Answer:
Step-by-step explanation:
In a square, each angle is 90.
11x - 32 = 90
Add 32 to both sides
11x = 90 +32
11x = 122
x = 122/11
x = 
A.) P(t) = 130t - 0.4t^4 + 1200
The population is maximum when P'(t) = 0
P'(t) = 130 - 1.6t^3 = 0
1.6t^3 = 130
t^3 = 81.25
t = ∛81.25 = 4.3 months.
Maximum population P(t)max = 130(4.3) - 0.4(4.3)^4 + 1200 = 1,622
b.) The rabbit population will disappear when P(t) = 0
P(t) = 130t - 0.4t^4 + 1200 = 0
t ≈ 8.7 months
Answer:
x = -12
Step-by-step explanation:
-1/4x - 12 = x + 3
-x - 48 = 4x + 12
-x -4x = 12 + 48
-5x = 60
x = -12
Answer:
A. packaging costs
Step-by-step explanation:
Packaging costs woupd change based on how many products are being shipped. The other payments are fixed because they are the same amount paid regularly. Packaging would be considered a variable cost.
