Answer:
B: A square
Step-by-step explanation:
Let's use the process of elimination:
We know that each shape here has opposite parallel sides so there's not much we can do about that one.
All sides congruent automatically gets rid of A.) Rectangle and C.) Parallelogram because they do not <em>always</em> have congruent sides
Opposite angles are congruent gets rid of D.) Rhombus. Although a rhombus can have all congruent angles, it isn't <em>always</em> congruent the way a square is. The definition of a rhombus is a quadrilateral with <em>equal side lengths</em>. Not angles.
So the only shape that meets each criteria all the time is a square.
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.
Answer:
The fraction 3/8 as a decimal is 0.375.
The fraction 3/8 as a percent is 37.5%
Well first you need to know how much it is. Then you can do this problem
