Find all polar coordinates of point P where P = ordered pair 6 comma negative pi divided by 5.
Allushta [10]

Answer:

P(6,-π/6) = (6, -π/6 + 2nπ) and P(-6,-π/6) = (-6, -π/6 + (2n+1)π)

Step-by-step explanation:

We need to find all polar coordinates of

P = (6,\frac{-\pi }{6})

The polar coordinates of any point can be reresented by (r,Ф)

where

(r,Ф) = (r, Ф+2nπ) where n is any integer and r is positive

and

(r,Ф) = (-r, Ф+(2n+1)π) where n is any integer and r is negative.

So, in the question given, r = 6 and Ф = -π/6

So, Polar coordinates will be:

P(6,-π/6) = (6, -π/6 + 2nπ) where where n is any integer and r is positive

and

P(-6,-π/6) = (-6, -π/6 + (2n+1)π) where n is any integer and r is negative.

A bank advertises an interest rate of 4% per year, compounded monthly
Darina [25.2K]

Given :

Interest rate , r = 4 %.

To Find :

The APY .

Solution :

APY is given by :

APY=(1+\dfrac{r}{n})^n-1

Here , r is compound interest and n is number of time compounded .

So ,

APY=(1+\dfrac{r}{n})^n-1\\\\APY=(1+\dfrac{4}{12})^{12}-1\\\\APY=30.57\%

Therefore , APY is 30.57 % .

Hence , this is the required solution .
