Let (s n ) be a sequence in r. (a) prove lim s n = 0 if and only if lim |s n | = 0. (b) observe that if s n = (−1) n , then lim |s n | exists, but lim s n does not exist.

Choose the correct slope of the line that passes through the points (1, -3) and (3, -5)

Which of these triangle pairs can be mapped to each other using two reflections?

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
