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:
The answer is 16pi
the circumference of a circle is equal to
so the answer is 6 pi
good luck
Step-by-step explanation:
3h+11/4h+16=19/26
78h+286=76h+304
12h=18
h=3/2
If the square translates to 7 units on the right and 6 units downwards, the following changes will be made:
Point S will have the coordinates of (3, -5).
Point R will have the coordinates of (-1, -5).
Point U will have the coordinates of (-1, -9).
Point T will have the coordinates of (3, -9).
According to the only answer choices in the picture, only (-5, -3) is the only point that lies on a side of the pre-image, square RSTU.
