The value of the trigonometry are sin(Π-Ɵ) = 0.84 and sin(Π + Ɵ) = -0.84
According to the question, there is a circle whose radius is 1 and the ray intersects the circle at point (0.54, 0.84).
We need to find the trigonometric values, that is
sin(Π-Ɵ) = sin(Ɵ) as we know that when the angle is in third quadrant sin is positive.
sin(Π+Ɵ) = -sin(Ɵ) as we know that when the angle is in fourth quadrant sin is negative.
Also note that, sinƟ = perpendicular/hypotenuse
Perpendicular = 0.84 as the perpendicular length will be equal to the length of the y-axis
Hypotenuse = 1 as the hypotenuse will be the radius of the circle which is formed by the ray.
Thus, sinƟ = 0.84/1 = 0.84
Hence, sin(Π-Ɵ) = 0.84
And sin(Π+Ɵ) = -0.84

Answer:
D: r^2 = 4
Step-by-step explanation:
Square the radius: r^2 = 2^2 = 4 (answer)
First: work out the difference (increase) between the two numbers you are comparing. Increase = New number - Original Number
Then: divide the increase by the original number and multiply the answer by 100. % Increase = Increase ÷ Original Numberｘ100<span>
30 - 22 = 8
8</span> ÷ 22ｘ100 = 36.3636363636
Answer:
Jeff finished first
Step-by-step explanation:
To solve this equation, I can either converts 2 minutes 2 seconds to seconds or convert 121 seconds to minutes
<u><em>CONVERT 2 MINUTES 2 SECONDS TO SECONDS</em></u>
60 seconds = 1 minutes
to convert 2 minutes 2 seconds to seconds, multiply 2 minutes by 60 and then add 2 seconds to it
2 x 60 = 120 seconds
120 seconds + 2 seconds = 122 seconds
Paul finished in 122 seconds while Jeff finished in 121 seconds. Jeff finished first
<u><em>CONVERT 121 SECONDS TO MINUTES</em></u>
60 seconds = 1 minutes
To convert 121 seconds to minutes, we have to divide by 60
121/60 = 2 minutes 1 second
Paul finished the race in 2 minutes 2 seconds while eff finished the race in 2 minutes 1 second. Jeff finished first
