Vector u has a magnitude of 5 units, and vector v has a magnitude of 4 units. which of these values are possible for the magnitude of u + v?

Remember the triangular inequality says that if u and v are vectors then

Since the magnitude always is a nonnegative number and the magnitude of u is 5 units and the magnitude of v is 4 units ,

Then possibles values for the magnitude of u +v  are in the interval

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
