Answer:
She should aim 6 feet down the wall
Explanation:
The diagram attached sketches the situtation.
Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.
Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:
x/4 = y/2 ⇒ x = 2y
You have other equation:
x+ y = 18
Substitute
2y + y = 18
3y = 18
y = 18/3
y = 6 ← this is the distance down the wall where the ball should hit
x = 2(6) = 12
Then, she should aim 6 feet down the wall.
Answer:
the first option
Step-by-step explanation:
local max is the highest point which is (-1,1.17)
and local min is the lowest point which is (2,-3.33)
NO. It's FALSE.
therefore 0.3801 > 0.3711
Answer:
2
Step-by-step explanation:
the mode is the one that appears the most, most common one
