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:
y = 7x + 15
Step-by-step explanation:
The y-value when x=0 is the y-intercept: b=15.
The difference between the y-value at x=1 and that y-intercept is the slope: m=22-15=7.
Using these in the formula for the line, we have ...
y = 7x + 15
Answer:
These two lines that are running horizontally are parallel lines.
The angle with measure 115 degrees is congruent to angle 2 (by the law of parallel lines).
So, if these two angles are congruent, angle 2 is also 115 degrees.
