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:
can you send a picture?
Step-by-step explanation:
Input: 4, 6, 8
Output: 8, 10, 12
8-4 = 4
10-6 = 4
12 - 8 = 4
The rule is add 4 to the input.
The answer is A.
acknolegde requirements:
straight line.(horizontol or vertical? i dunno)
passes through 3,3
perpindicular to y=-x-4
perpidicular lines have negative recipricals
-1 ---- 1
y-3= 1(x-3)
y-3=x-3
cancel out
y=x
2.045 , 2.43 , 25/9. Hope this helped ;)
