If vector u=(5,-7) and v=(-11,3), 2v-6u= and ||2v-6u||≈

In this problem we have two vectors:

So we need to find two things:

and:

FIRST:

In this case we have the multiplication of vectors by scalars. A scalar is a simple number, so:

SECOND:

If we name:

Then, is the magnitude of the vector . Therefore:

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
