Answer:

-In mathematics, the argument is a multi-valued function operating on the nonzero complex numbers. With complex number z visualized as a point in the complex plane, the argument of z is the angle between the positive real axis and the line joining the point to the origin, shown as φ in figure 1 and denoted arg z. To define a single-valued function, the principal value of the argument (sometimes denoted Arg z) is used. It is chosen to be the unique value of the argument that lies within the interval (–π, π].

A vector has an x-component of −24.5 units and a y-component of 31.5 units. Find the magnitude and direction of the vector.

jasenka [17]

we are given a vector

whose

x-component is -24.5

so, $v_x=-24.5$

y-component is 31.5

so, $v_y=31.5$

Magnitude:

we can use formula

$|v|=\sqrt{(v_x)^2+(v_y)^2}$

we can plug values

$|v|=\sqrt{(-24.5)^2+(31.5)^2}$

$|v|=39.90614$

Direction:

we can use direction formula

$\theta=tan^{-1}(\frac{v_y}{v_x})$

now, we can plug values

$\theta=tan^{-1}(\frac{31.5}{-24.5})$

$\theta=180-52.12$

$\theta=127.88$ ................Answer
