Question

g(t) = -0.34 (t - 5.51)+ 8.26
The function g above models the growth rate of a certain plant, in millimeters per day (mm/day), in terms of the watering time t, in minutes per day (min/day). What is the meaning of (5.51, g(5.51)) in this context?

  1. The watering time of 5.51 min/day results in a plant growth rate of g(5.51)mm/day.
  2. The plant growth rate of 5.51 mm/day results in a watering time of g(5.51)min/day
  3. The watering time increases by g(5.51)min/day for every 5.51 mm/day increase in growth rate
  4. The growth rate increases by g(5.51)mm/day for every 5.51 min/day increase in watering time

The correct answer is: The watering time of 5.51 min/day results in a plant growth rate of g(5.51)mm/day.


    The given equation g(t) gives the growth rate in mm/day of a plant if watered for a time of t mins/day.
    Here t = 5.51
    So ,the watering time of 5.51 min/day results in a growth rate of g(5.51) mm/day.

    The world’s population has grown at an average rate of 1.9 percent per year since 1945. There were approximately 4 billion people in the world in 1975. Which of the following functions represents the world’s population P, in billions of people, t years since 1975 ? (1 billion = 1,000,000,000)

    We know the world's population one year after 1975 can be written as food into 1.01, nine to twelve years after 1975 can be written as '4' into 1.0 192, and so on. Similarly, suppose we continue to calculate three years after 1975. In that case, the world population will be 4.1.0 1923, and finally, we can conclude that the world population two years after 1975, as determined by the function P of t, will be equal to 4 into 1.0 19 t, and we can see that option one is the correct answer.
