Answer:
B. 0.635
Step-by-step explanation:
Having a percent means its out of 100 so we can turn the percent into a fraction. 63.5/100
We cant have a decimal in our fraction, so we can multiply by 10 to get rid of it. (63.5*10)/(100*10)=635/1000
Since the denominator is a multiply of 10, we can convert the numerator into a decimal. .635
So your answer would be B. 0.635
Sine and Cosine are defined over every real number, really over every complex number if you want to go there. So the answer is never.
Pardon me but this seems like a slightly confused question.
When we talk about sinθ , the θ is an angle. θ is just a real number that’s used in the common parameterization of the unit circle,
(x,y)=(cosθ,sinθ)
θ is interpreted as the angle between two rays, one the positive x axis, and one the ray originating at the origin and intersecting the unit circle at (x,y). The angle is given by the arc length of the unit circle cut by the two rays.
There are other ways to parameterize the circle, the most important being
(x,y)=(1−t21+t2,2t1+t2)
which is on the unit circle because of the easily verifiable identity known to Euclid, (1−t2)2+(2t)2=(1+t2)2
The parameterization is defined for all real t but doesn’t quite get the entire unit circle. It’s missing (−1,0). We can allow t=∞ , essentially treating t as a projective parameter, a ratio, and get the entire circle.
Answer:
4
Step-by-step explanation:
8x + 4 = 27 + 6x - 15
Combine Like Terms:
8x + 4 = 12 + 6x
Combine Like Terms:
2x = 8
Combine Like Terms:
X = 4
The answer is 14 + x = 17
