Answer:
Step-by-step explanation:
Since this is a right triangle, we will use a right triangle trig identity to solve our problem. The side opposite the reference angle A is given as 5, and the side adjacent to the reference angle is given as 7. The trig ratio that uses the sides opposite and adjacent is the tangent ratio:
Hit the 2nd button on your calculator then the tan button which displays:
Enter 5/7 after that open parenthesis and hit = to get that
A = 35.54°

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.
I believe that the equations answer is around 1170. The answer to the equation is 1172
The answer is (x, y) = (-1, 4) hope this helped
