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:
108.3%
Step-by-step explanation:
The manufacturer spends $12,000 in buying the car parts and sells the car for $25,000
Selling price= $25,000
Cost price=$12,000
Gain= selling price-cost price
= 25000-12000
= $13000
The percentage profit can be calculated by applying the formular below
Profit= Gain/cost price×100/1
=13000/12000×100/1
=1.083×100
= 108.3%
Hence the percentage profit is 108.3%
Answer:
(0,0) is a solution to n=m and n=4m
Step-by-step explanation:
For the first equation, If u insert 0 as m into n=m
n=(0) then n will equal 0.
For the second equation, if u insert 0 as m in n=4m
n=4(0) then n will also equal 0.
So the answer is (0,0) is a solution to n=m and to n=4m
Hope this helps :)
