Answer:
a) y = 0, y = 4 and y = 5
b) y ⊂ (- ∞, 0) ∪ (0, 4) ∪ (5, ∞)
c) y ⊂ (4,5)
Step-by-step explanation:
Data provided in the question:
function y(t) satisfies the differential equation:
= y⁴ − 9y³ + 20y²
Now,
a) For constant solution
= 0
or
y⁴ − 9y³ + 20y² = 0
or
y² (y² - 9y + 20 ) = 0
or
y²(y² -4y - 5y + 20) = 0
or
y²( y(y - 4) -5(y - 4)) = 0
or
y²(y - 4)(y - 5) = 0
therefore, solutions are
y = 0, y = 4 and y = 5
b) for y increasing
> 0
or
y²(y - 4)(y - 5) > 0
or
y²
y ⊂ (- ∞, 0) ∪ (0, 4) ∪ (5, ∞)
c) for y decreasing
< 0
or
y²(y - 4)(y - 5) > 0
or
y²
y ⊂ (4,5)

I think.....
The number of small boxes that will fill the truck will be 144 boxes
The formula for calculating rectangular box is expressed as:
V = LWH
L is the length
W is the width
H is the height
For the large box
Volume = 12 * 18 * 16
Volume = 3,456 cubic inches
For the small box:
Volume of the small box = 3 * 2 * 4
Volume of the small box = 24 cubic inches
Number of small boxes that will fill the truck = 3456/24
Number of small boxes that will fill the truck = 144
Hence the number of small boxes that will fill the truck will be 144 boxes
