Aperson is walking briskly in a straight line. the figure shows a graph of the person’s position as a function of time . what is the person’s average velocity between t = 6 s and t = 10 s?

We are given graph of position of a person

For finding velocity , we will have to find slope of the given curve

Since, we have to find average velocity between t=6s to t=10s

We can see that there are shape of curve between t=6 and t=10

t=6 to t=8:

There is a inclined line

we can select any two points on that line and find slope

(5,1) and (8,6)

now, we can find slope using formula

now, we can plug values

so, first velocity is

t=8 to 10:

We can see that there is horizontal line

so, we can select any two points

(8,6) and (10,6)

now, we can find slope using formula

now, we can plug values

so,

Average velocity between t=6 and t=10:

now, we can find average velocity

so,

average velocity is 0.8m/s...........Answer

i believe the answer is the polygon, heptagon.

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
