Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
sergiy2304 [10]

Answer:

The measure of angle θ is 7π/6. The measure of its reference angle is  <u>210°</u>

and sin θ is​ <u>-1/2</u>.

Step-by-step explanation:

The correct question is:

<em>The measure of angle θ is 7π/6. The measure of its reference angle is  ___</em>

<em>and sin θ is​ ___</em>

180° is equivalent to π radians. To transform 7π/6 radians to degrees, we have to use the following proportion:

180° / π radians = x° / (7π/6 radians)

x = (180/π) * (7π/6 radians)

x = 210°

And sin(210°) = -1/2

Please help me I have a test tomorrow
yarga [219]

#5 is very nicely and correctly done.

#7 says: "No matter what X may be, this function of it is always 9 more than 1/2 of X .".

That's a very powerful statement. Now you know that if X is ever 2, the function will be 1/2(2)+9 which is 10.

If X is ever zero, the function will be 1/2(0)+9 which is 9. If X is ever a cow, the function will be 1/2 of a cow, plus the number 9. Which makes no sense, but that's what the function says.

So, when X is -8, the function is 1/2 of -8, plus 9. Which is 5 ... the 'f' of -8.

Whatever X happens to be at the moment, just write that number in place of X in the function, and it'll show you the function of what X is.

f(a bazillion) = 1/2(a bazillion) + 9 .

f(a-28) = 1/2(a-28) + 9 (but simplify it)
