First I made equations for the perimeter (p) in terms of the width (w) and same for the length (l).

Then, since all the sides added together equaled the perimeter, I made the perimeter equation equal to all the sides added together, all in terms of width (no other variables than w).

Solving that algebraically, you can find w. And then plug that back into the equation for length to find length.

w=8, l=11

Answer

x=2 and y=2√2

Step-by-step explanation:

$\sin( \alpha ) = \frac{2 \sqrt{2} }{x } \\ x = \frac{2 \sqrt{2} }{ \sin(45) } \\ x = 4 \\ {x}^{2} = {y}^{2} + 2 \sqrt{2} \\ {4}^{2} = {y}^{2} + (2 \sqrt{2 \: )}^{2} \\ 16 = {y}^{2} + 8 \\ 16 - 8 = {y}^{2} \\ y = \sqrt{8} \\ y = 2 \sqrt{2}$

What is the lowest value of the range of the function shown on the graph?

insens350 [35]

The complete question in the attached figure

we know that
the range is the y-value of the function
so
the lowest y-value on this graph is y = -2.

the answer is
y=-2
