Answer: π radians
2. Solve for y: 3 y+1 = 9 y−1.
1. 1 3. 3
2. 2 4. 4
3. Use the formula: A = Pert, where ‘e’ = 2.718, to
model the decay of radioactive material. A certain
radioactive material decays at a rate of 1.2% daily. At
the end of one week, there were 110.333 grams of
radioactive material left in a sample. How many grams
were there at the beginning of the week? Round
your answer to the nearest whole number.
Answer: grams
4. Solve the equation for ‘x’.
5. Solve for the positive value of x, to the nearest
tenth: 1. x = 2. x = 2
3. x = 3
4. x = Answer: x =
