In 2007, the fdic’s insurance limit was $100,000 per person per bank. approximately 62% of gil’s deposits were insured by the fdic. which of the following was a possible setup for gil’s deposits?

a.
a $13,000 money market account at bank t; a $31,000 cd, $44,000 savings account, and $16,000 checking account at bank u; a $70,000 cd and $28,000 money market account at bank v
b.
a $54,000 checking account and $84,000 savings account at bank t; a $28,000 money market account, $27,000 savings account, and $20,000 cd at bank u; a $130,000 cd at bank v
c.
a $60,000 money market account and $70,000 savings account at bank t; a $40,000 checking account and $92,000 savings account at bank u; a $45,000 cd and $75,000 checking acount at bank v
d.
a $108,000 savings account and $46,000 cd at bank t; a $36,000 money market account and $38,000 cd at bank u; a $63,000 checking account, $80,000 savings account, and $70,000 money market account at bank v

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

can you make your screen more see able?

then i might be able to .
