The approach model Problem set A Answers

Skills

  1. b = −12

    1. (a) b = −9
    2. (b) k = 5

  3. 3.72 km

  4. As t grows, k^(−t) tends to 0, so D tends to a. a = 10

In context

    1. (a) a = 6
    2. (b) b = −6
    3. (c) k = 2.5
    4. (d) 0.384 km
    5. (e) 4 hours

Stretch

    1. (a) k = 2.5
    2. (b) 3 hours
