Given information:
and
Revenue:
The dot product is given by,
Substituting the values-
Interpretation: The dot product gives us the total cost of cellular phones produced by
the company.
(b)
To identify the vector operation used to increase the wages by
(b)
Answer to Problem 73E
ft2
Explanation of Solution
Given information:
The lengths of the sides of a triangular parcel of land are approximately 200 feet, 500 feet and 600 feet.
By rule of scalar multiplication,
Therefore, to increase the prices by 5%, we use vector operation called, scalar multiplication.
Thus, gives the new total cost of cellular phones produced by the company.
Hence,
a) The dot product gives us the total cost of cellular phones produced by the company.
b) To increase the prices by 5%, we use vector operation called, scalar multiplication.
