Polar coordinates : r= - 5, α= - 180⁰.
Rectangular coordinates :
x=r*cosα = (-5)*cos (-180⁰)=(-5)*(-1)=5
y=r*sinα = (-5)*sin(-180⁰)=(-5)*0=0
So, <span>(-5, -180°) (polar coordinates) is the same as (5,0) (rectangular coordinates).</span>
Answer:
C5
Step-by-step explanation: 10 x 2 = 20 so you add the 2 to the other one and get 4. Then half of 10 is 5 and half of 2 is 1, so add 1 to 4 and your answer is 5.
10x2= 20 +5= 25 Answer:5
A rational number is defined as a number that can be written
as a ratio of whole numbers. If it can't then it isn't.
Is 19:17 because u have to value the number of the first like this 78:807y :997
