Answer:
w≅8.46ft
Step-by-step explanation:
Data
focus=8
vertex=(0,0)
width=?
depth (y)=3ft
parabola equation: 
; then for V=(0,0), 
, be focus(f)=8in; 
→ 
we have that y=3ft then 
; but 1in≅0.083ft so 
→ x=±2.82, finally w=3*2.82≅8.46ft
Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = 
= 60
Answer:
the practice of analyzing and describing a complex phenomenon in terms of phenomena that are held to represent a simpler or more fundamental level, especially when this is said to provide a sufficient explanation.
Step-by-step explanation:
from dictionary . com or smth
Octagons have 8 sides. If each side is 5 feet then the perimeter is 40 feet. You add up the sides.
g(x) = x² - 5x + 2
You are looking for g(0). This means that you must replace all the x values in the equation above with 0
(0)² - 5(0) + 2
Now you need to solve according to the rules of PEMDAS:
(0)² - 5(0) + 2
0 - 5(0) + 2
0 - 0 + 2
0 + 2
2
g(0) = 2
