Answer: Thursday
Step-by-step explanation:
Answer:
The solutions the equation 1 are -1.3 and 2. The solutions to equation 2 are -1 and 0.
Step-by-step explanation:
Isolate the absolute value for equation 1. Then, set two equations equal to 5 and -5.
3x - 1 = 5 and 3x - 1 = -5
Solve for x in both and you would get -1.3 and 2.
Do the same for equation 2.
2x + 1 = -1 and 2x + 1 = 1
Solve for x and you would get -1 and 0.
Cos (B) = (a^2 + c^2 -b^2) / (2 * a * c)
cos (B) = (11^2 +17^2 -12^2) / (2 * 11 * 17)
cos (B) = (121 + 289 -144) / (374)
cos (B) = 266 / 374
cos (B) =
