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

<h3>S ≈ 13.08in</h3>

Answer:

The value of f(x) when x=-1 is 0.5

Therefore $f(-1)=0.5$

Step-by-step explanation:

Given that y=f(x)= $2^x$

to find the f(x) when x=-1 :

That is to find f(-1)

Put x=-1 in the given function f(x)= $2^x$

$f(-1)=2^{-1}$

$=\frac{1}{2}$

$=0.5$

Therefore $f(-1)=0.5$

The value of f(x) when x=-1 is 0.5
