The position of an object at time t is given by s(t) = 7 - 14t. find the instantaneous velocity at t = 7 by finding the derivative.

The velocity of the object is 14m/s in opposite direction for any value of t.

Step-by-step explanation:

The position of an object at time t is given by

Differentiate with respect to t.

We know that the change in displacement with respect to time is known as velocity.

Therefore the velocity of the object is 14m/s in opposite direction for any value of t.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
