What is the Fuel Consumption of a Motor After 7 Minutes?

Click For Summary
SUMMARY

The discussion revolves around the fuel consumption of an engine modeled by the equation R = 10 + 10/(2t + 1), where R represents the rate of fuel consumption in kg per minute and t is the time in minutes. Participants are tasked with sketching R as a function of t, calculating the rate of consumption after 7 minutes, determining the limiting value of R as t approaches infinity, and calculating the total fuel consumption in the first 7 minutes. The equation's interpretation is clarified, emphasizing the correct formulation of R for accurate calculations.

PREREQUISITES
  • Understanding of basic calculus concepts, particularly limits and functions.
  • Familiarity with graphing functions and interpreting their behavior.
  • Knowledge of integration for calculating total consumption over a time interval.
  • Ability to manipulate algebraic expressions and solve equations.
NEXT STEPS
  • Learn how to sketch functions and analyze their behavior over time.
  • Study the concept of limits in calculus to understand asymptotic behavior.
  • Explore integration techniques to calculate areas under curves for total consumption.
  • Practice solving similar problems involving rates of change and fuel consumption models.
USEFUL FOR

Students studying calculus, particularly those focusing on applications in physics and engineering, as well as anyone interested in understanding fuel consumption dynamics in mechanical systems.

Homework Statement



I posted int he other section but not sure if that area was a bit high maths

I have this questions an answer to it would be great.
.Q.1 At t minutes after an engine starts, the rate of fuel consumption is Rkg per minute. it is given by R=10+ 10/2t+1.

a) Sketch R as a function of t

b) find the rate of consumption after 7 mins

c) find the limiting value of R as t becomes very large

d) calculate the total consumption in the 1st 7 mins

not sure how to do it
Thank You

You must show an attempt, although it may be something very basic.

First, is this R= 10+ (10/2t)+ 1 or R= 10+ 10/(2t+ 1)

a) Sketch R as a function of t
Okay, have you done that? Just calculate some values and draw the graph.

b) find the rate of consumption after 7 mins

c) find the limiting value of R as t becomes very large

d) calculate the total consumption in the 1st 7 mins
