Answer:
0, 1, 2
Step-by-step explanation:
The solution to a system of equations given graphically is at the intersection of the individual graphs.
Graph (1)
There is no intersection between the 2 graphs so no solution
Graph (2)
There is one point of intersection between the 2 graphs so 1 solution
Graph (3)
There are two points of intersection between the 2 graphs so 2 solutions
Answer:
3.5 to 20.5 hours
Step-by-step explanation:
The range of the sine function is -1 to 1, so the range of H will be ...
-8.5 +12 = 3.5
to
8.5 +12 = 20.5
The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.
