I need some help with this problem

1. A team of biologists asks you to approximate the population of bacteria growing in agar after 1 day. . They've seeded this population with 5 bacteria. . After 1 hour, they've counted a total of 15 bacteria. . After 2 hours, they've counted a total of 10 bacteria. . After 3 hours, they've counted a total of 110 bacteria. Wikipedia reports that populations of this type abide by the equation Population = Cek time So you'd like to find C and & that best fit this data, then for that C and k evaluate Ce21. Find a 1 x 2 matrix A and a 4-dimensional vector b, with the property that, for a and y numbers solving the matrix equation then et = C and y ~ k are approximate solutions to C and k. A = b=
