How can you use functions and graphs to represent periodic data?

1 answer:

6 0

<span>Graphs can be used to represent periodic data because you can show rise and fall of something and express situations that may be tough to show in writing.</span><span>

In the case that the periodic data is on the range of the function (the y axis)

You can use functions to represent periodic data:

example y=sin(x)</span>

Please help me thank you

Reptile [31]

Answer:

$y \geqslant \frac{1}{4} x - 1$

$4 \times y \geqslant \frac{1}{4} \times 4x - 4 \times 1$

$4y \geqslant x - 4$

$4y + x \geqslant - 4$

$5yx \geqslant - 4$

$yx \geqslant - 4 - 5$

$yx \geqslant - 9$

you're welcome I think I don't really know whether I'm finding x or y or yx

Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3). Determine the point of intersection of the medians, and state the coordin

emmainna [20.7K]

Answer:

(-5, 3)

Step-by-step explanation:

Let O(x, y) be the centroid of the triangle.

The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.

The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.

For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:

$x=\frac{3 + (-7)+(-11)}{3}=-5\\\\y=\frac{-3 + 9 + 3}{3} =3$

The centroid is at (-5, 3)
