Tan x = opp/adj
For angle C, opp = 4, and 3 = adj, so
tan C = 4/3
Answer: False
20 tulips. 2/3=20/30 when you multiply both the denominator and numerator by 10.
T(1) = 3, t(n) = -2t(n-1) + 1
So t(2) = -2(t(1)) + 1 = -2(3) + 1 = -5
t(3) = -2(t(2)) +1 = -2(-5) +1 = 11
t(4) = -2(t(3)) +1 = -2(11) +1 = -21
t(5) = -2(t(4)) +1 = -2(-21) +1 = 43
