The length of a rectangle is three times the width. the area of the rectangle is 108sq in. what is the width of the rectangle?

Taya2010 [7]

Answer:

L = 3W

Area, A = L x W = 108 in2

Substitute L = 3W into the area equation, you get

A = 3W x W = 108

3W2 = 108

W2 = 108 / 3 = 36

W = √36 = 6 in

If 3 to the power y = x then y = ?

Oksanka [162]

Answer:

$y=\log_3(x)$

Step-by-step explanation:

$3^y=x$

$\ln(3^y)=\ln(x)$

$y\ln(3)=\ln(x)$

$y=\frac{\displaystyle\ln(x)}{\displaystyle\ln(3)}$

but if

$f(x)=\frac{\displaystyle\ln(x)}{\displaystyle\ln(3)}$

then since

$f(3)=\frac{\displaystyle\ln(3)}{\displaystyle\ln(3)}=1$

$f(x)=\log_3(x)$

so

$y=\log_3(x)$

or

$3^y=x$

$\log_3(3^y)=\log_3(x)$

$y\log_3(3)=\log_3(x)$

$\text{but }\,\log_3(3)=1, \text{so,}$

$y=\log_3(x)$
