Consider the interval [-16, 14]. (a) Find the length of the interval. 30 (b) If we partition [-16, 14] into 10 subintervals of equal length, then (i) the length of each subinterval is 3 (ii) the first subinterval is [-16, -13] . (Enter your answer using interval notation.) (iii) the midpoint of the first subinterval is -14.5 x Your answer must be a reduced fraction or integer.. (iv) the midpoint of the second subinterval is -11.5 x Your answer must be a reduced fraction or integer..
