Write out steps on how to solve 21.4divided by 4.75

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

21.4÷4.75

First- you have to move the decimal placement two times to the right
Second- you have to put the number 21.4 under the dividing box
Third- put the number 4.75 out to the left of the decimal box
Fourth- when that's all completed you have to multiply the 475. until you get clos to the number 2140.
Fifth- once done you have to subtract the multiplied number that you get you then subtract it from 2140
Sixth- you keep on doing the fifth step until you get a reasonable answer
Seventh- you write the answer down
Eighth- there is no eighth step so you can stop reading this answer

Find the rectangular coordinates of the point with the polar coordinates ordered pair 7 comma 2 pi divided by 3.

Morgarella [4.7K]

Answer:

$\left(-\dfrac{7}{2},\dfrac{7\sqrt{3}}{2}\right)$ .

Step-by-step explanation:

The given point is

$\left(7,\dfrac{2\pi}{3}\right)$

We need to find the rectangular coordinates of the given point.

If a polar coordinate is $(r,\theta)$ , then

$x=r\cos theta$

$y=r\sin theta$

In the given point $\left(7,\dfrac{2\pi}{3}\right)$ ,

$r=7,\theta=\dfrac{2\pi}{3}$

Now,

$x=7\cos \dfrac{2\pi}{3}$

$x=7\cos \left(\pi-\dfrac{\pi}{3}\right)$

$x=-7\cos \left(\dfrac{\pi}{3}\right)$

$x=-7\left(\dfrac{1}{2}\right)$

$x=-\dfrac{7}{2}$

and,

$y=7\sin \dfrac{2\pi}{3}$

$y=7\sin \left(\pi-\dfrac{\pi}{3}\right)$

$y=7\sin \left(\dfrac{\pi}{3}\right)$

$y=7\left(\dfrac{\sqrt{3}}{2}\right)$

$y=\dfrac{7\sqrt{3}}{2}$

Therefore, the required point is $\left(-\dfrac{7}{2},\dfrac{7\sqrt{3}}{2}\right)$ .
