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
No, because 13.2 times 6=79.2
79.2 times 8=633.6
Answer:
as per ur ques if we take x as number then we get algebraic expression as
2x - 4
brainliest?
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
