for the first one
Answer:
y is undefined
Step-by-step explanation:
if you have a vertical line, it will always be undefined
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: it would take her 5 weeks
You have to subtract 128 from 223 to find out how much money is left to earn. Which is 95. Then you must divide 95 divided by 19 because she get $19 each week and the answer is 5
