Y is directly related to x and y is 81 when x is 27 the constant of.variation is

suter [353]

Answer:

The constant of variation is 3

Step-by-step explanation:

Given.

$y=81$

$x=27$

And y is directly related to x

$y$ ∝ $x$

Here k is constant of variation

$y=kx$

$k=\frac{y}{x}$ --------------(1)

Put the $y$ and $x$ value in equation 1.

$k=\frac{81}{27}$

$k=3$

So, the constant of variation is 3.

Here is the question !

Delvig [45]

Answer:

Step-by-step explanation:

Co-ordinates of F, G and H are:

F (-4, 5)

G (1, 10)

H (-9, 10)

You can find the lengths of sides by using the distance formula:

length(FG) = $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}$ = $\sqrt{(1-(-4))^{2} + (10-5)^{2}} = 5\sqrt{2}$ units

Similarly,

length(GH) = 10 units

length(HF) = $5\sqrt{2}$ units

Hence, perimeter will be:

P = length(FG) + length(GH) + length(HF) = $10(\sqrt{2} + 1)$ units
