The given function is A(t)=1512t28.9

Strontium-90 (Sr) is a by-product of nuclear fission with a half-life of approximately 28.9 yr. After the Chernobyl nuclear reactor accident in 1986, large areas 1 28.9 gives the amount 4 (1)- surrounding the site were contaminated with 90Sr. If 15 µg (micrograms) of Sr is present in a sample, the function 4 (t)=15 (in µg) present after t years. Evaluate the function for the given values of t and interpret the meaning in context. Round to 3 decimal places if necessary. (a) 4 (86.7) (b) 4 (231.2) (c) 4 (289) Part: 0/3 Part 1 of 3 (a) 4 (86.7) - After years, approximately ug of Sr remains.
