Someone please help. find the angle between the given vectors to the nearest tenth of a degree

u=<-5,-4>, v=<-4,-3>

a: -9.1
b: 1.8
c: 0.9
d: 11.8

What is the range for 31,39,29,34,37,24,36,33,34,28

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4

|2x - 6| > 10 {x|x < -8 or x > 2} {x|x < -2 or x > 8} {x|-2 < x < 8}
