1 2/3 + 3 1/3 = 5/1
5 5/6 - 5/1 = 5/6
5/6 was left
The answer is phoenix is located at (-7,-10) it is written like this because you always have the x coordinate then the y coordinate
This written as an expression is 7 >= w > -1
Hope this helps!
Let α represent the acute angle between the horizontal and the straight line from the plane to the station. If the 4-mile measure is the straight-line distance from the plane to the station, then
sin(α) = 3/4
and
cos(α) = √(1 - (3/4)²) = (√7)/4
The distance from the station to the plane is increasing at a rate that is the plane's speed multiplied by the cosine of the angle α. Hence the plane–station distance is increasing at the rate of
(440 mph)×(√7)/4 ≈ 291 mph
