4) (a) For these problems, you should take time to familiarize yourself with common fractions that appear on the unit circle.  \frac{\sqrt{3}} {3} does not appear in the unit circle unless you take the quotient 1/2 divided by sqrt(3)/2 which gives you 1/sqrt(3) which is the same as sqrt(3)/3.  So our numerator is 1/2 and our denominator is sqrt(3)/2.

And remember tangent is just sin/cos.  So what degree has sinx as 1/2 and and cosx as sqrt(3)/2?  Well, 30 degrees does, but 30 degrees is not within the range we are given.  That means they are looking for a sinx that gives us -1/2 and a cosx that gives us -sqrt(3)/2 and that is 210 degrees.

And 210 degrees in radians is 7pi/6.

I hoped that made sense.

(b) This is a lot easier. What angle gives us a cos x of -sqrt(3)/2?  According to the unit circle, 150 degrees and 210 degrees does.  They usually want these in radians, so the answer is 5pi/6 and 7pi/6, respectively.

5) What quadrant is radian measure 5 in?

Well 2pi or roughly 6.28 is a full circle. And 5 is slightly less than 6.28, so it is probably in quadrant IV.

But to be sure let's change 5 radian to degrees:

5 * 180/pi = 900/pi = 286.48 degrees

286.48 degrees is definitely in Q4, so we are correct.

It is believed that the average amount of money spent per U.S. household per week on food is about $98, with standard deviation
il63 [147K]

Answer:

yes, we can reject the hypothesis

Step-by-step explanation:

The null hypothesis  

H0 = mean weekly food budget for all households in this community is $98

Let´s find z

z= (x – mean) / standard deviation / √sample size

z = (100 – 98) / 10 / √100

z = 2

Using  a Z table we can find probability  

P (z>2) = 0.0228

Since P < α , results are significant and we can reject the hypothesis

Solve for m<br><img src="https://tex.z-dn.net/?f=g%20%3D%204cm%20-%203m" id="TexFormula1" title="g = 4cm - 3m" alt="g = 4cm - 3m

This is what is called a literal equation.  Solve it for m just like you would solve any equation for x.  Isolate the term with the variable you're looking for.  Do this by subtracting 4cm from both sides to give you g - 4cm = -3m.  Now we need to divide by -3 to get m alone: \frac{g-4cm}{-3}=m.  Or we could lose the negative on the 3 in the denominator like this: \frac{-g+4cm}{3}=m and \frac{4cm-g}{3}=m.  There you go!  Any one of those last three would work.  It just depends upon how your teacher wants you to express your answer.
