Answer:
21.25 m
Step-by-step explanation:
y = Ax² + Bx + C
Set the origin at the middle of the span so that the point (0, 0) is on the curve
0 = A(0)² + B(0) + C means C = 0
The points (200, 85) and (-200, 85) are on the curve
85 = A(200)² + B(200)
85 = A(-200)² + B(-200)
85 - 40000A - B(200) = 85 - 40000A + B(200)
- B(200) = B(200)
-400B = 0
B = 0
85 = A(200)²
A = 85/40000
y = 85x²/40000
y = 85(100)²/40000 = 21.25 m
Answer:
The number is 70
Step-by-step explanation:
Is means equals and of means multiply
91 = 130% *W
Changing to a decimal form
91 = 1.3W
Divide each side by 1.3
91/1.3 = 1.3 W/1.3
70 = W
Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as 
then the equation relating them is
c = k ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×
= 8k ( divide both sides by 8 )
1.75 = k
c = 1.75 ← equation of variation
When d = 324 , then
c = 1.75 × 
= 1.75 × 18 = 31.5
Divide 9 by 15.
9/15= 0.6
