Answer:
45/32 or 1.40
Step-by-step explanation:
Answer:
w = w L = 2w h = h
Volume: V = Lwh
10 = (2w)(w)(h)
10 = 2hw^2
h = 5/w^2
Cost: C(w) = 10(Lw) + 2[6(hw)] + 2[6(hL)])
= 10(2w^2) + 2(6(hw)) + 2(6(h)(2w)
= 20w^2 + 2[6w(5/w^2)] + 2[12w(5/w^2)]
= 20w^2 + 60/w + 120/w
= 20 w^2 + 180w^(-1)
C'(w) = 40w - 180w^(-2)
Critical numbers:
(40w^3 - 180)/w^2 = 0
40w^3 -180 = 0
40w^3 = 180
w^3 = 9/2
w = 1.65 m
L = 3.30 m
h = 1.84 m
Cost: C = 10(Lw) + 2[6(hw)] + 2[6(hL)])
= 10(3.30)(1.65) + 2[6(1.84)(1.65)] + 2[6(1.84)(3.30)])
= $165.75 cheapest cost

Answer:
not taking action
Step-by-step explanation:
because it is talking about how beautiful the gardens are and it could be said like this, "It makes the neighborhood more beautiful. There can be not taking action about that."
If his annual interest rate is 9%, his monthly interest rate should be 9% divided by 12 (number of months in a year)
9% is the same as 0.09
0.09 / 12 = 0.0075
The correct answer is 0.0075
