Question 6 (Essay Worth 2 points)<br> Find all polar coordinates of point P = (2, 14°).

andrey2020 [161]

Answer:

(2,14°+360n) and (-2,14°+(2n+1)180°)

Step-by-step explanation:

You start out with (2, 14°)

The polar coordinate can be written as (r, 0) = (r, 0+2nπ) or

(r,0)=(-r,0+2(n=1)π), where n is any integer.

The polar coordinates point : p=(r,0) = (2,14°)

For the positive value of r, the polar coordinate can be written as

p=(2,14°) = (2,14°+360n°), where n is any integer.

For the negative value of r , the polar coordinate can be written as

p=(2,14°) = (-2,14°+(2n+1)180°), where n is any integer.

All the polar coordinates of point P are(2,14°+360n) and (-2,14°+(2n+1)180°).

Which expression is equal to 54⋅58 ? <br> 512 54 52 5−4

nignag [31]

Not sure if it's one of the answer you listed.
The • means multiplication, so it would be
54 times 58, which equals 3,132.

(6+√-64)(3-√-16) Multiply. This is urgent, please explain this to me!

romanna [79]

Answer:

Step-by-step explanation:

$\sqrt{-64}$ and $\sqrt{-16}$ can be expressed in complex form, with $\sqrt{-1}$ = i

$\sqrt{-64}$ = $\sqrt{64(-1)}$ = $\sqrt{64}$ × $\sqrt{-1}$ = 8i

$\sqrt{-16}$ = $\sqrt{16(-1)}$ = $\sqrt{16}$ × $\sqrt{-1}$ = 4i

the factors can then be expressed as

(6 + 8i)(3 - 4i) ← expand using FOIL

= 18 - 24i + 24i - 32i² [ i² = ( $\sqrt{-1}$ )² = - 1 ]

= 18 - 24i + 24i + 32 ← collect like terms

= 18 + 32 + 0

= 50
