Polar form: (r,θ)
Using these formulas:
x²+y²=r²
tan(θ)=y/x
We have the point (1,1) in cartesian coordinates. We need to find r and θ to get it in polar form.
r²=1²+1²
r²=2
r=±√2
tan(θ)=1/1
tan(θ)=1
θ=π/4 radians or 45 degrees
Polar coordinates: (√2,π/4)
Those answer choices look strange. Are you sure these are the right answer choices?
Answer:
4/5 - 3/10 is 0.5.
Step-by-step explanation:
You want to divide top and bottom (Whatever you do to one side do to the other) So start off dividing 5 by 10 which wil give you 0.5, next you want to divide 4 by 3 which gives a repeating decimal so youll use the whole decimal (0.5) as an answer
Answer:
I think 720 would be the right answer!!
Answer:
Step-by-step explanation:
Let l be the length and w be the width of the rectangle
Given:
The length of the rectangle is 4 meters more than the width.
The length of the rectangle is
The perimeter of the rectangle should be less than 100 meters.
The perimeter of the rectangle is 
and it is less than 100 m.
So, the equation is.
Put length of the rectangle in above equation.
Therefore, the inequality expresses all of the possible widths is
