Suppose a cup of coffee is poured from a freshly-brewed pot and left to cool in a 75-degree room. Let the temperature (in °F) of the coffee be given by the function T(t) = 105(0.9634)^t + 75 where t is the time in minutes (t ≥ 0) the cup of coffee has been cooling after being poured. Use the equation T(t) = 100 to complete the following. a.) Use Newton’s method with an initial guess of t1 = 20 to estimate the solution to the equation, correct to six decimal places. (hint: Newton’s method only works for equations of the form f(x) = 0) b.) Interpret the solution from part (a) in context.

Question
Suppose a cup of coffee is poured from a freshly-brewed pot and left to cool in a 75-degree room. Let the temperature (in °F) of the coffee be given by the function
T(t) = 105(0.9634)^t + 75
where t is the time in minutes (t ≥ 0) the cup of coffee has been cooling after being poured.
Use the equation T(t) = 100 to complete the following.
a.) Use Newton’s method with an initial guess of t1 = 20 to estimate the solution to the equation, correct to six decimal places.
(hint: Newton’s method only works for equations of the form f(x) = 0)
b.) Interpret the solution from part (a) in context.
