Answer:
b
Step-by-step explanation:
When the object hits the ground , the h = 0 , that is
- 16t² + 54 = 0 ( subtract 54 from both sides )
- 16t² = - 54 ( divide both sides by - 16 )
t² = 
( take square root of both sides )
t = 
≈ 1.84 seconds ( to 2 dec. places )

Answer:
Length = 80 m and breadth = 60 m If one moves along the two adjacent sides, one covers 80+60 = 140 m. Diagonal of the rectangle = √ ( length^2 + breadth^2) ...
The price now is (80/100)x70 = (5600/100) = $56;
