  • In 1919, H. S. Reed and R. H. Holland published a paper on the growth of sunflowers. Included in the paper were the table and graph above, which show the height h, in centimeters, of a sunflower t days after the sunflower begins to grow. Over which of the following time periods is the average growth rate of the sunflower least?

    A
    Day 0 to Day 21
    B
    Day 21 to Day 42
    C
    Day 42 to Day 63
    D
    Day 63 to Day 84

  • In 1919, H. S. Reed and R. H. Holland published a paper on the growth of sunflowers. Included in the paper were the table and graph above, which show the height h, in centimeters, of a sunflower t days after the sunflower begins to grow. The growth rate of the sunflower from day 14 to day 35 is nearly constant. On this interval, which of the following equations best models the height h, in centimeters, of the sunflower t days after it begins to grow?

    A
    h = 2.1t − 15
    B
    h = 4.5t − 27
    C
    h = 6.8t − 12
    D
    h = 13.2t − 18

  • In 1919, H. S. Reed and R. H. Holland published a paper on the growth of sunflowers. Included in the paper were the table and graph above, which show the height h, in centimeters, of a sunflower t days after the sunflower begins to grow. The function h, defined by h(t) = at + b , where a and b are constants, models the height, in centimeters, of the sunflower after t days of growth during a time period in which the growth is approximately linear. What does a represent?

    A
    The predicted number of centimeters the sunflower grows each day during the period
    B
    The predicted height, in centimeters, of the sunflower at the beginning of the period
    C
    The predicted height, in centimeters, of the sunflower at the end of the period
    D
    The predicted total increase in the height of the sunflower, in centimeters, during the period
