She’s drinking 96 fluid ounces a day, and there’s 8 fluid ounces in a cup so she’s drinking 12 cups of water in a day
Answer:
−2.333
Step-by-step explanation:
-7 - 3y = -1 • (3y + 7)
y = -7/3 = -2.333
$ 1.85 you divide 22.20 by 12
It's basically like subtracting .
15-4 = 11 . So 11 is your answer
Cos x = -12/13
sin x = -sqrt(13^2 - 12^2) / 13 = -5/13
tan x = 5/12
tan x/2 = (1 - cos x) / sin x = 1 - (-12/13) / -5/13 = 25/13 * -13/5 = -5
2sin^2 x/2 = 1 - cos x = 1 - (-12/13) = 25/13
sin^2 x/2 = 25/13 / 2 = 25/26
sin x/2 = 5/√26
sin x/2 / cos x/2 = tan x/2
cos x/2 = sin x/2 / tan x/2 = 5/√26 / -5 = -1/√26
sin x/2 = 5/√26
cos x/2 = -1/√26
tan x/2 = -5
