Don’t really get these very much. Can anyone help ?
1 answer:
Answer:
23) has an amplitude greater than the period of
/Both lines have the same period/There are no shifts of any kind between both lines.
24) Both lines have the same amplitude/ has a period less than period of
/There are no shifts of any kind between both lines.
25) Both lines have the same amplitude/Both lines have the same period/There is an horizontal shift between and
.
26) Both lines have the same amplitude/Both lines have the same period/There is a vertical shift between and
.
Step-by-step explanation:
We proceed to describe succintly all differences and simmilarities between and
in each case:
23) has an amplitude greater than the period of
/Both lines have the same period/There are no shifts of any kind between both lines.
24) Both lines have the same amplitude/ has a period less than period of
/There are no shifts of any kind between both lines.
25) Both lines have the same amplitude/Both lines have the same period/There is an horizontal shift between and
.
26) Both lines have the same amplitude/Both lines have the same period/There is a vertical shift between and
.

Only selections B and D give a maximum height of 13 at t=3. However, both of those functions have the height be -5 at t=0, meaning the ball was served from 5 ft below ground. This does not seem like an appropriate model.
We suspect ...
• the "correct" answers are probably B and D
• whoever wrote the problem wasn't paying attention.
