The spectroscopic parallax of a star is the difference between the apparent magnitude, which is the brightness of light from the star reaching Earth, and the absolute magnitude, which is the intrinsic brightness. The spectroscopic parallax S can be used to calculate the distance d, in parsecs, from Earth to the star. The relationship is
.
A: Find the spectroscopic parallax of a star that is 10.96 parsecs from Earth.B: Find the distance from Earth of a star that has a spectroscopic parallax of 5.C: Star A is 5 times as far from Earth as star B. How do their spectroscopic parallaxes compare?

Solve the SSA triangle. Indicate whether the given measurements result in no triangle, one triangle, or two triangles. Solve the resulting triangle. Round the answer to the nearest tenth.B = 22°, b = 16.8, a = 22.42
A. A = 150°, C = 8°, c = 6.2 B. No triangle exists. C. Solution 1: A = 30°, C = 128°, c = 35.3 Solution 2: A = 150°, C= 8°, c = 6.2 D. A = 30°, C = 128°, c = 35.3
