We know that
<span>The nine radii of a regular Nonagon divides into 9 congruent isosceles triangles
</span>therefore
[the area of <span>a regular nonagon]=9*[area of isosceles triangle]
</span>[area of isosceles triangle]=b*h/2------> 15*20.6/2----> 154.5 cm²
so
[the area of a regular nonagon]=9*[154.5]------> 1390.5 cm²
the answer is
1390.5 cm²
Answer:
$546,875
Step-by-step explanation:
if the trailer brand new costs $625,000 and decreases by 12.5% you want to find 10% which is $62,500. then you want to find 5% which would be $31,250. but you want 2.5% so you need to divide $31,250 by 2 which is $15,625. add $62,500 and $15,625 together which is $78,125. then do $625,000-$78,625 which gets you $546,875.
The equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.
<h3>What is the equation of line?</h3>
The equation of the line is the way of representation of a line in the equation form.
The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
The formula to find equation of line is,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
Here, x and y are the coordinate and subscript (1,2) used for the first and second point.
The points from which the line passes through are (2,5) and (-2,-3). Put the values,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
(y-(-2))={(-3-5)/(-2-2)}(x-2)
y+2={-8/-4}(x-2)
y+2=2(x-2)
y+2=2x-4
y=2x-4-2
y=2x-6
Thus, the equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.

Answer:
The numerical length of RS is 10 units
Step-by-step explanation:
* <em>Lets explain How to solve the problem</em>
- Point R is on line segment QS
- The length of QS is (5x - 2)
- The length of QR is (3x - 6)
- The length of RS is (4x - 2)
- <em>The length of QS is the sum of the lengths of QR and RS</em>
∵ QS = QR + RS
∴ (5x - 2) = (3x - 6) + (4x - 2)
- Simplify the right hand side by adding like terms
∴ 5x - 2 = (3x + 4x) + (-6 + -2)
∴ 5x - 2 = 7x + -8 ⇒ (+)(-) = (-)
∴ 5x - 2 = 7x - 8
- Add 8 for both sides
∴ 5x + 6 = 7x
- Subtract 5x from both sides
∴ 6 = 2x
- Divide both sides by 2
∴ x = 3
- <em>To find the length of RS substitute the value of x in its expression</em>
∵ RS = 4x - 2
∵ x = 3
∴ RS = 4(3) - 2 = 12 - 2 = 10
∴ The numerical length of RS is 10 units
