Answer:
19.2
76.8
Step-by-step explanation:
density × volume = mass
mass = 62.4 × (pi × (40/2)² × h)
mass = 78,374.4h
WD = m×9.8×h = 9.8mh
WD = 768,069.12h²
At h = 5
WD = 768,069.12×5²
= 19,201,728 ft-lb
= 19.2 million ft-lb
At h = 10
WD = 76,806,9.12 × 10²
WD = 76,806,912 ft-lb
= 76.8 million ft-lb
2x+16= 3(x-9)
2x+16= 3x-27
3x-2x^^
16= x-17
16+17
x= 33
Neither A nor B are True
the answer is D
that is R ND Q re on the same line as well as S ND
