A particle moves along a straight line. For Osts 5, the position of the particle is given by s(t) = 3t +412 - 13
a) What is the average velocity of the particle over the interval Osts 4?
b) Find a general expression for the velocity of the particle as a function of time, u(t), and determine
the value of v att = 2. Is the particle traveling to the left or the right at this point? Justify your
answer.
c) Find all times t during the interval 0 Sts 5 that the particle changes direction. Justify your
answer.
d) At t = 4, is the speed of the particle increasing or decreasing? Justify your answer.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
