a stone is dropped in a river from a bridge . if it takes 4 seconds to reach of the surface of water, calculate the depth of the water level from the bridge. akso calculate the velocity with which the stone strijes the water surface.

The stone takes 4sec to reach the water level.

initial velocity (u)=0

time(t)=4s

acceleration due to gravity(a)=

9.8(10 approx)

so,its final velocity will be

v=u+at

0+10×4=40

v=40m/s

step-by-step explanation:

10.50 + taxes which added up to 11.50

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
