This test is marked as 2012 so it is reasonable for me to assume that it is a practice test.

So I do not mind answering.  :)

I always enjoyed your funny posts Rosala.      

\(\sin(\theta) < 0 \mbox{ and }\cos(\theta)>0\)

\(\sin(\theta) = -\dfrac 2 5 \Rightarrow \cos(\theta) = \pm \sqrt{1-\sin^2(\theta)}\\ \mbox{We know }\cos(\theta)>0 \mbox{ so we select the positive value.}\\ \cos(\theta) = \sqrt{1-\dfrac{4}{25}} = \dfrac{\sqrt{21}}{5}\)

\(\sec(\theta)=\dfrac 1 {\cos(\theta)} = \dfrac {5}{\sqrt{21}}= \dfrac{5\sqrt{21}}{21}\)

Humans eat it too.  :)

OK. We had some problems opening your pdf file. But, unfortunately for you, we may not be able to answer your "Exam Questions", because it maybe illegal to do so, because it may constitute as "cheating".  However, Melody or somebody else may be able to tell you for sure. Just keep an eye on this site until you hear from one of the Moderators.

Simplify the following:
(8+6/11)/(10/11)

Multiply the numerator of (8+6/11)/(10/11) by the reciprocal of the denominator. (8+6/11)/(10/11) = ((8+6/11)×11)/(10):
((8+6/11)×11)/(10)

Put 8+6/11 over the common denominator 11. 8+6/11  =  (11×8)/11+6/11:
((11×8)/11+6/11 11)/(10)

11×8  =  88:
((88/11+6/11)×11)/(10)

88/11+6/11  =  (88+6)/11:
((88+6)/11×11)/(10)

| 1 |
| 8 | 8
+ |  | 6
| 9 | 4:
(94/11×11)/10

94/11×11 = (94×11)/11:
(94×11)/11/10

((94×11)/11)/10 = (94×11)/(11×10):
(94×11)/(11×10)

(94×11)/(11×10) = 11/11×94/10 = 94/10:
94/10

The gcd of 94 and 10 is 2, so 94/10 = (2×47)/(2×5) = 2/2×47/5 = 47/5:

I don't quite understand what you nean by "fraction picture"? You may want to use this online fraction calculator, which I find to be pretty good:http://www.calculatorsoup.com/calculators/math/fractions.php

Learn how to use the calculator here. Enter your number first. Then press the key "x^2", then the = sign. That should give you your answer.

Enter your number first. See the word "Log"? Just under it, there is a little arrow. Click on it and you will see "ln". Click on ln and then = sign, which should give you your answer.

Why is b***s considered a swear word?

what is 1/5 of 340?=1/5 X 340=340/5=68

150/10 =15

what is 1/10 of 150?=1/10 X 150=150/10=15

  Find the reference angle of 158 degree=22°

   Find the reference angle of 9pi/4= pi/4 radians        

Evaluate CSC 3pi/2=-1 in radians

 Evaluate COS 3pi/2=0.9966....in degrees

Evaluate CSC 3pi/2=12.17226 in degrees.

A bunch of software engineers in Germany, I think!.

Evaluate COS 3pi/2=0 radians

    (0.6-10m)(8)=4.8 - 80 m

MOO????

Well, were waiting!!!
