Question

problems 5–7: this table shows the population of a city from 1988 to 2016. 5. determine the average rate of change for p(t) between 1992 and 2000 6. state two values of t that create an interval with a negative rate of change. 7. state two values of t that create an interval with a positive rate of change. 8. match each interval to its average rate of change. interval average rate of change a. x to y $\frac{1}{5}$ b. y to z $\frac{1}{4}$ c. x to z $\frac{1}{6}$ 9. jada is walking to school. the function d(t) gives the distance from school, in meters, t minutes since jada left home. which equation represents this statement? jada is 600 meters from school after 5 minutes. a. $d(5) = 600$ b. $d(600) = 5$ c. $t(5) = 600$ d. $t(600) = 5$ 10. complete the arithmetic sequence with the missing terms ____ 6 ____ 22, 30

Response
Problem 5:

Step 1: Recall the formula for average rate of change

The average rate of change of a function \( p(t) \) between \( t = a \) and \( t = b \) is given by \( \frac{p(b)-p(a)}{b - a} \).

Step 2: Identify the values for 1992 and 2000

From the table, in 1992 (\( t = 1992 \)), \( p(1992)=42700 \), and in 2000 (\( t = 2000 \)), \( p(2000)=33700 \). The time difference \( b - a=2000 - 1992 = 8 \).

Step 3: Calculate the average rate of change

Substitute into the formula: \( \frac{p(2000)-p(1992)}{2000 - 1992}=\frac{33700 - 42700}{8}=\frac{-9000}{8}=- 1125 \)

Brief Explanations

A negative rate of change occurs when the population decreases over time, i.e., \( p(t_2)<p(t_1) \) for \( t_2 > t_1 \). Looking at the table, from 1992 (\( p = 42700 \)) to 1996 (\( p = 33100 \)), the population decreases. So \( t_1 = 1992 \) and \( t_2 = 1996 \) (other valid pairs: 1992 - 2000, 2008 - 2012 etc.).

Brief Explanations

A positive rate of change occurs when the population increases over time, i.e., \( p(t_2)>p(t_1) \) for \( t_2 > t_1 \). From 2000 (\( p = 33700 \)) to 2004 (\( p = 45000 \)), the population increases. So \( t_1 = 2000 \) and \( t_2 = 2004 \) (other valid pairs: 2004 - 2008, 2012 - 2016 etc.).
