a) To find: Write an inequality that represents the heights of every other person who has ever lived.
Given information:
The tallest person who ever lived was approximately 8 feet 11 inches tall
Use 1 feet = 12 inches
8 feet 11 inches =8+1112=96+1112=10712 feets
Let x denotes height of a person.
As the tallest person who ever lived was approximately 8 feet 11 inches tall,
x10712=8.9
x8.9
b) To verify: if 9 feet is a solution of the inequality x8.9
Given information: The tallest person who ever lived was approximately 8 feet 11 inches tall
Formula used: 1 feet = 12 inches
Proof:
x8.9
Put x=9
98.9 which is not true.
Thus, 9 feet is not a solution of x8.9

Step 1To write the sentence as an inequality, consider the variables and numbers that go on the left-hand and right-hand side. Make sure to identify the type of inequality should be used as well.Step 2a. Since the tallest person is measured at 8 feet 11 inches, then every other person's height is less than this given height, therefore, the inequality for this should be x<8 feet 11 inchesb. Since 9 feet is greater than the given inequality, then it is not a solution of the inequality.

Aurora is planning to participate in an event at her school's field day that requires her to complete tasks at various stations in the fastest time possible. To prepare for the event, she is practicing and keeping track of her time to complete each station. The x-coordinate is the station number, and the y-coordinate is the time in minutes since the start of the race that she completed the task. (1,3),(2,6),(3,12),(4,24)
Part A: Is this data modeling an algebraic sequence or a geometric sequence? Explain your answer.
Part B: Use a recursive formula to determine the time she will complete station 5.
Part C: Use an explicit formula to find the time she will complete the 9th station.
