Example 2. In a room, the temperature is given by T =
heater (in meters) and t is the elapsed time (in minutes) since the heat has been turned on. A person standing 3
meters from the heater 5 minutes after it has been turned on observes the following: (1) The temperature is
increasing by 1.2°C per minute, and (2) Walking away from the heater, the temperature decreases by 2°C per
meter as time is held constant. Estimate how much cooler or warmer it would be 2.5 meters from the heater after 6
f(x, t) degrees Celsius, where x is the distance from a
minutes.

- The unemployment rate U(t) varies with time. The table gives the percentage of unemployed in a certain country's labor force from 1999 to 2008. tU(t) tU(t) 1999 4.2 2004 5.3 2000 4.0 2005 5.1 2001 4.7 2006 4.5 2002 5.9 2003 6.4 2007 4.5 2008 5.9 (a) What is the meaning of U'(t)? O The derivative U'(t) is the percentage of people who are unemployed at a given time. The derivative U'(t) is the number of people who are unemployed at a given time. O The derivative U(t) is the rate at which the unemployment rate is changing with respect to time. O The derivative U'(t) is the rate at which people are being fired with respect to time. What are its units? O percent unemployed people per year O people O percent unemployed per year (b) Construct a table of values for U'(t). (Use h = 1 for 1999 and h = -1 for 2008.

From 1950 till 1988, the real price (i.e., the price adjusted for inflation) of chicken was not constant. As a result, the demand in that period also fluctuated. In the first graph below, the points show the observed real prices and the demands in the given time period. Many interesting relationships can be described well by a power law y = a 2. Denote by q the consumption per capita of chicken (in pounds) and by p the real price of chicken. One might wonder whether the demand function q(p) can be modelled by a function of the form q = ap for appropriate values of the constants a and b. a. Based on this first graph, could you easily decide that a power law is adequate? b. If you express a power law using logarithmic scales on both axes, what does the graph look like? Explain why this is so. What is the (geometric) meaning of the constants a and b? c. In the second graph below, we show the above data using logarithmic scales on both axes.

Each choice requires the same initial investment and each produces a continuous income stream of 6%, compounded continuously. The rate of flow of income from the furniture store is f(t)= 18,000, and the rate of flow of income from the book store is expected to be g(t) = 16,000e0.03t Compare the future values of these investments to determine which is the better choice over the next 8 years.

I don't see that part in development.Second. When there is variable "q" as (q+10)^2 on denominator , it can be replaced by q(t) from statement, since it asks for rate of change of I over t. So I see that something is missing in development, to then replace t = 12 workers. And I think is "dI/dt", no "dp/dt", where dI is Income partial derivatearrow_forward4.
