nataly862011 [7]

Answer:

  D.  |C -305,000| ≤ 80,000

Step-by-step explanation:

Such an equation will say that the difference from the average of these values is at most half of their difference.

  | C -(225000+385000)/2 | ≤ (385000 -225000)/2

  |C -305,000| ≤ 80,000 . . . . . matches choice D

Given that xy=3/2 and both x and y are nonnegative real numbers, find the minimum value of 10x (3y/5)
Stells [14]

The munimum value is, at x = 3/10, y = 5 and 10x+3y/5 = 6.

<h3>What are nonnegative real numbers?</h3>
  • Non-negative real numbers are the set of positive real numbers that are bigger than 0 (zero).
  • That is, the true values are either positive or negative.
  • The collection will include numbers such as 0, 1, 2, 3, 4, 5, and so on.

To find the minimum value of 10x (3y/5):

Given - y = 3/(2x)

So, we want the bare minimum of,

  • = 10x + 3/5 × 3/(2x)
  • = 10x + 9/(10x)

Take the derivative to obtain:

  • = 10 - 9/(10x^2)

When you set it to zero, you get:

  • = 100x^2 - 9 = 0
  • = (10x-3)(10x+3) = 0
  • = x = ± 3/10

So, at x = 3/10, y = 5 and 10x + 3y/5 = 3 + 3 = 6.

Therefore, the munimum value is, at x = 3/10, y = 5 and 10x+3y/5 = 6.
