Find the volume of the prism. Write your answer as a fraction.
V= cm3

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?

How can (square root of 25) ^2 be rewritten?

How can you find the magnitude of a vector, v = < x,y > , where the horizontal change is x and the vertical change is y?
