What is the luminosity class (Supergiant I, Bright Giant II, Giant III, Sub-Giant IV, Main Sequence V) and spectral type (OBAFGKM) of a star with an effective temperature of 6000 K and a luminosity of 1 LSun?

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
