What are the coordinates of the image produced by applying the composition rx°RO.90°to(-4,3) A. (4,0)
B. (-3, 4)
C. (0, 3)
D. (3, 4)

Also could someone explain how u got the answer, I’m having a hard time understanding this subject.
THANK YOU!!!

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?

What expression is equivalent to (2x-1)(x-3)?

Drag the tiles to the correct boxes to complete the pairs. using the properties of integer exponents, match each expression with the correct equivalent expression.
