Help please! I already tried doing this but I didn't get the answer right, and I don't know where I went wrong
Sladkaya [172]

I think factorizing everything you can first will make the simplification ... well, simpler.

\dfrac{x^2 - 3x}{x^2 + 13x + 36} \div \dfrac{x^2+7x}{x^2+16x+63} = \dfrac{x(x-3)}{(x+4)(x+9)} \div \dfrac{x(x+7)}{(x+7)(x+9)}

The factors of x+7 in the second rational expression cancel:

\dfrac{x^2 - 3x}{x^2 + 13x + 36} \div \dfrac{x^2+7x}{x^2+16x+63} = \dfrac{x(x-3)}{(x+4)(x+9)} \div \dfrac{x}{x+9}

Now, use the property

\dfrac ab \div \dfrac cd = \dfrac ab \times \dfrac dc

(this is the property of multiplication having to do with multiplicative inverse, or "inverting the divisor" as the question calls it) to write

\dfrac{x^2 - 3x}{x^2 + 13x + 36} \div \dfrac{x^2+7x}{x^2+16x+63} = \dfrac{x(x-3)}{(x+4)(x+9)} \times \dfrac{x+9}x

and we see some more cancellation, namely of the factors of x and x+9.

\dfrac{x^2 - 3x}{x^2 + 13x + 36} \div \dfrac{x^2+7x}{x^2+16x+63} = \boxed{\dfrac{x-3}{x+4}}

How long will it take your money to double if you put $500 into an account compounded quarterly at 2.9%?
vitfil [10]
<h3>Answer: About 24 years</h3>

=======================================================

Work Shown:

A = P*(1+r/n)^(n*t)

1000 = 500*(1+0.029/4)^(4*t)

1000 = 500*(1.00725)^(4*t)

1000/500 = (1.00725)^(4*t)

2 = (1.00725)^(4*t)

log(2) = log( 1.00725^(4*t) )

log(2) = 4*t*log( 1.00725 )

4*t*log( 1.00725 ) = log(2)

t = log(2)/( 4*log( 1.00725 ) )

t = 23.9881659971072 The value is approximate

t = 24 when rounding to the nearest full year

It takes approximately 24 years to double your money.
