ANSWER:
r = 
Explaination:
Convert the given curve into the the polar form.
x = rcosθ
y = rsinθ
in f(x,y) = (x²-y²) - √(x²+y²) = 0
put the values of x & y in given curve equation.
We get at,
g(r,θ) = (r²cos²θ - r²sin²θ) - √(r²cos²θ + r²sin²θ) = 0
g(r,θ) = r²(cos²θ - sin²θ) - √r² = 0
We know that,
cos²θ - sin²θ = cos2θ
g(r,θ) = r²(cos2θ) - r = 0
Solve for r
Finally we get:
r = 
Answer:
x = -5/2
Step-by-step explanation:
Step-by-step explanation:
first bro + 2nd bro + 3rd bro
x + (x+2) + (x+4) = 93
x = 87/3
x= 29
Answer:
Each child will receive 0.125 (or 12.5%) of the estate.
Step-by-step explanation:
If the surviving spouse gets one half of the estate, the other half have to be divided among the four surviving children.
So its 0,5 divided among the 4 surviving children. That is 0.125 or 12.5% of the estate.
Each child will receive 0.125 of the estate.
