Step-by-step explanation:
if 12 dollars for 6 bagels is true then each bagel is $2
if 9 dollars for 24 bagels then each bagel is $0.38
The slope of the line is (-6) and the y-intercept is 5
Answer:
Step-by-step explanation:
Remark
Assume all of the sheet of plywood is to be used.
Front and back = 2 * 2x *h
Top and Bottom = 2 * 2x * x
Left/Right side = 2 * x * h
Total area = 4xh + 4x^2 + 2xh
Total area = 6xh + 4x^2
Total area = 600
6xh + 4x^2 = 600
h = (600 - 4x^2)/6x
h = 100/x - 2/3 x
Volume = x * 2x * h
Volume = 2x^2 * (100/x - 2/3 x)
Volume = 200x - 4/3 x^3
I can do this without calculus (I think), but it is much easier to use it.
dV/dx = 200 - 4x^2
This is a maximum when dV/dx = 0
dV/dx = 200 - 4x^2 = 0
4x^2 = 200
x^2 = 50
x = 5√2
Replace x and y with the choices and see which one works:
A. 5 - 4(3) = 5 - 12 = -7, -7 is ≤ -6
The answer is A.
