It is true. Guptas did figure out the earth was round by observing lunar eclipses.
Answer: f(x) will have vertical asymptotes at x=-2 and x=2 and horizontal asymptote at y=3.
Step-by-step explanation:
Given function: 
The vertical asymptote occurs for those values of x which make function indeterminate or denominator 0.
i.e. 
Hence, f(x) will have vertical asymptotes at x=-2 and x=2.
To find the horizontal asymptote , we can see that the degree of numerator and denominator is same i.e. 2.
So, the graph will horizontal asymptote at 
i.e. 
Hence, f(x) will have horizontal asymptote at y=3.
Answer:
x = 30
Step-by-step explanation:
A triangle's angles add up to 180
Also, angles on a straight line add up to 180
180-100 = 80
80+70=150
180-150=30
Answer:
10 1/12
Step-by-step explanation:
In order to subtract fractions, you have to give them a common denominator.
18 1/2 can be rewritten as 18 6/12, as they are the same thing and 6/12 simplifies to 1/2. We make it 6/12 because we have to subtract it by 8 5/12, and the denominators are both 12.
So now we have 18 6/12 - 8 5/12, which gives us 10 1/12.
