Algebra 1 grade 9.
can anyone me answer this question?

the brightness of a star is measured in magnitudes. the lower the magnitude, the brighter the star. a magnitude 9 star is 2.51 times as bright as a magnitude 10 star. a magnitude 8 star is 2.51 * 2.51 or (2.51)2 as bright as a magnitude 10 star.

(note: 10 - 8 = 2. get it? )

a. how many times as bright is a magnitude 3 star as a magnitude 10 star?

b. write an expression to compare a magnitude m star to a magnitude 10 star.

c. a full moon is magnitude -13, approximately. does your expression make sense for this magnitude? explain.

627.65 times

2.51^(10 - m) times

Yes, it makes sense

Step-by-step explanation:

Given that,

A magnitude 9 star is 2.51 times as bright as a magnitude 10 star

To find

How many times as bright is a magnitude 3 star as a magnitude 10 star

10 - 3 = 7

2.51^7

627.65 times

Expression to compare a magnitude m star to a magnitude 10 star

2.51^(10 - m) times

Yes, it makes sense as a full moon is magnitude -13

so,

2.51^(10 - (-13))

2.51^(23)

1557742231 times

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
