QuestionGraph the inequality for elevator speeds outside the range of 116 to 124 feet per minute: or .
Studdy Solution
STEP 1
Assumptions1. The elevator's full speed range is between116 and124 feet per minute. . We want to graph an inequality that represents the speeds at which the elevator is outside of this range.
STEP 2
We can represent the speeds at which the elevator is outside of its full speed range using two inequalities one for speeds less than116 feet per minute and one for speeds greater than124 feet per minute.
STEP 3
We can combine these two inequalities into one by using the logical OR operator, represented by the symbol ∨.
STEP 4
Now, we can graph this inequality on a number line.1. Draw a number line and mark the points116 and124.
2. Since the inequality is strictly less than116 and strictly greater than124, we use open circles at these points.
3. Shade the region to the left of116 and to the right of124 to represent the speeds at which the elevator is outside of its full speed range.
