Maximum value's going to be? Well, let's look at this first one. The expression make it easy for us to find what the
Now, what they're asking us, or one way to think about it is, which of these show the maximum value? Which of these forms of Of these, so these are all just algebraic manipulations Now, this is gonna be the same thing as negative w squared plus, I'm just distributing the negative sign, plus 100 w minus 2500 plus 2500, which these two thingsĬancel each other out, and you're left with thisĮxpression right over here. They're equivalent expressions, or we could take, for example, this first one right over here, this would be the same thing as negative, let's see w minus 50 squared is w squared minus two times 50 times w, Way that they phrased it, but they're saying that these are all equivalent expressions Which the area is a maximum? So that's an interesting Which of the followingĮquivalent expressions displays, as a constant or a coefficient, the value of the width for Us, where they tell us what area as a function Given by the equation below where w is the Purchased 200 feet of fencing to make a rectangular
