Let u1 = (1, 1, 2, 2), u2 = (2, 3, 5, 6), and u3 = (2, −1, 3, 6). use matlab to write the vector as a linear combination of the vectors u1, u2, and u3.
(a) v = (0, 5, 3, 0)

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
