37.025 = thirty-seven and twenty-five thousandths
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: 25%
Step-by-step explanation:
From the question, we are informed that Allison earned $200 the first month she worked and $250 the second month she worked.
The percentage increase in her salary will be calculated as:
= Salary Increase / Old salary × 100
= (250 - 200) / 200 × 100
= 50/200 × 100
= 1/4 × 100
= 25%
The percentage increase is 25%
