41. What is the image of O(- 3, - 2) after two reflections, first across the line y = - 5 , then across the line x = 1 ? (1 poin

liberstina [14]

Answer:

D(5,-8)

Step-by-step explanation:

The given point is (-3,-2)

When we reflect in the line y=k, we use the rule (x, 2k-y)

This implies that:

$(-3, - 2)\to (-3, 2*-5--2)$

$(-3, - 2)\to (-3, - 8)$

When we reflect in the line x=k, we use the rule

$(x,y)\to (2k-x,y)$

Now we have x=1

This implies that:

$( - 3, - 8)\to (2 \times 1- - 3, - 8)$

$( - 3, - 8)\to (5, - 8)$

Sin(θ) cos(3θ) + cos(θ) sin(3θ) = 0

pychu [463]

$\displaystyle\\
\text{We use formula:}\\
\sin(\alpha+\beta)=\sin(\alpha)\cos(\beta)+cos(\alpha)\sin(\beta)\\\\
Resolve:\\\\
\sin(\Theta)cos(3\Theta)+cos(\Theta)sin(3\Theta)=0\\\\
\sin(\Theta+3\Theta)=0\\\\
\sin(4\Theta)=0\\\\
\text{We have two solutions:}\\\\
4\Theta=0~~\Longrightarrow~~\Theta=\frac{0}{4}=0~~\Longrightarrow~~ \boxed{\Theta_1=0+2k\pi}\\\\
4\Theta=\pi~~\Longrightarrow~~\Theta=\frac{\pi}{4}~~\Longrightarrow~~ \boxed{\Theta_2=\frac{\pi}{4}+2k\pi}\\\\$
