The area of a square garden is 128m sqared.how long is the diagonal
weqwewe [10]

The area of a square is  (side)².
If the area is  128m², then the side is  (√128) meters. (That's 8√2.)

The diagonal is the hypotenuse of the right triangle you get
if you slice the square in half along the diagonal.  Its length is
given in the words of Old Pythagoras:

               c² = a² + b²

'a' and 'b' are sides of the square, so

             c² = (√128)² + (√128)²

                 =    2 (√128)²

              c  =  √ (2 x 128)  =  √256  =  16 meters .

The function y = 60x 1+0.625x models the moose population in a small New Hampshire forest over a period of time. What is a reaso
Nitella [24]
I think that the correct function in your question should be y = 60x⁻¹ + 0.625x.

With that said, the answer is A. <span>0 < x < ∞
By the process of trial and error of the choices, we can see that this choice satisfies the equation. Take note that y models moose population, so y should always be positive. </span>
