Arrange the following polynomial into descending order and identify the 3rd term. 18x + 2x3 − 3x2 + 10 (2 points) select one: a. 18x b. 2x3 c. −3x2 d. 10

18x

Step-by-step explanation:

The highest power of x is x^3.  Note that you must use " ^ " to denote exponentiation.  The next highest power is x^2, followed by x and x^0 (=1).  Thus, in descending order by power of x, we have 2x^3 - 3x^2 + 18x + 10.  Here the third term is 18x.

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.
