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
).

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.
Answer:
26π
Step-by-step explanation:
The equation for circumference is
c = 2πr
using r = 13
c = 2π(13)
Rearrange
c = 2(13)π
Simplify
c = 26π
Answer:
25 extra litres
Step-by-step explanation:
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
