ln(y+1)-lny=1+3lnx . Express y in terms of x, in a form not involving logarithms. (4 marks, Maths CIE A level)

Delicious77 [7]

$remember$
$ln(x)=log_e(x)$
$and$
$log_x(a)-log_x(b)= log_x( \frac{a}{b} )$
$and$
$log_a(b)=c$ means $a^c=b$
$and$
$blog(a)=log(a^b)$

$so$

$ln(y+1)-ln(y)=1+3ln(x)$
$ln( \frac{y+1}{y} )=1+ln(x^3)$

$minus$ $ln(x^3)$ $from$ $both$ $sides$

$ln( \frac{y+1}{y}-ln(x^3) )=1$
$ln( \frac{y+1}{yx^3})=1$
$log_e( \frac{y+1}{yx^3})=1$

$translate$

$e^1=\frac{y+1}{yx^3}$
$e=\frac{y+1}{yx^3}$

$times$ $both$ $sides$ $by$ $yx^3$

$eyx^3=y+1$

$minus$ $y$ $from$ $both$ $sides$

$eyx^3-y=1$
$y(ex^3-1)=1$

$divide$ $both$ $sides$ $by$ $(ex³-1)$

$y= \frac{1}{ex^3-1}$

12 square feet of paper at $1 per square feet

Shkiper50 [21]

Given data:
12 square feet of paper at 1 dollars per square feet
=> 12 square feet * 1 dollar = 12 dollars
4 feet of wood at 3 dollars per foot
=> 4 feet of wood * 3 dollars = 12 dollars
14 yards of string for 2 dollars per yard
=> 14 yards of string * 2 dollars = 28 dollars
Now let’s solve that total:
=> 12 dollars + 12 dollars + 28 dollars
=> 52 dollars.
Thus, Maria spent a total of 52 dollars in buying her need supplies.
