Answer:
- B. Ry-axis(x, y) → (–x, y)
Step-by-step explanation:
<u>As per the graph we see that:</u>
- Reflection over y-axis, y- coordinates remain as is, x- coordinates change to opposite
<u>So the rule is:</u>
- Ry-axis (x, y) → ( - x, y)
Correct option is B
Answer:
<h2>rise = 6</h2>
Step-by-step explanation:
Xavier wants to earn more then 575 dollars a week, he will have to sale x<3,600 a week . So the answer is C
The average is 80*
80* + 80*=160 divided by 2 is 80*
Begin with cos(θ) = 5/13, θ in Quadrant IV
you should distinguish the 5-12-13 right-angled triangle
and then cosØ = adjacent/hypotenuse
x = 5, r = 13 , y = -12, since Ø is in IV
and sinØ = -12/13
also tan(ϕ) = −√15 = -√15/1 = y/x and ϕ is in II,
y = √15 , x = -1
r^2 = x^2 + y^2 = 15+1 = 16
r = 4
sinϕ = √15/4 , cosϕ = -1/4
you must know that:
cos(θ − ϕ) = cosθcosϕ + sinθsinϕ
= (5/13)(-1/4) + (-12/13)(√15/4)
= -5/52 - 12√15/52
= (-5-12√15)/52
