Can Somebody help me?

Part 3 Graph B Part 4 Graph C Part 5 Graph A

Step-by-step explanation:

We can use the process of elimination to eliminate b because in the text it states she starts at home so she should be at 0. We next can eliminate A because it says she stops however in graph a there is no flat line to suggest a period of time with no movement. So we end up with B.

Part 4 is C because it  says she starts not at home so we look for the graph not at 0.

Part 5 Graph A is not used. In this graph she could be running 3 miles then turn around and run back those 3 miles

Hope this helped :)

cosine

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
