I cannot figure out how to find the numerical values of a and b. I’ve gotten a=125/(b+10) and b=125a-10, but I need to find the exact values of a and b.
Transcribed Image Text:3. Elphaba the squirrel, the notorious criminal, is planning a prison escape. To aid her in her
escape, her friend Walt has concocted a supplement that will make her stronger and more agile.
The concentration 7(t) of the supplement in Elphaba's system, in mg/ml, t minutes after it is
administered is given by the formula
T(t) =
where a and b are constants.
Sat³
b(t-6)² + 10
for 0 ≤t≤5
for 5 <t≤7
a. Given that T(t) is DIFFERENTIABLE, find a and b. Give your answers in EXACT FORM,
i.e., a FRACTION. You do not need to use the limit definition to compute derivatives in
this problem or any problem from now on unless said so explicitly in the instructions.
(Hint: Remember that for a function to be differentiable, it needs to also be
CONTINUOUS.)
b. Using (either of) the values for a and b you found in part a, find the EQUATION FOR THE
TANGENT LINE to the graph of y = T(t) at t = 5. Write the terms in the equation in EXACT
FORM, i.e., with FRACTIONS.
c. Find the INSTANTANEOUS RATE OF CHANGE of the concentration of the supplement in
Elphaba's system at t = 2. Include units.
