Question

Given the vectors s= (7, -5) and t= (4, 6), find 3s and s+t.Write your answers in component form.3s =X(0-0)s+t= 0.15?

Answer 1

`\begin{gathered} 3S\text{ = 3(7,-5) = (3}\cdot7,3\cdot(-5)\text{) = (21,-15)} \\ S+T\text{ = (s1+t1,s2+t2)} \\ S+T\text{ = (7+4,-5+6)} \\ S+T\text{ = (11,1)} \end{gathered}`
