A regular pentagon is inscribed in ur let of radius 8cm. find the length of one side of the polygon

Sergio039 [100]

9514 1404 393

Answer:

9.404 cm

Step-by-step explanation:

A regular polygon with n sides inscribed in a circle of radius r will have a side length given by ...

s = 2r·sin(180°/n)

For r = 8 and n = 5, this gives a side length of ...

s = 2·8·sin(180°/5) = 16·sin(36°) ≈ 9.404 . . . cm

What type of conic is given by the equation 4x^2+9y^2=36

zvonat [6]

Answer:

This is equation of ellipse

Step-by-step explanation:

we are given

$4x^2+9y^2=36$

We can see that right side is 36

so, we can make right side as 1 by dividing both sides by 36

$\frac{4x^2+9y^2}{36} =\frac{36}{36}$

$\frac{4x^2+9y^2}{36} =1$

$\frac{4x^2}{36}+\frac{9y^2}{36} =1$

we can simplify it

$\frac{x^2}{9}+\frac{y^2}{4} =1$

we can rewrite it as

$\frac{x^2}{3^2}+\frac{y^2}{2^2} =1$

now, we can compare it with standard equation of ellipse

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2} =1$

we can see that both equations are similar

so, this is equation of ellipse

A garment dealer buys for Rs.10,000 and spend Rs.800 on freight. He seeks the entire stock for Rs.12,960. Find his loss/profit p

jeyben [28]

Answer:

Profit percentage $=20\%$ .

Step-by-step explanation:

Given: A garment dealer buys goods for $\text{Rs.}\:10,000$ and spend $\text{Rs.}\:800$ on freight. He seeks the entire stock for $\text{Rs.}\:12,960$ .

To find: His loss/profit percentage.

Solution:

We have,

Cost price of goods $=\text{Rs.}\:10,000$

Spent on freight $=\text{Rs.}\:800$

So, total cost of goods $=\text{Rs.}\:10000+\text{Rs.}\:800=\text{Rs.}\:10,800$

Selling price of entire stock $=\text{Rs.}\: 12,960.$

Now, Profit $=\text{Selling price}-\text{Cost price}$

So, Profit $=\text{Rs.}\:12, 960-\text{Rs.}\:10,800=\text{Rs.}\:2160$

Now,

$\text{Profit\:\%}= \frac{\text{Profit}}{\text{Cost price}} \times 100\%$

$\implies\text{Profit\:\%}= \frac{2160}{\text{10,800}} \times 100\%$

$\implies\text{Profit\:\%}= \frac{2160}{108}\%$

$\implies\text{Profit\:\%}= 20\%$

Hence, profit percentage $=20\%$ .
