r represents the rate the electric company charges per kilowatt-hour.
Total charged to Zhao was 63.25 out of which 3.50 is administrative charge (fixed).
- Total charge consists of "administrative charge" + "charge per kilowatt hours*hours used

Answer:
Water in container B will be at 6.own
Step-by-step explanation:
calculate the volume in cont. A
VoA=400×6
=2400cm cube
VoB=420ml
=420cm cube [1ml=1cm cube]
now add both volumes
V=2400+420
=2820cm cube
Now,
2820 cm cube in jar B so
2820=420×h
h=6.71
A, c, and d
plug in each x in the equation and it should equal the y value
Answer:

Step-by-step explanation:
Answer: Period = 4
Amplitude = 3
<u>Step-by-step explanation:</u>
Period is the interval of one "cycle" before the pattern repeats.
If you notice that when x = 0, y = -4.
When does the pattern repeat (reach -4 again)?
Answer: when x = 4.
So the interval of one "cycle" is 4 units --> Period = 4.
