The area of an Equilateral triangle is given by the formula A= 3pi squared/4(s)Squared. Which formula represents the length of e

ad-work [718]

Answer:

The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is $\text{s}= \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}$ .

Step-by-step explanation:

We are given the area of an Equilateral triangle which is A = $\frac{\sqrt{3} }{4} \times \text{s}^{2}$ . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

So, the area of an equilateral triangle = $\frac{\sqrt{3} }{4} \times \text{s}^{2}$

where, s = side of an equilateral triangle

A = $\frac{\sqrt{3} }{4} \times \text{s}^{2}$

Cross multiplying the fractions we get;

$4 \times A = \sqrt{3} \times \text{s}^{2}$

$\sqrt{3} \times \text{s}^{2}= 4\text{A}$

Now. moving $\sqrt{3}$ to the right side of the equation;

$\text{s}^{2}= \frac{4 \text{A}}{\sqrt{3} }$

Taking square root both sides we get;

$\sqrt{\text{s}^{2}} = \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}$

$\text{s}= \sqrt{ \frac{4 \text{A}}{\sqrt{3} }}$

Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

Dilate the the triangle, scale factor = 3 (positive 3, ignore the

HACTEHA [7]

Answer:

The rule of dilation is $P'(x,y) = 3\cdot P(x,y)$ .

The vertices of the dilated triangle are $A'(x,y) = (-21, -18)$ , $B'(x,y) = (-15,-10)$ and $C'(x,y) = (-3,-15)$ , respectively.

Step-by-step explanation:

From Linear Algebra, we define the dilation by the following definition:

$P'(x,y) = O(x,y) + k\cdot[P(x,y)-O(x,y)]$ (1)

Where:

$O(x,y)$ - Center of dilation, dimensionless.

$k$ - Scale factor, dimensionless.

$P(x,y)$ - Original point, dimensionless.

$P'(x,y)$ - Dilated point, dimensionless.

If we know that $O(x,y) = (0,0)$ , $k = 3$ , $A(x,y) = (-7,-6)$ , $B(x,y) = (-5,-2)$ and $C(x,y) =(-1,-5)$ , then dilated points of triangle ABC are, respectively:
