Answer:
h = 2.25 m
Step-by-step explanation:
<u><em>Given:</em></u>
Speed = v = 12 ft/sec
Acceleration due to gravity = g = 32 ft/sec²
<u><em>Required:</em></u>
Height = h = ?
<u><em>Formula:</em></u>
v = 
<u><em>Solution:</em></u>
For h, the formula will be:
=> h = 
=> h = 
=> h = 
=> h = 2.25 m
40! / 30! = 40*39*38*37*36*35*34*33*32*31
dividing this by 10! 10*9*8*7*6*5*4*3*2*1
= 4*13*19*37*17*11*4*31
= 847,660,528
The correct answer is B=4
Absolute value only removes the negative signs. Just multiply the numerator and the denominator
