Find all of the polar coordinates of point P if P = (7,pi/3)
oee [108]

If P has Cartesian coordinates (7, pi/3), then its Polar coordinates are (square root of ((7)^2 + (pi/3)^2) , arcton (pi/21))

<u>Explanation</u>:

The given coordinates  ( 7 ,  π /3 )  look as if they are already in polar form (radius  =  7 , and angle  =  π/3).

but in case  ( 7 ,  π /3 )  really are Cartesian coordinates (i.e.  ( x , y ) = ( 7 ,  π/3 ) )

The radius is given by  √( x /2  +  y/ 2)  and  the angle by the  arctan  ( y ,x ).

9514 1404 393

Answer:

  285 centiliters

Step-by-step explanation:

Using the given conversion factor:

  1 quart = 0.95 L = 95 cL

  3 quarts = 3 × 95 cL = 285 cL

There are approximately 285 centiliters in 3 quarts.

__

Centi- is a prefix meaning 1/100th. So, 0.95 L (95 hundredths) is 95 cL.

S_A_V [24]

Answer:

25 extra litres

Ratio 2:3

2+3=5 so 35/5 =7

7x2 means she used 14 litres of fruit juice

7x3 means she used 21 litres of lemonade

if she has 10 litres of fruit juice left then she can use 10/2=5 5x3=15 15 litres of lemonade

10+15=25 so she can make 25 extra litres
