PLEASE HELP! If 2580 people watched one show and 2920 people watched another show. How many people need to watch the third show
kolezko [41]

Answer:

3480

Step-by-step explanation:

Set it up so it looks like this.

(2580 + 2930 + x )/3 = 3000                Combine the terms on the left

(5510 + x) / 3 = 3000                              Multiply by 3

5510 + x = 9000                                    Subtract 5510

x = 9000 - 5510

x = 3490

Does that really work?

2580 + 2930 + 3490 = 9000

Which says it does work.

antiseptic1488 [7]

Answer:

c = 9 feet

Step-by-step explanation:

In this situation, one is to find the 'c' : that is, the distance between the vertex and the focus.

Given that, the equation for a vertical parabola:

y = (1/4c)(x-h)^2 + k

Supposing we place our parabola at the center, our equation becomes:

y = (1/4c)x^2

.

The problem gives us a point on the parabola: (12,4)

Then insert it in and solve for 'c':

y = (1/4c)x^2

4 = (1/4c)12^2

4 = (1/4c)144

4 = (1/c)36

4c = 36

c = 36/4

c = 9 feet
