Answer: 32w
Step-by-step explanation:
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:
40 square feet
Step-by-step explanation:
A calculator fitting the data with an exponential model shows the annual multiplier is approximately 1.0367.
The effective annual interest rate is 3.67%.
-9n plus 9n is zero 3-8 is -5
