Suppose you invest $50 a month in an annuity that earns 4.8% apr compounded monthly. how much money will you have in this account after 10 years?

$6,288

Step-by-step explanation:

$50x12 = $600

4.8x600 = 2280

2280/100 = $28.80  

600+28.80 = 628.80

628.80x10 (10 years) = $6,288

You're gonna get a $288 profit in the course of 10 years.

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
