The cosine of an angle is equal to the adjacent side divided
by the hypotenuse. In a right triangle, the hypotenuse is the longest side. Its
value is 13. It also follows that B is the adjacent side.
To solve for B,
B = 13 cos 22.6˚ = 12
The tangent of the angle is equal to the opposite side
divided by the adjacent side. Since B is known, therefore the answer is
tan(22.6˚<span>) = a/12<span> </span></span>
Answer:
range of f(x) = [-4, -2) ∪ [2, 8)
a+b+c+d = -4
Step-by-step explanation:
The graph is attached. The range is the vertical extent of the function. It is defined at f(0) = -4 and f(2) = 2.
The limits f(2-) and f(4-) are -2 and 8, respectively, so the graph has open circles there. These are the ends of the two half-open intervals that make up the range of the function.
The portion of the graph in the domain [4, 7) is included in the range [2, 8), so no special treatment is needed for that piece of the function.
D the argument is not valid because the conclusion does not follow from the premises
I think it is B (don't take me for certain cuz I don't know)
Im pretty sure D bonded pair of electrons is the answer
