+}(\frac{1}{0}) = \infty\\\\and\\ \lim_{x \to \\1^-}(\frac{1}{x-1})\\\\\lim_{x \to \\1^-}(\frac{1}{0}) = -\infty

Then, function A has a vertical asymptote at x = 1.

The asymptote of function B can be easily observed in the graph. Note that the function b is not defined for x = -3 and when x is closest to -3, f(x) approaches infinity.

Therefore x = -3 is asintota of function B.

Therefore the correct answer is option B.

Two angels in a triangle add up two 115 degrees what is the size of the third angle
Bogdan [553]
The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle

solve
115+z=180
subtract 115 from boths ides
z=65

answer is third angle=65 degrees

Given the values of x and y find the exact (fraction) values of all six trig ratios
Anna35 [415]

Answer:

Step-by-step explanation:

Distance of (-3,4) to origin = √((-3)^2+4^2) = 5

sinθ = 4/5

cosθ = -3/5

tanθ = 4/(-3) = -4/3

cscθ = 1/sinθ = 5/4

secθ = 1/cosθ = -5/3

cotθ = 1/tanθ = -3/4
