Answer:

Graph of Option D represents $y=\sqrt{x}$

Step-by-step explanation:

we are given our function as

$y=\sqrt{x}$

squaring on both sides we get

$y^2=x$

It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .

However our original function is $y=\sqrt{x}$

Domain of $y=\sqrt{x}$ is all positive values of x

And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y

Hence we erase the graph of $y^2=x$ below x axis to obtain the graph of

$y=\sqrt{x}$

Steven has a rectangular rug with a perimeter of 16 feet. The width of the rug is 5 feet. What is the length of the rug?

boyakko [2]

$\boxed{\boxed{\text{Perimeter = 2(Length + Width)}}}$

Given that the perimeter is 16ft and width is 5 ft,
$16 = 2( Length + 5)$

Distribute 2:
$16 = 2Length + 10$

Take away 10 from both sides:
$2Length = 16 - 10$

Evaluate the right hand side:
$2Length = 6$

Divide by 2 on both sides:
$Length = 3$

$\boxed{\boxed{\text{Answer: Length = 3 ft}}}$
