In this lesson, we will learn how to apply limits in real-life applications.

Q1:

A companyβs profit in LE as a function of its advertisement expenditure π₯ is π(π₯)=0.2π₯+34π₯+123ο¨. Determine the profit as π₯ approaches 100 LE.

Q2:

In the figure below, points π΄ and π΅ lie on a circle of center π and radius 1. Point πΆ is chosen so that ππΆβπ΄π΅. Setting π₯ to the length of ππΆ and π¦ to the length of π΄π΅, what is the limit of π¦ as π₯β0?

Q3:

Using the figure below, determine the limit of length π¦ as the measure of π tends to π2.
