Question

9 the graph below shows the value of an antique lamp jenna bought since 2020. predict the lamps value in 2028.
answer: ...
a toy rocket was launched vertically. the rockets height after t seconds was presented in the graph below. predict the height of the rocket at the 9th second.
answer: ...

Explanation:

Step1: Determine x - value for 2028

The x - axis represents years since 2020. For 2028, \(x = 2028 - 2020=8\).

Step2: Read value from the graph for lamp

Locate \(x = 8\) on the graph of the lamp's value. The value of the lamp at \(x = 8\) is approximately \(1800\).

Step3: Determine x - value for 9th second for rocket

For the rocket, we want to find the height at \(t = 9\) seconds. So \(x = 9\) on the rocket - height graph.

Step4: Read value from the graph for rocket

Locate \(x = 9\) on the graph of the rocket's height. The height of the rocket at \(x = 9\) is approximately \(54\).

Answer:

Value of lamp in 2028: \(1800\)
Height of rocket at 9th second: \(54\)
