The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
Easily we can use formula y=(x-h)^2 +k
as equation of a parabola if vertex was (h,k):
Y=(x-1)^2 + 3
and maybe node (2,6) is incorrect for this vertex of a parabola!!!
The second one should be the answer
Answer:
Federalists wanted a
centralized banking
system and Alexander
Hamilton, as Secretary of
the Treasury, proposed a
national bank in 1789.
• Antifederalists, like
Thomas Jefferson,
opposed this plan.
– They favored a
decentralized banking
system in which states
established and
regulated banks within
their borders.
