Birth amd death rates of animal populations are typically not constant, they vary periodically with the passage of the season. Find P(t) if P satisfies the differential equation

dP/dt=(2+9cos(2pit))P

where t is in years and there is an intial population C

P(t)=?

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

the weight of the object inside the box!

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
