(a)
Write compound inequalities for the wind speeds of category 3 and category 4 hurricanes.
(a)
Answer to Problem 37PPS
Compound inequalities are:
Explanation of Solution
Given:
Concept Used:
Category 3: The wind speed 111 − 130
Category 4: The wind speed 131 − 155
Thus, the compound inequalities for the wind speed of category 3 and 4 are:
(b)
Find the intersection of the two graphs of the inequalities you found in part a.
(b)
Answer to Problem 37PPS
No Intersection: Ø
Explanation of Solution
Given:
Concept Used:
Category 3: The wind speed 111 − 130
Category 4: The wind speed 131 − 155
Category ends at 130 mph and category starts from 131mph.
Category 3:
Category 4:
So, there is no intersection.
Thus, there is no intersection of the two graphs of the inequalities we found in part a.
