Step-by-step explanation:
if its not right than sorry
a. By the product rule,


b. By the same rule,


and


c. You might recognize the coefficients as those that appear in the expansion of
:
1, 1
1, 2, 1
1, 3, 3, 1
1, 4, 6, 4, 1
and so on; the general pattern (known as the general Leibniz rule) is

Answer:
G = (2, 9)
Step-by-step explanation:
The midpoint is the average of the endpoints, so we have ...
M = (G+H)/2
Solving for G gives ...
G = 2M -H = 2(5, 9) -(8, 9) = (10-8, 18-9)
G = (2, 9)
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 equation would be 3.75+t=11.2 so:
3.75+t=11.2
3.75+t-3.75=11.2-3.75
t=7.45, which is 7:35.
