Given :
The percent of concentration of a certain drug in the bloodstream x hours after the drug is administered is given by
.
To Find :
Find the time at which the concentration is a maximum. b. Find the maximum concentration.
Solution :
For maximum value of x, K'(x) = 0.

Since, time cannot be negative, so ignoring x = -3 .
Putting value of x = 3, we get, K(3) = 15/( 9 + 9) = 5/6
Therefore, maximum value drug in bloodstream is 5/6 at time x = 3 units.
Hence, this is the required solution.
The nearest integer is zero.
Answer:
Step-by-step explanation:
Temperature is a function of the time of day. There can be only one temperature at any particular time.
In contrast, a particular temperature can occur more than one time in a day, so time is not a function of temperature.
Answer:
6 over 50
Step-by-step explanation:
There are 6 purple draws out of 50 total, so the probability is 6/50
Answer:
5
Step-by-step explanation:
the slope is the change in y divided by the change in x
as y goes up 5 x goes up 1
5/1=5 so the slope is 5
