How do You See it? An electronically controlled thermostat in a home is programmed to lower the temperature automatically during the night. The temperature in the house T (in degrees Fahrenheit) is given in terms of t, the time in hours on a 24-hour clock (see figure).
(a) Explain why T is a function of t.
(b) Approximate T(4) and T(15).
(c) The thermostat is reprogrammed to produce a temperature H for which
How does this change the temperature?
(d) The thermostat is reprogrammed to produce a temperature H for which
How does this change the temperature?

- Repeat the previous exercise to find the formula forthe APY of an account that compounds daily. Usethe results from this and the previous exercise todevelop a function I(n)for the APY of any accountthat compounds n times per year.arrow_forwardUse your schools library, the Internet, or some other reference source to find real-life applications of approximations of functions.arrow_forwardThe half-life of plutonium-244 is 80,000,000 years. Find function gives the amount of carbon-14 remaining as a function of time, measured in years.arrow_forward
- Earthquake the graph shows the vertical acceleration of the Ground from the 1994 Northridge earthquake in Los Angles, as measured by a seismograph. (Here t represents the time in seconds.) (a) At what time t did the earthquake first make noticeable movement of the Earth? (b) At what time t did the earthquakes seem to end? (c) At what time t was the maximum intensity of the earthquake list reachedarrow_forwardA forest fire leaves behind an area of grass burned in an expanding circular pattern. If the radius of the circle of burning grass is increasing with time according to the formula r(t)=2t+1 , express the area burned as a function of time, t (minutes).arrow_forwardIf you travel 300 miles on the first day and then drive v miles per hour for t hours on the second day, then the total distance traveled over the teo-day period is given by d=300+vt miles. Use a formula to express v as a function of d and t for this two-day event.arrow_forward
- In a room of temperature 6 8 °F, 30 ° F. Obtain the temperature reading as a function of time. a thermometer reads 17 °F . Later after one minute, the reading of the thermometer is A u = - 51 e - 0.2877 t + 68 u = 68 – 51 e - 0.2942 t U = - (51 e - 0.2942 t + 68 ) U = - 51 e - 0.2877 t + 17arrow_forwardA function of the form P(t) =ab' represents the population (in millions) of the given country t years after January 1, 2000. %3D Part: 0/2 Part 1 of 2 (a) Write an equivalent function using base e; that is, write a function of the form P(t) =Pge". Also, determine the population of each country for the year 2000. Round the population to the nearest hundred thousand. P() = P Population in 2000 |(millions) Country P(1) = ab' Australia P() = 19.0(L0175) P() = Talwan P() = 22.9(1.0034) P(1) = %3D ofarrow_forward(a) Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature varies between 79 and 91 degrees during the day and the average daily temperature first occurs at 8 AM. How many hours after midnight, to two decimal places, does the temperature first reach 81 degrees? (b) Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the high temperature of 75 degrees occurs at 6 PM and the average temperature for the day is 60 degrees. Find the temperature, to the nearest degree, at 10 AM. **PLS HELP ME IN A CLEAR WORKSHEET WITH ACCURATE ANSWERS PLS** I AM SO TIRED TO GETTING WRONG ANSWERS HERE FOR THIS TWO PROBLEMS HELP MUCH APPRECIATED THANKS***arrow_forward
