<span><u>Answer </u>
x = 30</span>°<span> or x = (360 – 30) = 330</span>°<span> for value of (0≤x≥360)
<u>Explanation
</u>
The first step is to find the anti-cosine of √3/2.
cos^(-1)〖√3/2〗=30°
So, x=30°
The values of x can be many so a limit has to be given. For one complete cycle, the values of x would be.
Since cosx is positive the value of x must have been in the first quadrant and the 4th quadrant.
So, x = 30</span>°<span> or x = (360 – 30) = 330</span>°<span>

Answer:
all done bud, I'm just here for the extra points :D
Answer:
D
Step-by-step explanation:
Direct Variation takes the form
Inverse Variation takes the form
- Where A and B are the 2 variables associated and k is the proportionality constant.
<em>Since </em><em>number of dolls [N] </em><em>varies </em><em>directly </em><em>with </em><em>advertising budget [A],</em><em> in our equation, </em><em>A should go in the numerator</em><em> and since </em><em>number of dolls [N] </em><em>varies </em><em>inversely</em><em> with </em><em>price of dolls [P]</em><em>, </em><em>P should go in the denominator.</em>
Thus we can write our equation as:
Solving this equation for k given the information "The company sold 5200 dolls when $26,000 was spent on advertising and the price of a doll was set at $30":
Rounding to
Now, given that we want to find the number of dolls [N] when and , we have:
dolls
Answer choice D is correct.
The answer would be 70 degrees.
In order to find this answer, we must first look at the cos value of an angle. The unknown angle here gives us an adjacent side of 3.4 and a hypotenuse of 10. Thus, we can use the following with cos.
Cos(A) = 3.4/10 or Cos(A) = .34
As a result, we can then use the arccos function to find the answer.
acrcos(.34) = A
70.12 = A
Then when we round, we'd get 70.
