Answer:
1/2
Step-by-step explanation:
The "Pythagorean relation" between trig functions can be used to find the sine.
<h3>Pythagorean relation</h3>
The relation between sine and cosine is the identity ...
sin(x)² +cos(x)² = 1
This can be solved for sin(x) in terms of cos(x):
sin(x) = √(1 -cos(x)²)
<h3>Application</h3>
For the present case, using the given cosine value, we find ...
sin(x) = √(1 -(√3/2)²) = √(1 -3/4) = √(1/4)
sin(x) = 1/2

<em>Additional comment</em>
The sine and cosine of an angle are the y and x coordinates (respectively) of the corresponding point on the unit circle. The right triangle with these legs will satisfy the Pythagorean theorem with ...
sin(x)² + cos(x)² = 1 . . . . . . where 1 is the hypotenuse (radius of unit circle)
A calculator can always be used to verify the result.
Answer:
The correct option is;
Yes, the line should be perpendicular to one of the rectangular faces
Step-by-step explanation:
The given information are;
A triangular prism lying on a rectangular base and a line drawn along the slant height
A perpendicular bisector should therefore be perpendicular with reference to the base of the triangular prism such that the cross section will be congruent to the triangular faces
Therefore Marco is correct and the correct option is yes, the line should be perpendicular to one of the rectangular faces (the face the prism is lying on).
For the following relation the domain would be all of the x coordinates.
D=A. 2,0,4,5
Answer:
b
Step-by-step explanation:
Answer: option (b)
1 billion = 1, 000, 000, 000
In scientific notation, a number is rewritten as a simple decimal multiplied by 10 raised to some power n.
10 =101
100= 102
1, 000 = 103
1, 0000 = 104.
..............
Therfore 1 billion can be written as
1 billion =1, 000, 000, 000=10^{9}
Then 1.5 billion = 1.54 10^{9}
Hence option (b) is the correct answer
please give me brilliant answer
thank you
#1 is the third one down (x+3)^2 + (y-2)^2 = 9
