Answer:
220 color combinations are possible.
Step-by-step explanation:
A combination is a way of selecting members from a grouping, such that the order of selection does not matter.
in our case we have 3-combinations of a set of 12 elements:
C(12, 3) = 12!/(3! (12-3)!)
C(12, 3) = 12!/(3! 9!)
C(12, 3) = (10*11*12)/(2*3)
C(12, 3) = 220 color combinations are possible.
I think it’s B but I’m not for sure
sine:<span> the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
</span>cosine: the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
tangent: <span>a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.</span>
The formula is
.. A = (1/2)ab*sin(C)
.. = (1/2)(8 m)(12 m)sin(51°)
area ≈ 37.3 m^2
Answer:
1.732i (complex form)
its weird, at high-school level complex shouldn't come, its considered mistake in the question. But the mathematically its all correct
