Susan drove to visit a friend. She drove 345 miles in 5 hours and 45 minutes. What was her

average speed, to the nearest tenth of a mile per

hour?

Step-by-step explanation:

Given

Required

Determine the average speed

This is calculated as thus:

Convert time to hour:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
