Answer:
3.5 seconds
Step-by-step explanation:
h(t) is a quadratic function, it indicate that the object start with initial height (56).
If you want to know when the object hit the ground (h=0) you have to use the quadratic formula
and take the positive root (the negative shows a negative time, so we have to discard it).
In this case: a=-6, b=5 and c=56, then the solve is 7/2=3.5

Answer:
Equation = X*(2/3) = 3/20
Solve for X = 0.23
Step-by-step explanation:
Let, the number be "X"
According to the question,
X*(2/3) = 3/20..........(i)
From equation (i), we can get,
X = (3/20)/(2/3)
or, X = 0.15/0.66
or, X = 0.23
Alternative way,
Let, the number be "X"
According to the question,
X*(2/3) = 3/20..........(i)
From equation (i), we can get,
X = (3/20)/(2/3)
or, X = (3/20)*(3/2)
or, X = 9/40
or, X = 0.23
