$\\ \rm\Rrightarrow -42z^2=14z$

$\\ \rm\Rrightarrow 42z^2=-14z$

$\\ \rm\Rrightarrow 3z^2=-z$

$\\ \rm\Rrightarrow 3z=-1$

$\\ \rm\Rrightarrow z=-1/3$

Another root is 0

A point in rectangular coordinates is given. Convert the point to polar coordinates. Round your answers to two decimal places.

postnew [5]

Answer:

(√74, 54.46°)

Step-by-step explanation:

The rectangular coordinate point is given as; (5, 7)

Now, converting rectangular coordinates to polar coordinates is done by;

(r, θ)

Where, r is the magnitude while θ is the angle

r = √(5² + 7²)

r = √74

tan θ = (7/5)

θ = tan^(-1) 1.4

θ = 54.46°

Thus,polar coordinate is; (√74, 54.46°)
