step 1
Find the <span>average growth per year of the populations of rabbits farm A
</span><span>Over the first 2 years
for t=0
</span>numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=40
average=[40-5]/2---------> 17.5
step 2
Find the average growth per year of the populations of rabbits farm B
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=30
average=[30-5]/2---------> 12.5
step 3
<span>Compare the average growth per year of the populations of rabbits on both farms
farm A=17.5
farm B=12.5
</span><span>the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.
therefore
the answer is the option C)
</span>the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.
Answer:

Step-by-step explanation:
ASA postulate: 1 side, 2 angles equal
Answer:
The answer is can be a fraction that is not a whole number
Step-by-step explanation:
Ex. .5
1/2 that's rational number because it can be put into a fraction.
Hope this helps

Answer:
the initial population P₀ was 5938 people
Step-by-step explanation:
since the rate of increase of the population is proportional to the population itself, then the corresponding equation for a population P and time t is
dP/dt = k*P , where k= proportionality constant
dP/P = k*dt
∫dP/P =∫ k*dt
integrating between time t=0 (with P=P₀) and time t=t (with P=P)
ln (P/P₀)=k*t
if the population doubled , so P=2*P₀ at t=5 years then
ln (2*P₀/P₀)=k*5 years
k = ln 2 / 5 years
then the population is P=9000 for t= 3 years
ln (9000/P₀)=k*3 years
ln (9000/P₀)=ln 2 / 5 years *3 years
solving for P₀
P₀ = 9000 people * e^ (- ln 2 / 5 years *3 years ) = 9000 people *2 ^(-3 years / 5 years) = 5937.78 people ≈ 5938 people
therefore the initial population P₀ was 5938 people
Answer:
no solution.
Step-by-step explanation:
1) in order to explain, the given system should be resolved:
2) the both equations have the same slope (it is 3), it means the given lines are parallel, then no solution.
