Answer:

Step-by-step explanation:

The equation of a proportional relationship is

y = kx ← k is the constant of proportionality

Divide both sides by x

$\frac{y}{x}$ = k

To find k use any ordered pair from the table

Using (2, $\frac{5}{2}$ ) , then

k = $\frac{2}{\frac{5}{2} }$ = 2 × $\frac{2}{5}$ = $\frac{4}{5}$

The Pyraminx is a Rubik's cube-type toy in the shape of a tetrahedron. The Pyraminx shown below has edges 15\,\text{cm}15cm long

____ [38]

Answer:

8.727

Step-by-step explanation:

Since the below edge, d = 15 cm, and the height, h = 12.2 cm, we will use the Pythagorean theorem to find the distance r.

$d^2=r^2+h^2$

$(15)^2 = r^2+(12.2)^2$

$r^2 = (15)^2-(12.2)^2=225-148.84=76.16$

$r=\sqrt{76.16}=8.727$

Help on the second graph?

patriot [66]

Answer:

The 2nd Graph is a function.

Step-by-step explanation:

You can tell it's a function because if you flatten the individual line segments along the x-axes, they all connect to form one long line.

HOWEVER, if some of the dots at the end of each line segment were empty circles instead, then it would not be considered a function. You can think of these as holes, not allowing the line to connect in those or that area.

Did that help? ;-;
