The answer would be 679 :)
Yes because she would atlest have 5 wrong but what counts is that she answered most of the questions
If 180° < <em>θ</em> < 270°, then 90° < <em>θ</em>/2 < 135°, which places <em>θ</em>/2 in the second quadrant so that sin(<em>θ</em>/2) > 0 and cos(<em>θ</em>/2) < 0.
Recall that
cos²(<em>θ</em>/2) = (1 + cos(<em>θ</em>))/2
==> cos(<em>θ</em>/2) = -√[(1 + (-15/17))/2] = -1/√17
and
sin²(<em>θ</em>/2) = (1 - cos(<em>θ</em>))/2
==> sin(<em>θ</em>/2) = +√[(1 - (-15/17))/2] = 4/√17
Then
tan(<em>θ</em>/2) = sin(<em>θ</em>/2) / cos(<em>θ</em>/2)
… = (4/√17) / (-1/√17)
… = -4
Answer:
-5
Step-by-step explanation:
Make:
(-5)³ = (-5)×(-5)×(-5) = 25×(-5) = -125
Answer:
Step-by-step explanation:
add 8 to both side
so it is -1/4n>28
so we know that the denominator of 28 is 1
so multiply -1 by 1 and 4n by 28
It will look like this:
-1>112n
then divide both side by 112
the answer is n<-1/112 or 0.0089285
