Hi! Your answer is 13.
All you have to do is divide 52 by 4. When you do this, you will find how many laps they walked per hour.
(They walked 52 laps in 4 hours)
52 / 4 = 13
They walked 13 laps in one hour.
Hope this helped!
Answer:
The answer is x > -1
Step-by-step explanation:
This is because if it were a closed circle, it would have to the include the inequality -1 but since it is an opened circle, that inequality is not included. So in conclusion, Any number could be used to represent x as long as it is a greater number than -1. I hope this makes sense.
Answer:

Step-by-step explanation:
The logistic differential equation is as follows:

In this problem, we have that:
, which is the carring capacity of the population, that is, the maximum number of people allowed on the beach.
At 10 A.M., the number of people on the beach is 200 and is increasing at the rate of 400 per hour.
This means that
when
. With this, we can find r, that is, the growth rate,
So




So the differential equation is:


The answer is 158.8333333333333
