R = 2 / (1 + sin <span>θ)
Using the following relations:
R = sqrt (x^2 + y^2)
sin </span>θ = y/R
<span>
R = 2 / (1 + y/R)
R</span>(1 + y/R<span>) = 2
</span><span>R + y = 2
R = 2 - y
sqrt(x^2 + y^2) = 2 - y
Squaring both sides:
x^2 + y^2 = (2 - y)^2
x^2 + y^2 = 4 - 4y + y^2
x^2 + 4y - 4

Answer:
Step-by-step explanation:
66.00 x 1.0825 = 71.445 rounded to $71.45
You take 8.25% and divide it by 100 which will give you 0.0825 by adding a 1 this will get you the sales tax and original amount.
Answer:
Step-by-step explanation:
-4 (-2x - 8) = -48
-4×(-2x)+4×8=-48
8x+32=-48
8x=-48-32
8x=-80
x=-10
The answer is -10
