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).

)) What is the area of the shaded region?<br>

ahrayia [7]

The area of a triangle can be found by using the formula A = bh/2

To find the area of the shaded region (the green section), we can find the area of both triangles and subtract.

Large triangle:

A = 28*36/2

A = 1008/2

A = 504km²

Small triangle:

A = 15*19/2

A = 285/2

A = 142.5km²

Subtract both triangles:

504 - 142.5 = 361.5km²

Therefore, the area of the shaded region is <u>361.5</u>km²

Best of Luck!

Y = 7x + 4 where x is the number of weeks Anna saves and y is the total amount in her account<br>

AveGali [126]

Answer:

X= 4/7 or =0.57143

Step-by-step explanation:

1.1 Solve y-7x+4 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-7x+4 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is -4/1 so this line "cuts" the y axis at y=-4.00000

y-intercept = -4/1 = -4.00000

Calculate the X-Intercept :

When y = 0 the value of x is 4/7 Our line therefore "cuts" the x axis at x= 0.57143

x-intercept = 4/7 = 0.57143

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -4.000 and for x=2.000, the value of y is 10.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 10.000 - (-4.000) = 14.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 14.000/2.000 = 7.000

Geometric figure: Straight Line

Slope = 14.000/2.000 = 7.000

x-intercept = 4/7 = 0.57143

y-intercept = -4/1 = -4.00000
