Recall the double angle identity for cosine:
It follows that
Since 0° < 22° < 90°, we know that sin(22°) must be positive, so csc(22°) is also positive. Let x = 22°; then the closest answer would be C,
but the problem is that none of these claims are true; cot(32°) ≠ 4/3, cos(44°) ≠ 5/13, and csc(22°) ≠ √13/2...
Answer:
32
Step-by-step explanation:
Answer:
y=-4x+7/2
Step-by-step explanation:
slope-intercept form follows the following format:
y=mx+b
simply replace m with -4 and b with 7/2
Answer:
13x + 7 + 4x + 15 = 90
17x + 22 = 90
17x = 68
x = 4
4(4) + 15= 16 + 15= 31
13(4) + 7 = 52 + 7 = 59
Step-by-step explanation:
Step-by-step explanation:
sin(x) = M, M > 0
= sin(x - π)
= sin(x)cos(π) - cos(x)sin(π)
= sin(x).(-1) - cos(x).0
= -sin(x) - 0
= -sin(x)
= -M
