Vectors a, b, c are defined as:
a = 2i + 5j; b = i - 3j; c = -3i - j. Answer all correct answers (remember, i = xhat, j = yhat, k = zhat
a + b = 3i + 8j
a - b = i + 8j
a + c = -i + 4j
c - b = -5i + 6j
Vector a = 2i + 3j - 5k. What is the value of 3a?
3i + 3j - 3k
5i + 6j - 8k
6i + 9j -15k
6i + 6j - 15k
