Determine the magnitude of the sum of the two vectors: 2.5i+1.8j; - 6i-0.7j

A. 3.67

Step-by-step explanation:

1. Add the two vectors (2.5,1.8) + (-6,-.7) = (-3.5,1.1)

2. Find the magnitude using square root of a^2+b^2

sqrt (-3.5) ^2 + (1.1^2) = sqrt (12.25+1.21) = sqrt (13) = 3.67

Answer for this question would be: A, 3.67
