A passenger jet passed through an altitude of 14,000 feet 8 minutes after takeoff and was climbing at a rate of 1,250 feet per minute. Find a linear model for the altitude A (in ft) of the jet t minutes after takeoff.
A =
Use your model to predict the altitude (in ft) of the jet 28 minutes into the flight.
Homework Answers
Since the plane reached 14000 ft in 8 minutes but climbs at a rate of 1250 ft per minute. Thus, the plane was at 4000 ft before the flight takeoff.
Hence, A=1250t+4000
Putting t=28 we get A=39000 ft
Hence after 28 minutes, the jet is flying at 39000ft.

Listed below are altitudes (thousands of feet) and outside air temperatures (°F) recorded during a flight. Find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. There is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. For the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet). 25 Altitude Temperature 3 56 8 38 17...

Suppose that a room containing 1900 cubic feet of air is originally free of carbon monoxide (CO). Beginning at time t 0, cigarette smoke containing 3% CO is introduced into the room at a rate of 0.3 cubic feet per minute. The well- circulated smoke and air mixture is allowed to leave the room at the same rate. Let A(t) represent the amount of CO in the room (in cubic feet) after t minutes. (A) Write the DE model for...

A 4 foot spring measures 8 feet long after a mass weighing 8 pounds is attached to it. The medium through which the mass moves offers a damping force numerically equal to 2^1/2 times the instantaneous velocity. Find the equation of motion if the mass is initially released from the equilibrium position with a downward velocity of 9 ft/a. (Use g =32 ft/s^2 for the acceleration due to gravity.) a) Find the time at which the mass attains its extreme...
