The given rational functions is graphed in the figure is Option B. f(x) = 1/ ( x-2) (x + 5) is correct.

<h3>What is a function?</h3>

The function is a type of relation, or rule, that maps one input to specific single output.

Here, a graph is given.

We need to find which of the given rational functions is graphed in the figure.

On x-axis, 1 unit = 2 units

Clearly, we can see the graph is not defined at point x = 2 and at x = -5.

Corresponding to x = 2, factor is (x - 2) .

Corresponding to x = -5, factor is (x + 5) .

So, this graph is of the rational fraction

Hence, Option B. f(x) = 1/ ( x-2) (x + 5) is correct.

The equation x²– 8x – 5 = 0 can be transformed into the equation (x - p)² = q, where p and q are real numbers. What are the valu

Juliette [100K]

The form (x - p)^2 = q is the form that completing the square will leave us with.

---Add 5 to both sides

x^2 - 8x = 5

---Divide the b term by 2, and square it. Then, add that number to both sides.

-8/2 = -4

(-4)^2 = 16

x^2 - 8x + 16 = 5 + 16

x^2 - 8x + 16 = 21

---Factor!

(x - 4)^2 = 21

p = 4

q = 21

Hope this helps!! :)

What is the equation of the yellow line

katovenus [111]

Answer:

y = - $\frac{5}{3}$ x -2

Step-by-step explanation:

The line is going down to the right so it has the negative slope, with a y- intercept of (0, -2) and a slope of m = rise/run = -5/3

Plz do this question if you did I will very appreciated you. plz.

The area formula of a circle is $r^{2}$ × π.

With that being said, we can solve both problems!

Starting with part A:

-The radius we know is 21cm. From there, we can substitute in our formula with the new value.

$21^{2}$ x π

From there, we can square our radius:

(21 x 21) x π

(441) x π

And finally, we can multiply by pi to get our answer.

(441) x π

1385.44236023

Which rounded to the nearest tenth is 1385.4. Therefore, the area of the porthole is 1385.4 centimetres.

The second part can be followed with the same process, hopefully you understand the concept enough to where you're comfortable solving problems like this on your own. Feel free to reach out if you have any further trouble!

<em>Hope this helped! :)</em>

Every _____ tessellates.

Ludmilka [50]

<span>Every hexagons tessellates. Hexagons always tessellates when perfectly combined and aligned especially when the x sides and the y sides are parallel to each other. An example of tessellating hexagons is bee hive. Bee hives have perfect tessellating hexagons.</span>
