“A” is the answer; “B” is not correct/equivalent to the given equation, “C” is not simplified enough, and “D” is in slope-intercept form
2 or 3 I think is the answer for number 5
The solution to the problem is as follows:
<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA
and
sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA
Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS

Answer:
d) 0.4
Step-by-step explanation:
P(Ra) = 0.998
P(Rb) = 0.995
P(A) = 0.4
P(B) = 0.6
The probability that method A was performed, given that the eye was recovered within a month of the surgery, is determined by the probability that the eye recovered within a month with method A (P(A) x P(Ra)),divided by the probability that the eye recovered within a month with either method (P(A) x P(Ra) + P(B) x P(Rb)):
The probability that method A was performed is 0.40.
