19. What is the distance between P(-3, 10 ) and Q( 12, -6 )? Round to the nearest hundredth if necessary. d=

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

The answer is 12,6 u.c.

Step-by-step explanation:

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
