Answer:
A square has equal width and length. To find the area, you have to multiply the width by length but because they are the same length, you may some time see the formula written as L*L or .
The area of used up by the squares is 150sq feet. I found this by dividing 600 by 4. You can find an estimate by equating 150 the L*L. This gives you an approximate value of 12.
Answer:
The population is of 500 after 10.22 hours.
Step-by-step explanation:
The rate of change of the population of a certain organism is proportional to the population at time t, in hours.
This means that the population can be modeled by the following differential equation:
In which r is the growth rate.
Solving by separation of variables, then integrating both sides, we have that:
Applying the exponential to both sides:
In which K is the initial population.
At time t = 0 hours, the population is 300.
This means that K = 300. So
At time t = 24 hours, the population is 1000.
This means that P(24) = 1000. We use this to find the growth rate. So
So
At what time t is the population 500?
This is t for which P(t) = 500. So
The population is of 500 after 10.22 hours.
