Find the unit vector in the direction of u = (-3,2). a. u = -3√13 / 13i + 2√13 / 13j b. u = -3√5 / 5i + 2√5 / 5j c. u = 3√5 / 5i - 2√5 / 5j d. u = 3√13 / 13i + 2√13 / 13j

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
