Answer:
yes it is
Step-by-step explanation:
Answer:
{-3, 3}
Step-by-step explanation:
x^2 - 9 = 0 can be written in factored form as (x -3)(x + 3) = 0. Letting each factor equal zero separately and solving for x, we get x: {-3, 3}
Answer:
A.
Step-by-step explanation:
they both have the same interquartile range so it’s A.
Answer:
The correct answer is option C. Cos x
Step-by-step explanation:
<u>Points to remember</u>
<u>Trigonometric ratios
</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see that, a right triangle with angles and sides are given.
<u>To check the options</u>
1) Sin x = Opposite side/Hypotenuse = p/q
2). Cos y = Adjacent side/Hypotenuse =p/q
3). cos x= Adjacent side/Hypotenuse = r/q
4). tan y = Opposite side/Adjacent side = r/p
Therefore the correct answer is option C. Cos x
