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,
....(i)
So,
So, maximum value of the product 
is 1024.
Also, its given that sum of numbers x and y is 5, so 
...(ii)
On using equations (i) and (ii), we get
So,
Therefore, minimum value of the product is 1.
Difference between the maximum and minimum value of the product = maximum value of the product - minimum value of the product
=1024 - 1 = 1023
In a rhombus, the diagonals meet at right-angles, and they bisect each other, namely they cut each other in half, check the picture below.
thus we can use the pythagorean theorem to get one side, keeping in mind that, slanted as it may be, all sides in a rhombus are equal in length.
(8,9)
To find the midpoint of coordinates is adding all the X axis coordinates and dividing it by 2 (9+7 divided by 2=8)
Same goes for the Y axis (5+13 divided by 2= 9)
Subtract 15 from 8 and you'll get if then you take 10- your answer which in this case is 7 and you get 10-7=3
hope this helpful and what you needed.
