Answer:
The absolute brightness of the Cepheid star after a period of 45 days is -5.95
Step-by-step explanation:
Since the absolute magnitude or brightness of a Cepheid star is related to its period or length of its pulse by
M = –2.78(log P) – 1.35 where M = absolute magnitude and P = period or length of pulse.
From our question, it is given that P = 45 days.
So, M = –2.78(log P) – 1.35
M = –2.78(log 45) – 1.35
M = –2.78(1.6532) – 1.35
M = -4.60 - 1.35
M = -5.95
So, the absolute magnitude or brightness M of a Cepheid star after a period P of 45 days is -5.95
The cone's volume is 2 times the volume of the cylinder. A cone's volume is normally 1/3 the volume of a cylinder, but because its height is 6 times larger than that of the cylinder, it is 6/3, or 2, times the volume of the cylinder.
Hope this helps!

Take the absolute value of the difference of the two number
| -2 1/5 - 4.35|
Answer:
Rational
Step-by-step explanation:
If you multiply 5 by 2 you get 8. 8/5 is 1.6. it isn't an ongoing number therefore is is rational
