Answer:
Given :A star in the sky appears to move by 12 arc seconds over the course of 6 months.
To Find :Convert this number into first arc minutes then degrees.
Solution:
60 arc seconds = 1 arc minute
1 arc seconds =
arc minute
12 arc seconds =
arc minute
12 arc seconds =
arc minute
So, 12 arc seconds =
arc minute
Now convert it into degrees
60 arc minute = 1 degree
1 arc minute =
degree
arc minute =
degree
arc minute =
degrees
12 arc seconds =
degrees
(x+4)^2 / 9 - (y+3)^2 / 16 = 1
a^2 = 16 and b^2 = 9
a = +4 and -4
b = +3 and -3
Center is (-4, -3)
Vertices is (-4 + a, -3) and (-4 - a, -3)
Vertices is (-1, -3) and (-7, -3)
