@bobross plz i have another question
a particle moves on a line away from its initial position so that after t hours it is s = 6t^2 + 2t miles from its initial position. find the average velocity of the particle over the interval [1, 4]. include units in your answer.

Average velocity is 32 miles/hr.

Step-by-step explanation:

Given that a particle moves on a line away from its initial position so that after t hours it is   miles from its initial position.

We have to find the average velocity of the particle over the interval [1, 4].

As, average velocity is the change is position over the change in time.

∴

                            =

Hence, average velocity is 32 miles/hr.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
