What is the distance between the points (-3,5) and (-3,-9) ?

14

Step-by-step explanation:

The distance between two points is given by

d = sqrt( (y2-y1) ^2 + (x2-x1)^2)

   = sqrt((-9-5)^2 + (-3- -3)^2)

    = sqrt(( -14)^2 +(-3+3)^2)

   = sqrt((-14)^2 +0)

  = sqrt((14)^2)

  = 14

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
