Answer:
D is correct option.
Step-by-step explanation:
We are given a function 
We need to find new function reflection of f(x) across the y-axis.
When function reflection across y-axis 
Therefore, 
New function, 
Thus, D is correct option.
Answer:
-2
Step-by-step explanation:
x = r cos θ
y = r sin θ
dx/dθ = -r sin θ + r' cos θ
dy/dθ = r cos θ + r' sin θ
dy/dx = (r cos θ + r' sin θ) / (-r sin θ + r' cos θ)
At θ = π/2, cos θ = 0, sin θ = 1, and r = 1. So the derivative simplifies to:
dy/dx = (r') / (-1)
dy/dx = -r'
dy/dx = -2 sin θ
dy/dx = -2
Answer:
AAA (angle-angle-angle) similarity theorem
Step-by-step explanation:
The two given triangles PSR and XYZ, are similar.
And all their angles are also similar.
We can conclude, that both are similar based on AAA similarity theorem.
The AAA (angle-angle-angle) similarity theorem states that two triangles have their corresponding angles equal, if and only if their corresponding sides are proportional.
XZ is proportional to SR. XY is proportional to SP and YZ is proportional to PR.
