Exponential function</h3>
An exponential function is in the form:

Where a is the initial value of y and b is the multiplier factor
Let y represent the amount of drug after x hours.
After 2 hours, there are 32 mg left. Hence:
After 5 hours, there are 10 mg left. Hence:
From equation 1 and 2, b = 0.6786, a = 69.5
The exponential function is given by 
At 1 hour:
y = 69.5(0.6786) = 47 mg

Answer:
The value of x = 24.4 units.
Step-by-step explanation:
Given
For a right-angled triangle with sides a and b, the hypotenuse c is defined as

substituting c = x, a = 14 and b = 20


units
Therefore, the value of x = 24.4 units.
