Answer:

acute angle
x = 25

Step-by-step explanation:

The angle shown is 75°. It is less than 90°, so is an acute angle. (The diagram is misleading in that respect.)

The two marked angles are vertical angles, so have the same measure.

3x° = 75°

x = 25 . . . . . . . . divide both sides by 3°

The height that a properly inflated basketball bounces decreases exponentially by 27.8% with each subsequent bounce after the in

n200080 [17]

Answer:

$H (b) = 0.722^b(6)$

Step-by-step explanation:

The first time the basketball bounces it reaches a height of $(1-0.278)(6) = (0.722) (6)$ .

The second time the basketball bounces it reaches a height of $(0.722) (0.722) (6) = [(0.722) ^ 2] (6)$ . Therefore, after b rebounds the height that the basketball will reach is given by:

$H (b) = 0.722^b(6)$
