Answer: 4 feet
Step-by-step explanation:
An airplane is 180 feet long.
Blake makes a scale model of the airplane which is 1:45 of its actual size. To find the length of the airplane model goes thus:
= 1/45 × 180
= 4 feet
The model is 4 feet
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
