Answer:

2.5 or $\frac{5}{2}$

Step-by-step explanation:

5 x $\frac{1}{2}$ = 2.5

This is because half ( $\frac{1}{2}$ ) of 5 is 2.5

2.5 as a fraction is $\frac{5}{2}$ .

Hope this helps!

The rectangle has an area of x to the second power plus 13x + 36 sq.Meters and a length of x + 9 meters. What expression represe

elena-s [515]

Answer: the expression for the width is x + 4

Step-by-step explanation:

The area of the rectangle is expressed as

Area = x² + 13x + 36 square meters.

The length is expressed as

L = x + 9 meters

To determine the expression for the width of the rectangle, we would factorize the expression for the area. Hence

x² + 13x + 36 = 0

We would find two numbers such that their sum or difference is 13x and their product is 36x². The two numbers are 9x and 4x. Therefore,

x² + 9x + 4x + 36 = 0

x(x + 9) + 4(x + 9) = 0

(x + 4)(x + 9)

Therefore, the expression that represents the width of the rectangle is x + 4

Is domain of f(x,y) = 1 + (4 -y^2)^1/2 open, closed or neither<br><br> is it bounded or unbounded?

omeli [17]

Answer:

Closed and Bounded.

Step-by-step explanation:

Hi there!

1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:

$f(x,y) = 1 + (4 -y^2)^{\frac{1}{2}} \:id\:est\:f(x,y)=1+\sqrt{(4 -y^2)}$

Since every quadratic root are defined for values $\geq$ 0 then, this help us to understand that we need calculate what interval this Domain is:

$4-y^{2} \geq 0\\4-y^{2}-4\geq -4\\-y^{2}\geq-4 \\y^{2}\leq4\\-2\leq y\leq 2$

$D=[-2,2]$

2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.

Bounded functions have all of their points contained by some circle origin centered. Check it out below.
