The Uniqe Shoppe sells personalized telephones. Its weekly cost function is C(x)=28x+650. At
the break=even point, x=65 phones per week. What is the revenue function?
Solution
The Uniqe Shoppe sells personalized telephones. Its weekly cost function is C(x)=28x+650. At
the break=even point, x=65 phones per week. What is the revenue function?
AT BREAK EVEN
COST=REVENUE
COST = 28X+650
REVENUE=S*X
WHERE
S=SALE PRICE PER UNIT
X= NO. SOLD.=65
SO WE GET
S*65=28*65+650
S=38
HENCE THE REVENUE FUNCTION IS
R=38X..............ANSWER.
The unit impulse function is not physically realizable. In fact, it .pdf
1. The unit impulse function is not physically realizable. In fact, it is not a normal mathematical
function at all. So, why is the unit impulse function of interest to engineers?
Solution
The continuous time unit impulse function, also known as the Dirac delta function,
is of great importance to the study of signals and systems. Informally, it is a function with
infinite height ant infinitesimal width that integrates to one, which can be viewed as the limiting
behavior of a unit area rectangle as it narrows while preserving area. It has several important
properties that will appear again when studying systems.
