cos^-1(.4685) = 62 degrees
angle L = 180-90-62 = 28 degrees
Answer:
The function operation is 0
The composite function is -1
Step-by-step explanation:
Answer:
y = a + 2b + 3c
y = 4+ 2(7) + 3(2)
y = 4 + 14 + 6
y = 24
Step-by-step explanation:
3(d+2)-12 = d-2
3d +6 -12 = d - 2
3d-d = 12 - 6 - 2
2d = 4
d = 2
