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:
2/5 of a mile
Step-by-step explanation:
The easiest approach is to realise that one hour is 3 times longer than
20 minutes. The longer the time, the more they will pave.
2/5 of a mile, in 20 minutes, how much in 60 minutes?(#)
They will pave 3 times more.
2/15 x 3/1 = 6/15 of a mile
6/15 = 2/5 of a mile
Answer:
if u divide it then slop it u will get your answer
The answer to your question is Y
Answer:
x = 60°
Step-by-step explanation:
Special Angles :
sin = opposite divided by hypotenuse
opposite of angle 60° is square root of three
hypotenuse is two
