Answer:
The speed of the periodic wave is 3 meters per second.
Step-by-step explanation:
Given that:
Wavelength of the periodic wave = 1 m
Frequency of the periodic wave = 3 Hz
We have to find the speed of the wave.
Speed of wave = Wavelength * Frequency of wave
Speed = fλ
Speed = 1*3
Speed = 3 m/s
Hence,
The speed of the periodic wave is 3 meters per second.
Answer:
10 years
Step-by-step explanation:
Given
Decline from (0,h) to (10,0)
See attachment for graph
Required
Determine the age when height = 0
The function of the graph is represented as: (age, height)
So, we need to read from the graph the corresponding value of age (on the x-axis) when height = 0 (i.e. the y-axis)
From the attached graph;
when 
<em>Hence, the age of the car is 10 years</em>
