Answer:
a. Negative discriminant: above
b. Positive discriminant: below
c. Discriminant is zero: on
Step-by-step explanation:
If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis
If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis
If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis
Answer:
320 Customers took the survey
Step-by-step explanation:
As a result of the price increase, an additional $188.50 was made.
The first step here is to find out the increased revenue that was earned on each bag of popcorn:
<em>= New price - old price </em>
= 3.75 - 3.10
= $0.65
The concession stand sold 290 units so the increased amount that was earned was:
<em>= Incremental revenue x Number of units sold </em>
= 0.65 x 290
= $188.50
In conclusion, an additional $188.50 was made.

Answer:
2.1 months
Step-by-step explanation:
Let x represent the number of months
Set up expressions to represent the cost of each Internet provider
40x + 39 will represent the first one
30x + 60 will represent the other
Set these equal to each other and solve for x:
40x + 39 = 30x + 60
10x + 39 = 60
10x = 21
x = 2.1
So, the cost will be the same in 2.1 months
