Answer:
For example, a common equation, y=mx+b y = m x + b
Step-by-step explanation:
is a linear function because it meets both criteria with x and y as variables and m and b as constants.
Answer:
side length= 8 meters
diagonal = 11.31
Step-by-step explanation:
take the square root of 64 to find the length of the side, which is 8.
Then do 8 times the square root of 2 to find the diagonal.

First, we calculate the water pipe length (AC):
The cost of laying across water is twice (2 times) laying on land.
So, the total cost (C) is:
Differentiate
To find the most economical cost, we simply minimize C' by equating C' to 0
Cross multiply
Take square of both sides
Collect like terms
