A function assigns the values. The absolute magnitude of a star that has a period of 62 days is -6.3328.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
The relationship between the brightness of a Cepheid star and its period, or length of its pulse, is given by
M = − 2.78 (log P) − 1.35,
Given the absolute magnitude of a star that has a period of 62 days is,
M = − 2.78 (log 62) − 1.35
M = -6.3328
Hence, the absolute magnitude of a star that has a period of 62 days is -6.3328.

Let us say that the variable x is the amount of number of
hours Leo spent at each of the weight machines.
Since there are 5 machines, therefore = 5 x
Adding this variable to the number of hours spent on the
treadmill will give the total number of hours Leo spent at the gym. That is:
5 x + 2 / 3 = 1 3 / 4
5 x + 2 / 3 = 7 / 4
Therefore the correct equation is:
5 x + 2 / 3 = 7 / 4
Or
if no denominator, we multiply the whole equation with 12 so that:
(5 x + 2 / 3 = 7 / 4) * 12
60 x + 8 = 21
or
60 x = 13
Solving for x will give:
x = 13 / 60
x = 0.217 hours

I’d love to help! so we know that the angles of a triangle all add up to 180. we already have one of the angles found and a method to solve it. so 180=90+(2x+36)+(3x+14) would be a good equation. now to simplify it a little bit we can subtract 90 from both sides and have 90=(2x+36)+(3x+14) as an even more simplified equation. now we just need to solve for x by first combining like terms on the one side. so that will simplify to 90= 5x+50.
subtract 50 from both sides now
40=5x
divide by 5
x=8.
yayyy we got x now we can just plug it into the equations. so 2(8)+36 for the one angle. 16+36= 52. so mnext angle we can plug in 8 for x again. 3(8)+14. simplify to 24+14 which is 38. so m
