Question

A cup of coffee at 90 Celsius is put into a 20 Celsius room, t=0. The coffee's temperature is changing at a rate of r (t) = -7(0.7^t) Celsius per minute, with t in minutes. Estimate the coffees temperature when t=10.

Round answer to TWO decimal places:

Answer #1

Suppose a cup of coffee is at 100 degrees Celsius at time t=0,
it is at 70 degrees at t=15 minutes, and it is at 45 degrees at
t=30 minutes. Compute the ambient temperature.

A cup of tea is cooling in a room that has a constant
temperature of 70 degrees Fahrenheit (F). If the initial
temperature of the tea, at time t=0 minutes, is 200 F and the
temperature of the tea changes at the rate: R(t) -6.89e^(-.053t)
degrees Fahrenheit per minute, what is the temperature, to the
nearest degree, of the tea after 4 minutes? 2. On the closed
interval [2, 4], which of the following could be the graph of a...

(1 point) Newton's Law of Cooling states that the rate of
cooling of an object is proportional to the temperature difference
between the object and its surroundings. Suppose t is time, T is
the temperature of the object, and Ts is the surrounding
temperature. The following differential equation describes Newton's
Law dT/dt=k(T−Ts), where k is a constant. Suppose that we consider
a 95∘C cup of coffee in a 25∘C room. Suppose it is known that the
coffee cools at a...

When a small ice cube at -10∘C is put into a cup of water at
room temperature, which of the following plays a greater role in
cooling the liquid water: the warming of the ice from -10∘C to 0∘C
, or the melting of the ice?
a) the warming of the ice from -10 ∘C to 0 .C
b) the melting of the ice

Your 300 mL cup of coffee is too hot to drink when served at
90°C. An ice cube, taken from a −20°C freezer is used to cool your
coffee to a pleasant 60°C. Assume that you have a well-insulated
cup.
a. Provide the statement of energy conservation for this closed
“coffee-ice” system.
b. What is the heat lost by coffee in bringing down the
temperature to 60°C?
c. How much heat is consumed in converting ice to water at 0°C?...

Problem 7-19 (Algo) A cafeteria serving line has a coffee urn
from which customers serve themselves. Arrivals at the urn follow a
Poisson distribution at the rate of 2.5 per minute. In serving
themselves, customers take about 16 seconds, exponentially
distributed.
a. How many customers would you expect to see, on average, at
the coffee urn? (Do not round intermediate calculations. Round your
answer to 2 decimal places.)
b. How long would you expect it to take to get a...

13. Podunk City has two
coffee shops and everyone in the city buys one cup of coffee per
day. The owners of these shops can serve Maxwell
House Coffee or they can serve
Le Fru
FruGourmet Coffee (simplifying
assumption—suppose they
charge
the same price for either cup of coffee). Assume that customers
strictly prefer Le Fru
Fru coffee so that if one firm
offers Le Fru
Fru and the other doesn’t,

1) When interest is compounded continuously, the amount of money
increases at a rate proportional to the amount S present
at time t, that is,
dS/dt =
rS, where r is the annual rate of
interest.

$4000 is deposited in a savings account drawing 5 1/4 $ % annual
interest compounded continuously. (Round your answer to the nearest
cent.)
