Two airplanes leave an airport at the same time. One airplane travels at 400 km/h and the other at 525 km/h. After 2 hours, the planes are 900 km apart. Determine the angle between their paths. Draw a diagram to help with your solution. Hint: distance = (speed)(time) (This is trigonometry)

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

b. b < 1 might be the correct answer

1. 523.33 cubic inches

2. 113.04 cubic inches.

3. 17.41.

4. 16.49

i think this should be your answer

hope i
