Quadratic formula since this trinomial is not factorable.
\frac{ - b +  -  \sqrt{ {b}^{2} - 4ac } }{2a}  \\  \frac{ - 1 +  -  \sqrt{ {(1)}^{2} - 4(1)( - 1) } }{2(1)}  \\  \frac{ - 1 +  -  \sqrt{1 + 5} }{2}  \\  \frac{ - 1 +  -  \sqrt{6} }{2}  \\ x =   \frac{ - 1 +  \sqrt{6} }{2}  \\ x =   \frac{ - 1 -  \sqrt{6} }{2}

Which equation represents the vertical asymptote of the graph?
Annette [7]

The curve is  y equals 0 from negative x to negative y near x equals negative 8.

If a curve has Vertical Asymptote i.e the line x=p,it is never touched by the given curve.The curve remains almost parallel to the line x=p, till the end.The two i.e a line and curve will never meet each other.

→ x is almost equal to p but not p.

so in the denominator , it is x=-8,

Vertical Asymptote occurs when we put , denominator of curve=0.

so vertical asymptote of curve is : x= -8

Sloan [31]

Answer:

The 10% condition would not apply here

Explanation:

The 10% condition is the recommended size of sample from the population to get a non biased result. The 10% condition requires that the sample be not more than 10% of the population.

Tossing a coin is an example of a Bernoulli trial. A Bernoulli trial is one that has two possible outcomes, this face of the coin or the other face of the coin. The 10% condition does not apply to Bernoulli trials that are independent events.

Therefore the 10% condition would not apply here because tossing a coin is an an independent event. An independent event is one with replacement.
