over the week the daily low temputures in degrees Fahrenheit have been -4, 6.2, 18 1/2, -5.9, 21, -1/4, and 1.75. list these numbers in order from least to greatest
we have that
1/2=0.5
1/4=0.25
so
order from least to greatest
<h2>-5.9,-4,-1/4,1/2,1.75,6.2,18,21</h2>
Answer:
The bottom one ....see below
Step-by-step explanation:
Using reference angle of pi/8 and half angle trig identity:
cos ( angle/2) = -sqrt (1 + cos (angle) /2)
cos ( pi/4 / 2) = - sqrt (1+ cos ( pi/4)/2)
<u> cos (pi/8)</u> = - sqrt (1 + sqrt (2) / 2)
= - sqrt (1 + sqrt 2) / sqrt 2 rationalize the denominator
= - sqrt ( sqrt 2 + 2) / 2
re arrange to
- sqrt ( 2 + sqrt2) / 2 the fourth answer
3+6, I believe. (I have to explain it a little better, so, 9-6=3, which means that 3+6=9)
A is (-3,-1) B is (3,-1) C is (-1,3)
