What are the coordinates of D' after its preimage, D(4, -8), is reflected over the line y = x?

1 answer:

6 0

Answer: D' is (-8,4)

Step-by-step explanation: The rule for reflection y=x is (x,y)>( y,x) So when relecting over the axis y=x the x cordinate and the y cordinate switch places.

Find the general solution for cos x = 0, where n is an integer.

Romashka-Z-Leto [24]

First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2

Now, this is the answer for angles between 0 and 2pi

but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:

x = pi/2 + n*pi

here n is any integer.
