Step-by-step explanation:
5% = 0.05
0.05 * 35 = 1.75

18.10 = 18.1
6,324.50 = 6,324.5
By applying Pythagorean theorem, we have proven that the point (-1/2, -√3/2) lies on the unit circle.
<h3>How to prove this point lies on the unit circle?</h3>
In Trigonometry, an angle with a magnitude of -120° is found in the third quarter and as such, both x and y would be negative. Also, we would calculate the reference angle for θ in third quarter as follows:
Reference angle = 180 - θ
Reference angle = 180 - 120
Reference angle = 60°.
For the coordinates, we have:
sin(-120) = -sin(60) = -1/2.
cos(-120) = -cos(60) = -√3/2.
By applying Pythagorean theorem, we have:
z² = x² + y²
z = √((-1/2)² + (-√3/2)²)
z = √(1/4 + 3/4)
z = √1
z = 1.

Answer:
Option C is false.
Step-by-step explanation:
A. We are given; 0.7 < 4/5
Now, 4/5 in decimal form is written as 0.8.
Thus,0.7 is less than 0.8. So statement is true.
B) We are given: 2/3 > 0.34
Now, 2/3 in decimal form is written as 0.67.
Thus,0.67 is greater than 0.34, so statement is true.
C) We are given: 2.26 > 214
214 is obviously greater than 2.26. Thus statement is false.
D) We are given: 35/6 > 37/8
Now, 35/6 in decimal form is written as 5.83.
Likewise, 37/8 is written in decimal form as 4.63
Thus,5.83 is greater than 4.63, so statement is true.
Finally, the only false one is Option C
Answer:
18 m/s
Step-by-step explanation:
We used the given expression for the wind power: 
replacing the power (on the left hand side of the equal sign) by 15.83 MegaWatts, and then solve for v which is raised to the power 3:
![P(v)=0.002713v^3\\15.83=0.002713v^3\\\frac{15.83}{0.002713} =v^3\\v^3=5834.87\\v=\sqrt[3]{5834.87} =18.003\frac{m}{s}](https://tex.z-dn.net/?f=P%28v%29%3D0.002713v%5E3%5C%5C15.83%3D0.002713v%5E3%5C%5C%5Cfrac%7B15.83%7D%7B0.002713%7D%20%3Dv%5E3%5C%5Cv%5E3%3D5834.87%5C%5Cv%3D%5Csqrt%5B3%5D%7B5834.87%7D%20%3D18.003%5Cfrac%7Bm%7D%7Bs%7D)
