Answer:
Step-by-step explanation:
<u>Even function has following property:</u>
<u>It is easy to show this works with the second choice only. All the others don't work:</u>
- g(x) = (x - 1)² + 1
- g(-x) = (-x - 1)² + 1
This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)
The last two choices are not even similarly.
Answer:
8$ per hour
Step-by-step explanation:
This is a fraction equal to
68 $ ÷ 8.5 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 8.5
68 $ ÷ 8.5
= ------------
8.5 hours ÷ 8.5
= 8 $
--------
1 hour
= 8 $
-------
hour
= 8 $ per hour
Answer:
v=sqrt(2KE/m), -sqrt(2KE/m)
Step-by-step explanation:
KE=1/2mv^2
v^2=KE/(1/2m)
v^2=KE/(m/2)
v^2=KE(2/m)
v^2=2KE/m
v=sqrt(2KE/m), -sqrt(2KE/m)
