Let the length of the rectangle be x units then the width = (210 - 2x) / 2
= 105 - x units
Area A = x(105 - x) = 105x - x^2
Finding the derivative:_
dA/dx = 105 - 2x = 0 for max/minm volume
x = 52.5
this is for a maximum area because second derivative is negative ( = -2).
width = 105 - 52.5 = 52.5
Dimension for maximum area = 52 1/2 * 52 1/2. ( The rectangle is actually a square).
A=Pe^rt
A: Amount
P: Principle
r: Rate (4.25%; .0425)
t: Time in years
A= 500e^(.0425*t)
Well for 1 pitcher of lemonade she needs atleast 2 cups, so if she were to make 3 pitchers that would be 2 cups for each pitcher. Solution is to just multiply 2cups to the number of pitchers:
2cups x 3 pitchers = 6 cups
Melanie would need 6 cups of sugar if she were to make 3 pitchers of lemonade. :))
