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°.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
