Answer:
Each inhalation has 750 micrograms of metaproterenol sulfate.
Step-by-step explanation:
First step: How many miligrams are there in each inhalation.This can be solved by a rule of three problem.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
In this step, our measures are:
- The number of inhalations.
- The quantity inhaled.
As the number of inhalations increases, so does the quantity inhaled. This means that this is a direct rule of problem.
300 inhalations contains 225mg of metaproterenol sulfate. How many miligrams are in a inhalation?
300 inhalations - 225mg
1 inhalation - xmg
300x = 225
x = 0.75mg
Each inhalation has 0.75mg of metaproterenol sulfate.
Final step: Conversion of 0.75mg to micrograms.
Each mg has 1000 micrograms. So:
1mg - 1000 micrograms
0.75mg - x micrograms
x = 1000*0.75
x = 750 micrograms
Each inhalation has 750 micrograms of metaproterenol sulfate.
The average rate of change of a graph between two intervals is given by the difference in value of the values on the graph of the two interval divided by the difference between the two intervals.
Part A.
From the graph the average Valentine's day spending in 2005 is 98 while the average Valentine's day spending in 2007 is 120.

Answer:
The correct option is B.
Step-by-step explanation:
A function is called an exponential function if it has common ratio.
A function is called an linear function if it has common difference.
In option A.
Since the given table has different ratio, therefore it is not an exponential function. Option A is incorrect.
In option B.
Since the given table has common ratio, therefore it is an exponential function. Option B is correct.
In option C.
Since the given table has different ratio, therefore it is not an exponential function. Option C is incorrect.
In option D.
Since the given table has different ratio, therefore it is not an exponential function. Option D is incorrect.
