Find the angle between the given vectors to the nearest tenth of a degree. u = < 2, -4> , v = < 3, -8>
3.0°
6.0°
-7.0°
16.0°

Angle between u an v i.e θ is 6°.

Step-by-step explanation:

Given:

To Find:

Angle between u an v i.e θ = ?

Solution:

If u bar and be  v bar are two vectors inclined at an angle θ then their scalar product is defined by,

Substituting the given values we get

Angle between u an v i.e θ is 6°.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
