Composition. Suppose we want to find the composition of a function with itself. Let g(x) = 5(x+6)2 Then the function(g o g)(x) equals 5(5x2 60X 174) 5(5x2 60X174) 5(x+5)2 5(5x2 60x 174)2 25(x+6)4 5(5x2 60x174)2 25(x+6)4 5(x+5)2 Radioactive Decay. Suppose the volume of a radioactive substance (in kg) follows the exponential decay model Q(t) = Qoe'kt If after 6 years, the volume is 50% of its original size, what is the decay constant k? 4.1589 0.1156 6 12 0.1155 None of the other answers -4.1588 E PP Y additional tool to change the current of the first device to match the current of the second device. a+3x+4x2 ifX
