Fractional index means "xth root of". Negative index means a fraction. So together, what it really means is:

$\frac{1}{\sqrt[5]{32}} = \frac{1}{2}.$

Vector V is in standard position and makes an angle of 50° with the positive x-axis. Its magnitude is 15. Write V in component f

Scilla [17]

Answer:

a=9.641, b=11.49

Vector will be 9.641 i + 11.49 j

Step-by-step explanation:

We have given that vector V has the magnitude of 15

And it makes an angle of 50 $^{\circ}$ with positive x axis

Now let the x component of vector V is a and y component of vector V is b

So $a=Vcos\Theta =15\times cos50^{\circ}=9.641$

$b=Vsin\Theta =15\times sin50^{\circ}=11.49$

In vector form 9.641 i+11.49 j
