PLEASE HELP ME! Find the cube roots of 125(cos 288° + i sin 288°).
shutvik [7]
◆ COMPLEX NUMBERS ◆

125 ( cos 288 + i sin 288 )  can be written as -

125.e^i( 288) 
125.e^i( 288 +360 ) 
125.e^i( 288+ 720)

[ As , multiples of 360 can be added to an angle without changing any trigonometric functions or sign ]

To find the cube root , take the cube root of above 3 expressions ,

We get -
5 e^( i 96 ) 
5 e^( i 216 )  
5 e^( i 336 )

Now using Euler's formula , We rewrite above as -

5 ( cos 96 + i sin 96 ) 
5(c os 216 + i sin 216 ) 
5 ( cos 336 + i sin 336 ) Ans.

The distance from Gary's school to the corner market is 47 yards.The distance to the BART station is 12 times as far How far is
andre [41]

Answer:

The distance from Gary's school to  the BART station is 564 yards

Step-by-step explanation:

Let

x ----> the distance  from Gary's school to the corner market

y ----> the distance from Gary's school to  the BART station

we have

x=47\ yd

we know that

To find out the distance from Gary's school to  the BART station, multiply the distance from Gary's school to the corner market by 12

so

y=12x

substitute the value of x

y=12(47)=564\ yd

therefore

The distance from Gary's school to  the BART station is 564 yards
