Answer and Step-by-step explanation:
Given Asin(wt + phi), we know that sin (A + B) = sinAcosB + sinBcosA. This means:
Asin(wt + phi) = Asin(wt)cos(phi) + Asin(phi)cos(wt).
Let Acos(phi) = c2 and Asin(phi) = c1 we have:
Asin(wt + phi) = c2sin(wt) + c1cos(wt)
Answer:
-4x + 9
Step-by-step explanation:
(-2,15)(9,-18)
slope = (-18 - 15) / (9 - (-2) = -33/11 = -3
There can be 2 answers to this question....
point slope form : y - y1 = m(x - x1)
(1) using points (-2,15)...
y - 15 = -3(x + 2) <== one possible answer
(2) using points (9,-18)
y + 18 = -3(x - 9) <== another possible answer
Angle: 180-132 = 48
180-48= 132
132/6=22
2(22)= 44
4(22)= 88
44+88+32 = 180
Answer:
Measure of angle < CBA = 88
Measure of angle < BCA = 44
