Correct question is;
The terminal side of angle θ intersects the unit circle in the first quadrant at (9/25,y). What are the exact values of sinθ and cosθ?
Answer:
sinθ = (√544)/25) and cosθ = 9/25
Step-by-step explanation:
We are given that (9/25,y) lies on the unit circle. Thus, from general representation of equation of a circle, we can write that;
(9/25)² + y² = 1²
y² = 1 - (9/25)²
y² = (625 - 81)/25²
y² = 544/25²
y = ±(√544)/25
We are told the point is in the first quadrant and so we will choose the positive value of y = (√544)/25.
Therefore, the terminal side of the angle θ intersects the unit circle at [9/25, (√544)/25)]
In unit circle geometry, cosθ = x, while sinθ = y.
Thus; sinθ = (√544)/25) and cosθ = 9/25
this number can be written as 3+0.242424
Answer:
6x + 3y
Step-by-step explanation:
3x + 3 (x + y) ➡ 3x + 3x + 3y ➡6x + 3y
The answer would be 300829, well how did u get that?
So the thousandth number is 9, or the second nine. And we look at the number right of it which is eight, that is more than five. So then that becomes, a ten, we carry the one, over to the other nine, and that becomes a ten too, so then carry that one again to that two, and two plus one is three, so then the final answer, is 300829. Hope that this would help you!
