According to simple physiological model an athletic adult male needs 20 calories per day per pound of body weight to maintain his weight.if he consume a more or fewer calories than those required to maintain his weight changes at a rate proportional to difference between the number of calories consumed and the number of calories consumed and the number needed to maintain his current weight the constant of proportionality is 1/3500 pound per calorie .suppose that a particular person has a constant caloric intake of H .let W(t) be the person's weight in pounds at time t.(a) what is the differential equation has the solution W(t)? (b)solve this differential equation if the person starts out weighing 155 pounds and consumes 2600 calories a day
Please don't provide handwritten solution..... A model for the spread of an epidemic is that the rate of new infections is proportional to the product of the number of infected people with the number of uninfected people. In a town of 10000 total inhabitants, 100 have the disease at the beginning of the week and 1200 have the disease at the end of the week. According to this model, how long does it take for 90% of the town to become infected?
Temperature between fluids in a heat exchanger used to heat a medium Based on the difference (X) (X> 2) the annual fuel cost (Y1) and the annual investment cost (Y2) are given as. Determine the temperature difference that will minimize the annual total cost (Y) Y1 = 6X2 - 10X + 5000 Y2 = 25000 - X2 - 140X
The variable cost for the production of a calculator is $14.65 and the initial investment is $110,000. (a)Find the total cost C as a function of x, the number of units produced. (b)Use differentials to approximate the change in the cost for a one-unit increase in production when x = 50,000. (Round your answer to two decimal places.)
The air in a room with volume 100 cubic meters initially contains .2% carbon dioxide.Fresher air containing .1% carbon dioxide flows into the room at a rate of 1 cubic meter perminute and the mixed air flows out at the same rate. Find the percentage of carbon dioxidein the air as a function of time.
A model for the spread of an epidemic is that the rate of spread is proportional the number of people infected and the number of people not infected.

The demand function for the Viking Boat’s 34-ft Sundancer yacht isp = 200 − 0.01x ln x,where x denotes the number of yachts and p is the price per yacht in hundreds of dollars.(a) Find the revenue function and the marginal revenue function for this model of yacht.(b) Use the result of part (a) to estimate the revenue realized from the sale of the 500-th34-ft Sundance yacht. (Note: This is an estimate, so be careful to use the correct functionfrom part (a) and to evaluate it at the correct value of x.)(c) Now compute the exact revenue realized from the sale of the 500-th 34-ft Sundance yacht. (d) Comment on the approximation provided in part (b).
