Answer:
y = -0.005x² + 50
Step-by-step explanation:
The diameter is 200 feet, so the parabola has roots at (-100, 0) and (100, 0). The maximum height is 50, so the vertex of the parabola is at (0, 50).
Using vertex form of a parabola:
y = a (x − h)² + k
y = a (x − 0)² + 50
y = ax² + 50
Plugging in either root:
0 = a (100)² + 50
a = -0.005
y = -0.005x² + 50

Step-by-step explanation:
Answer:
-13 = n - 4
Step-by-step explanation:
-13 is four less than a number n
so four less than n can be written as n - 4
-13 = n - 4
n= -9
Answer:
4/pi=w-6/pi
<u>4</u><u> </u><u> </u><u> </u>=<u> </u><u>w</u><u>-</u><u>6</u>
<u>Pi</u><u> </u><u> </u><u> </u><u> </u><u> </u><u>pi</u>
Cross mutiply
Pi(w-6)=4(pi)
Wpi - 6pi =4pi
Collect like terms
Wpi=4pi + 6pi
Wpi =10pi
<u>Divide</u><u> </u><u>both</u><u> </u><u>sides</u><u> </u><u>by</u><u> </u><u>pi</u>

Pi pi
W = 10
