Part C: Medicine Graph Analysis
Graph Analysis: The graph represents the function m, displaying the amount of medicine in the body, measured in milligrams, as a function of time (in hours).
- Estimated Value: To estimate m(0.5):
- Analyze the graph at the point corresponding to 0.5 hours.Time of Administration: Medicine is administered at noon. To estimate the amount at 4:30 PM:
- Calculate the elapsed time from noon to 4:30 PM, which is 4.5 hours.
- Use the graph to find m(4.5) by locating the corresponding point on the graph.Decrease Factor Calculation:
- First Hour: Calculate the factor by which the medicine amount decreased over the first hour (from 0 to 1 hour).
- Locate m(0) and m(1) on the graph.
- Compute the decrease factor as:
- First 1.5 Hours: Calculate the factor of decrease from 0 hours to 1.5 hours.
- Find m(1.5) on the graph.
- Compute the decrease factor as:
Part 13: Subscriber Growth Function
Function Representation: The equation represents the number of subscribers (in thousands) an influencer has after tracking for x months.
- Subscriber Metrics: The function suggests exponential growth based on time.True Statements Validation:
- Statement g: indicates how many months it will take for the influencer to reach 500,000 subscribers.
- Statement h: The graph suggests that the approximate value of is around 6.
- Statement i: accurately represents a logarithmic form related to the function f(x).
- Statement j: The influencer is projected to reach 100,000 subscribers shortly after 5 years (60 months).
- Statement k: Indicates that 5.4 is a reasonable approximation for based on the graph.
Part 14: Insect Population Growth Analysis
Graph Overview: A graph demonstrating insect population growth over several years, with key coordinates given.
- Coordinate Points:
- Point A: (1, 3)
- Point C: (4, 40)Growth Factor Calculation:
- Over 3 Years: Determine the increase factor from year 1 (3 insects) to year 4 (40 insects):
- Calculate by setting up:
- Annual Change: Calculate the rate of change over one year (average):
- Find the population at years 1 and 4, then divide the total increase over three years by 3 to find the approximate annual increase.
- Establish the annual change as follows:
Equation Creation:
- Growth Equation: Develop an equation for population growth per year, which could be modeled as exponential growth. A possible form might be:
- where:
- is the population at time t,
- is the initial population,
- is the growth rate,
- is time in years.
