Two positive numbers x and y, with the maximum value 4, add up to 5. what is the difference between the maximum and minimum valu
Mnenie [13.5K]

Answer:

1023

Step-by-step explanation:

Positive numbers are numbers that are greater than 0.

As maximum value of numbers x and y is 4,

x\leq 4,y\leq 4      ....(i)

So,

x^2y^3\leq 4^2 4^3=1024

So, maximum value of the product x^2y^3 is 1024.

Also, its given that sum of numbers x and y is 5, so x+y=5   ...(ii)

On using equations (i) and (ii), we get

1\leq x,1\leq y

So,

1\leq x^2y^3

Therefore, minimum value of the product is 1.

Difference between the maximum and minimum value of the product =  maximum value of the product x^2y^3 - minimum value of the product

=1024 - 1 = 1023

What's the numerator for the following rational expression? 6/t+7/t=?/t
Svetlanka [38]

The numerator for the following rational expression is 13

<h3>How to determine the numeration?</h3>

The rational expression is given as:

6/t + 7/t

Take the LCM of the denominator;

The LCM of t and t is t

So, we have:

6/t + 7/t = (6 + 7)/t

Evaluate the sum

6/t + 7/t = 13/t

13 is the numerator, while t is the denominator

Hence, the numerator for the following rational expression is 13
