Answer:
w = 36
Step-by-step explanation:
You can make a ratio 98 : 84 = 42 : w
49w = 1764
w = 36
You first do 432 divided by 9 which is 48. However, there could be multiple dimensions for the base because 48 is a composite number. One example could be 6 by 8

Answer:
a. 90 ft
Step-by-step explanation:
20+20+25+25
General equation of parabola: y-k = a(x-h)^2
Here the vertex is at (0,0), so we have y-0 = a(x-0)^2, or y = ax^2
All we have to do now is to find the value of the coefficient a.
(1,2) is on the curve. Therefore, 2 = a(1)^2, or 2 = a(1), or a = 2.
The equation of this parabola is y = 2x^2.
