Angle 2 is equal to angle 8. See the rest in the photo.
analytic geometry, also called coordinate geometry, mathematical subject in which algebraic symbolism and methods are used to represent and solve problems in geometry. The importance of analytic geometry is that it establishes a correspondence between geometric curves and algebraic equations.
Infinity to the 2 power duh
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.
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
