238. "Pu is used to make thermoelectric power sources for spacecraft. Suppose that a space probe was launched in 2012 with 3.0 The isotope of plutonium Part 1 of 2 238. Pu is 87.7 yr, write a function of the form O (t) = 0,e (a) If the half-life of –kt to model the quantity O (t) of 238 Pu left after t years. Round the value of k to five decimal places. Do not round intermediate calculations. O (1) = e Part: 1/ 2 Part 2 of 2 238 Pu is required to power the spacecraft's data transmitter, for how long after launch would scientists be able to receive data? Round to (b) If 1.8 kg of the nearest year. Do not round intermediate calculations, Scientists will be able to receive data for approximately yr.
