The luminosity of a star can be calculated by using the following equation. In the luminosity equation, represents the luminosity in watts, represents the radius of the star in meters, represents a constant equal to 5.67 × 10-8 Wm-2K-4, and represents the surface temperature in Kelvins.

What is the approximate radius of a star with a luminosity equal to 2.532 × 1021 W and a surface temperature of 3,000 K? (Use = 3.14)

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
