Answer: Choice A) There must be a vertical asymptote at x = c

Explanation:

The first limit \displaystyle \lim_{x\to c^{-}}h(x) = -\infty says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.

The limit \displaystyle \lim_{x\to c^{+}}h(x) = \infty means that as x approaches c from the right side, the y values head off to positive infinity.

Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.

Wayne and Garth are planning to have a concert. They have found two good options. Option 1: Malcolm's Music Hall will pay them $
storchak [24]

Answer:

50 people

Step-by-step explanation:

If you are to calculate the number of people that will come to the concert that will ensure option 1 and option 2 to yield equal amount

Let

x = number of people

Option 1:

Malcolm's Music Hall = 100 + 15x

Option 2:

Reggie's Reggae Room = 350 + 10x

Equate both options

100 + 15x = 350 + 10x

Collect like terms

100 - 350 = 10x - 15x

-250 = - 5x

x = -250/-5

x = 50 people

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! SUPER IMPORTANT QUESTION!!!
Anettt [7]

Answer:

Distance between two cities is 193.94 miles.

Step-by-step explanation:

We have,

Madison and Wisconsin have latitudes 43.0731°N and 45.9172°N respectively.

Thus, their difference is 45.9172°N - 43.0731°N = 2.8441°

We assumed, the diameter of earth is 7917.5 miles.

So, the radius = \frac{7917.5}{2} = 3958.75 miles

So, using the cosine formula, we have,

a^{2}=b^{2}+c^{2}-2bc\cos A

i.e. a^{2}=3958.75^{2}+3958.75^{2}-2\times 3958.75\times \cos 2.8441

i.e. a^{2}=31343403.13\times 0.0012

i.e. a^{2}=37612.08

i.e. a= 193.94 miles.

Hence, the distance between two cities is 193.94 miles.
