It seems that the minimum value would be $0$ though. I have no idea how to set up an equation to solve for the max value. Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere. Now finding the range of valid values for the amount of cement is where I feel completely clueless. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. I know that the independent variable is typically plotted on the horizontal axis and it seems that the amount of Cement is a function of the amount of lumber so, I went ahead and said that the amount of Cement should be on the vertical axis. What is the range of valid values for the amount of cement? Potentially, mathematical variables can have any value, but the variables under discussion here are bounded by the real-world context they model.
Which axis should represent the amount of cement? To determine how to spend his budget, Bob graphs the amount of cement he can buy (in kilograms) as a function of the amount of lumber he buys (in square meters). Cement costs $10$ cents per kilogram, and a $10$ centimeter thick board of lumber costs $3$ dollars per square meter. This mission consists of intensive practice on various topics including vectors, matrices. Khan Academy est une ONG qui a pour mission doffrir un enseignement gratuit et de qualité, pour tout le monde, partout. The Precalculus Math Mission is a set of skills on Khan Academy.
