Among all pairs of numbers with a sum of 215, find the pair whose product is maximum. Write your answers as fractions reduced to
valentina_108 [34]

Answer:

Step-by-step explanation:

This is calculus, but I don't get fractions in the end. To maximize or minimize any function, you need to find the derivative of it, set it equal to 0, then solve for the critical values.

Our given equation is

x + y = 215 and we want to maximize the product, xy. Therefore,

y = 215 - x so its product in terms of x is

x(215-x) which is

215x -x^2.  The derivative of this is

215 - 2x. Set it equal to 0 to maximize it.

215 - 2x = 0 so

-2x = -215 and

x = 107.5.

Sub this in to solve for y:

y + 107.5 = 215 and

y = 107.5

The product is 11556.25, not that you need it.

What is the answer for 805 tens = with place value chart
alexandr1967 [171]
In the given problem, the numerical value of 805, which is in the tens place, we can first elaborate and clearly specify the order of numbers by using the expanded form: <span><span>1. </span><span> 800 = eight hundred / hundreds</span></span> <span><span>2. </span><span> 0 = zero / tens</span></span> <span><span>3. </span><span> 5 = five / ones </span></span> Conclusively the tens value of the number is zero or none, since zero is not a real number then it can’t be considered but nevertheless, the value is 0 expressed with respect to the whole numbers.
