Answer:
16
Step-by-step explanation:
64=1,2,4,8,<u>16</u>,32,64
48=1,2,3,4,6,8,12,<u>16</u>,24,48
B, n to the 3rd power + 4n to the 2nd power +8n -16
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
