Answer:
First, a rational number is defined as the quotient between two integer numbers, such that:
N = a/b
where a and b are integers.
Now, the axiom that we need to use is:
"The integers are closed under the multiplication".
this says that if we have two integers, x and y, their product is also an integer:
if x, y ∈ Z ⇒ x*y ∈ Z
So, if now we have two rational numbers:
a/b and c/d
where a, b, c, and d ∈ Z
then the product of those two can be written as:
(a/b)*(c/d) = (a*c)/(b*d)
And by the previous axiom, we know that a*c is an integer and b*d is also an integer, then:
(a*c)/(b*d)
is the quotient between two integers, then this is a rational number.
Answer:
The player's vertical jump ability is 15 inches
Step-by-step explanation:
The mark on the scale which the player's hand can reach while standing = 4-in which is the standing reach
The mark on the scale the player's hand can reach when jumping = 19-in
Therefore, the player's vertical jumping ability is given as the difference between the height the players hand can reach when jumping and the height which the player's hand can when standing,
Which gives;
The player's vertical jump ability = 19 inches - 4 inches = 15 inches
The player's vertical jump ability = 15 inches.
