Question

What is a real-world example when the solution of a system of inequalities must be in the first quadrant?

Answer 1

x and y must both be positive, so y>1 and x>2 would be in quadrant 1

Answer 2

Suppose you have a $1000000 budget to produce cars and trucks. Each car costs $2000 to build and each truck costs $4000 to build. Also assume there is a fixed amount of steel available and already paid for: 500000 pounds of steel. Finally assume each car requires 1100 pounds of steel and each truck requires 1500 pounds. If you graph these constraints you will get two linear inequalities which must both be satisfied, and the only solutions which make sense are for values of x and y (number of cars and trucks built) which are nonnegative. I.e. solutions must be in the first quadrant.

Answer 3

use radio waves in absolute value

since there ar no such thing as radio wave's negativity in hertz... i would suggest this example

Answer 4

control
