Answer:

Step-by-step explanation:
Let suppose that airliners travel at constant speed. The equations for travelled distance of each airplane with respect to origin are respectively:
First airplane

Where t is the time measured in hours.
Since north and west are perpendicular to each other, the staight distance between airliners can modelled by means of the Pythagorean Theorem:

Rate of change of such distance can be found by the deriving the expression in terms of time:

Where
and
, respectively. Distances of each airliner at 2:30 PM are:


The rate of change is:


To find your answer you need to do y divided by x.
since x = -12 and y = 3 you do 3 ÷ -12 and you get -0.25, this as a fraction is -1/4 and this is your answer!
Hope this helped!
Can or bottle? A can will be the calculation for the surface area of a cylinder which is A=

if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that
Answer is in the screenshot.
48 stamps because 29-5=24 , 24x2=48
