Answer:
dP/dt = 650t = 650(2 ) = 1,300 people/year
The rate of increasing of population at the end of the year 1992 is 1,300 people/year
Step-by-step explanation:
Given;
Population function as;
P(t) =325 t^2 + 28547
The rate of change of the population dP/dt at any given time can be given as;
Rate = change in population/change in time = dP/dt
dP/dt = 2×325t = 650t
Therefore, after 1992;
t = 1992-1990 = 2years
dP/dt = 650t = 650(2 ) = 1,300 people/year
The rate of increasing of population at the end of the year 1992 is 1,300 people/year

Answer:
∠ABC = 84°
∠CAB = 54°
Step-by-step explanation:
Assume that a point on side AB, its point F
so that, EA = FA
Then triangle AEO ≅ triangle AFO
So,
OF = OE = BF
Triangle BOF is isosceles.
∠CEO=180−∠ABC
So that,
180 − 
∠ABC + 42 = 180
Now solve for ∠ABC.
∠ABC = 84°
∠CAB = 180 - 84 - 42 = 54°
That's the final answer.
