Convert the Cartesian coordinates (2, -2) to polar coordinates. (2√2, 315°) (2√2, 330°) (2√2, 345°)
To convert from Cartesian Coordinates (x,y) to Polar Coordinates (r,θ):
r = √ ( x² + y² )
θ = arctan ( y / x )
r = √ [ 2² + (-2)² ] = √8 = 2√2
θ = arctan ( y / x ) = arctan (-2/2)
θ = arctan (-1) = n180º + 135º = nπ + 3π/4 => n=0, +-1, +-2, +-3...
So, a principal value of arctan(-1) in [0, π] is 3π/4 = 135º
There is another in [0, 2π] => 1π + 3π/4 = 7π/4 = 180º + 135º = 315º
Answer : (2√2, 315°)
Answer:
213 points
The y-intercept is how many points Jackson already scored, and the slope is how many points he is scoring every game.
Step-by-step explanation:
Jackson earns 28 points per game, so after 6 games, he earns 168 points (just multiply 6 by 28). He already scored 45 points, so if you add them together, he scored a total of 213 points.
The y-intercept is 45, what he already scored, and the slope is 28, how many points he scores per game.
Hope I helped!!!
