Question

A machine in a laboratory is set to steadily increase the temperature inside. The temperature in degrees Celsius inside the machine after being turned on is a function of time, in seconds, given by the equation f(t)=22+1.3t

1. What does f(3) mean in this situation?
2. Find the value of f(3) and interpret the value.
3. What does the equation f(t)=35 mean in this situation?
4. Solve the equation to find the value of t for the question.

    Step-by-step explanation:

    Step 1:  Answer the first question

    f(3) means the temperature after 3 seconds

    Step 2:  Answer the second question

    The value of f(3) = 22 + 1.3(3) → 25.9 degrees

    The value of f(3) which is 25.9 means that after 3 seconds, the temperature is 25.9 degrees.

    Step 3:  Answer the third question

    f(t) = 35 means that after a t amount of seconds, the temperature is 35 degrees.

    Step 4:  Answer the fourth question

    f(t) = 35  so… 35 = 22 + 1.3t

    35 - 22 = 22 - 22 + 1.3t

    13 = 1.3t

    13 / 1.3 = 1.3t / 1.3

    10 = t

    10 seconds

    Answer:

    1) f(3) means the temperature after 3 seconds

    2) f(3) = 22 + 1.3(3) = 25.9

    Temperature after 3 seconds is 25.9°C

    3) f(t) = 35 means after t seconds, temperature was 35°C

    4) 35 = 22 + 1.3t

    1.3t = 13

    t = 10 seconds
