which set of ordered pairs represents a function? {(1, -9), (-5, -5), (1, -8), (-9, 5)}, { (3,6), (2, 1), (-8, 4), (2,0) }
Bezzdna [24]
Answer:
the answer is ((3,6),(2,1),(-8,4),(2,0)) because to be function the domin must not be the same
Answer:
B. The statement is false. This is true only if θ is an acute angle in a right triangle.
Step-by-step explanation:
Trigonometric ratio formula can only be applied to define the relationship between the angles of a right triangle and its side lengths.
Therefore, it is impossible to define or find the tan θ of "any triangle". It only applies to right angled triangles.
In the case of a right triangle, given a reference angle, θ, tan θ = side lenght opposite to θ ÷ side lenght adjacent to θ (tan θ =
.
A right triangle has two acute angles and 1 right angle that which is 90°.
Therefore, we can conclude that:
"B. The statement is false. This is true only if θ is an acute angle in a right triangle."
