The distance h a body will move in a free fall is expressed by the formula h = 1/2 gt 2. if g = 980 cm per sec per sec and t = 20 sec, the distance h is

 196000 cm

Step-by-step explanation:

Here, the given formula,

Where, g is the gravitational acceleration,

t is the time in second,

Here, g = 980 cm per sec  and  t = 20 seconds,

Therefore,

Thus, the required height = 196000 cm

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
