6. Triangle CDE with vertices C(-2,-2), D(1,-4), and E(-3,-4): a) dilation with scale factor of 4 centered (-1.-3)

b) reflection in the line y = -x

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?

Write the expression as a single natural logarithm. 2 in a - 4 in y
