Answer:
(C)
Step-by-step explanation:
Given the distance, d(t) of a particle moving in a straight line at any time t is:

To find an expression for the instantaneous velocity v(t) of the particle at any given point in time, we take the derivative of d(t).

The correct option is C.
Answer:
<h2>x = 4</h2>
Step-by-step explanation:
ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:

We have:
LM = 3 + 9 = 12
PM = 9
NM = x + 12
QM = 12
Substitute:
<em>cross multiply</em>

<em>divide both sides by 9</em>

<em>subtract 12 from both sides</em>
