A six month old puppy weighs x = 7.0 kg. From this age, the puppy will grow such that its weight, x, is described by the following equation: where t is time measured in months. Use the Euler method of integration with a time step of ∆t = 0.1 months to find the puppy's weight at 6.5 months. Enter your answer with at least 4 significant figures. (On the actual exam, you will be asked to show all work and intermediate steps for full credit.)
