The discriminant is b^2 -4ac
a = 1
b = -2
c = 4
discriminant = 4 -4 * 1 * 4 =
4 -16 =
-12
I get MINUS 12 as the answer but that isn't one of the choices.

<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

5 numbers are selected from a set of 70, along with one number from a set of 25, hence the number of combinations is given by:

Only one combination is correct, hence the probability of winning is given by:
A. 1/302575350.

Answer:
C =28.26m
Step-by-step explanation:
We are walking around a circle, which means we are finding the perimeter. The perimeter of a circle is called the circumference.
We find the circumference by
C = pi *d where d is the diameter
C = 3.14 * 9
C =28.26m
