The rate at which the distance increases
Their movement forms a right triangle and the distance between them is the hypotenuse.
At
and 
The distance between them is:




After 1 hour, their new position is:
New = Old + Rate * Time


And:


So, the distance between them is now:




The rate of change is:



Answer:
In triangle AB, A and B are acute angles so. AC and BC are right angles.
Sin A = 10/13
13 is the hypotenuse side and 10 is the opposite side.
To find cos A.
From pythagorean theorem:
Step-by-step explanation:
Parallel lines have the same slope.
The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.
So, if the input is 15.4, the output will be
