Let u= < 4,3> . find the unit vector in the direction of u, and write your answer in component form.

The component form of the unit vector in the direction of u will be:

 and this can be determine by using the unit vector formula.

Given :

u = <4,3>

Unit vector formula will be use to determine the unit vector in the direction of u, that is:

    ----- (1)

So, the magnitude of u will be:

Now, put the value of and  in equation (1).

So, the component form of the unit vector in the direction of u will be:

correct me if i am wrong.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
