Give the component form of the resultant vector in the following.
u = (10, 5)
-3u = ?
To find the component form of -3u, we first need to find the component form of u. Looking at the given information, u = (10, 5).
The component form of a vector represents its x and y components. In this case, the x component of u is 10 and the y component is 5.
To find -3u, we need to multiply each component of u by -3. Multiplying the x component of u by -3, we get:
-3 * 10 = -30
Similarly, multiplying the y component of u by -3, we get:
-3 * 5 = -15
Therefore, the component form of -3u is (-30, -15).
