Firdavs [7]

Answer:

A. x < -8 (first option)

Step-by-step explanation:

$3 - (2x - 5) < - 4(x + 2)$

$3 - 2x + 5 < - 4x - 8$

$8 - 2x < - 4x - 8$

$- 2x + 4x < - 8 - 8$

Romeo is chucking pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with only a horizontal compon

Genrish500 [490]

Answer:

4.45 m/s

Step-by-step explanation:

Vertical distance, Sy = 5m

The speed of pebble when they hit her window :

Vx = Sx / t

We can obtain t using the relation :

Sy = 1/2 * at²

Where, a = acceleration due to gravity = 9.8m/s²

We can obtain t

5 = 1/2 * 9.8 * t²

5 = 4.9t²

t = √5/4.9

t = 1.01 seconds

Hence,

Speed, Vx = Sx / t

Vx = 4.5 / 1.01

Vx = 4.45 m/s
