1. ### Find the unit vector for v = -6i +5j?

v = -6i + 5j ||v|| = | -6i + 5j | = √[(-6)² + (5)²] = √61 Unit vector = v / ||v|| = (-6i + 5j) / √61 or (-6/√61)i + (5/√61)j Hope this helps! J

3. ### how to solve this problem for v?

cross multiply you get -3v(v∧2-4v+4) = -24(v-2) divide both sides by -3 ==> v(v∧2-4v+4) = 8(v-2) ==> v^3 - 4v^2 +4v = 8v - 16 ==>v^3 - 4v^2 +4v - 8v +16 = 0 ==> v^3 - 4v^2 - 4v +16 = 0 now solve using calculator or factor theorem let f(v...

4. ### Find each quantity if v= 3i-5j and w=-2i+3j?

||v|| = √((3)² + (-5)²) = √(9 + 25) = √34 ||w|| = √((-2)² + (3)²) = √(4 + 9) = √13 ||v|| - ||w|| = √34 - √13 ≈ 2.2254

5. ### Find ||v||-||w||, If v= -3i-3j and W= -5i-5j?

||v|| = sqrt(x^2 + y^2). Square the x and y components. Add. Take the square root. Do the same with w to get ||w||. ||v|| - ||w|| means take the value of ||v| and the value of ||w|| and subtract. "...
