\f\fThe differential equation dy +x3 = 0 is solved by y = - 35-2 + C. O true O falsedy =z If i, what is the value of the slope field at the point (3, -1)? O -3 O It cannot be determined from the given information. Oo 3 If = 2y - 3x, and it goes through the point (2, 1), if you tried to estimate the y-value at x = 2.3 using Euler's Method, where Ax = 0.3, you would get a y-value of -0.2. O false O trueThe Half-Life of a 1000 gram substance is 50 years. If it decays according to an exponential growth model, the amount of time it will take for the substance to be only 100 g, is O Between 150 and 155 years (O Between 165 and 170 years O Between 160 and 165 years O Between 155 and 160 years
