Find all polar coordinates of point p where p = ordered pair 5 comma pi divided by 3.
Aleonysh [2.5K]

Find all polar coordinates of point p where p = ordered pair 5 comma pi divided by 3.

The polar coordinate of any point can be written as:

<span>(r, θ) = (r, θ + 2nπ)                                           --> when positive</span>

<span> (r, θ) = [ - r, θ + (2n + 1)π ]                           --> when negative</span>

<span> where n is any integer.</span>

The polar coordinates of this given point P is: P = (r, θ) = (5, π/3).

When the value of r is positive, the polar coordinate is written as P= (5, π/3) = (5, π/3 + 2nπ)

where n is any integer.

When the value of r is negative, the polar coordinate is written as P = (5, π/3) = [ - 5, π/3 + (2n + 1)π] where n is any integer.

 

Therefore all polar coordinates of point P are (5, π/3 + 2nπ) and [ - 5, π/3 + (2n + 1)π ].

(−7c+8d)0.6 distributive property
Ksivusya [100]

We are given

(-7c+8d)0.6

we can use distribute property

Distributive property:

(A+B)C=A*C+B*C

so, we can write it as

(-7c+8d)0.6=-7c*0.6+8d*0.6

(-7c+8d)0.6=-7*0.6c+8*0.6d

now, we can multiply terms

and we get

(-7c+8d)0.6=-4.2c+4.8d..............Answer
