Answer:
c. dP/dt = (1/5)P
Step-by-step explanation:
Given that the rate of change of population with respect to time dP/dt is directly proportional to the population, P, we have
dP/dt ∝ P
dP/dt = kP
Given that dP/dt = 2 million insects per day and P = 10 million insects after 5 days, So,
2 = k × 10
k = 2/10
k = 1/5
So, dP/dt = kP
dP/dt = (1/5)P
Step-by-step explanation:
Area1=4×3=12cm²
Area2=6×3=18cm²
Area3=(6+3)×(12+4)=9×16=144cm²
Total area = area1 + area2 + area3
Total area= 12+ 18+144=174cm²
