Question

C equals 5 over 9 left parenthesis R minus 491.67 right parenthesis
The equation above expresses the temperature C,
in degrees Celsius, in terms of the temperature R,
in degrees Rankine. Which of the following expresses the temperature in degrees Rankine in
terms of the temperature in degrees Celsius?

  1. R equals 9 over 5 C plus 491.67
  2. R equals 9 over 5 C minus 491.67
  3. R equals 5 over 9 C plus 491.67
  4. R equals 5 over 9 C minus 491.67

The correct answer is: R equals 9 over 5 C plus 491.67


    C equals 5 over 9 left parenthesis R minus 491.67 right parenthesis C equals 5 over 9 left parenthesis R minus 491.67 right parenthesis not stretchy rightwards double arrow 9 over 5 C equals R minus 491.67 not stretchy rightwards double arrow9 over 5 C plus 491.67 equals R
    R equals 9 over 5 C plus 491.67

    There were no jackrabbits in Australia before 1788 when 24 jackrabbits were introduced. By 1920, the population of jackrabbits had reached 10 billion. If the population had grown exponentially, this would correspond to a 16.2% increase, on average, in population each year. Which of the following functions best models the population p(t) of jackrabbits t years after 1788?
