Answer:

Part 1) $x=-0.07$

Part 2) $y=2.48$

Step-by-step explanation:

Part 1) we have

$15^{-9x} =6$

Solve for x

Apply log both sides

$log(15^{-9x})=log(6)$

$-x*(9log(15))=log(6)$

$x=-log(6)/(9log(15))$

$x=-0.07$

Part 2) we have

$e^{y}=12$

Apply ln both sides

$ln(e^{y})=ln(12)$

$y*ln(e)=ln(12)$

Remember that

$ln(e)=1$

$y=ln(12)$

$y=2.48$

Find the approximate side length of a square game board with an area of 171 in?

Makovka662 [10]

<em>Greetings from Brasil...</em>

According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²

The area of a square is given by the expression:

A = S²

<em>where S is the side of the square - just what we want to know</em>

So:

A = S²

171 = S²

√171 = S
