Answer:
(5*sqrt(2), 5pi/4)
Step-by-step explanation:
In Polar coordinates, tan(theta)=y/x and r=sqrt(x^2+y^2)
tan(theta)=-5/5=-1. Theta=5pi/4
r=sqrt(5^2+5^2)=5*sqrt(2)
Hence the Polar coordinate is (5*sqrt(2), 5pi/4)
Answer:
Step-by-step explanation:
add all of them and then see if they right
Do distance divided by time to get the speed.
200 / 2.5 = 80.
The speed is 80 miles per hour(mph).
Hope this helps :)
