Rewrite the rectangular equation x^2+y^2-8y=0 as a polar equation

mojhsa [17]

Answer:

We'll use the following identities:

r = √(x2 + y2), from which we also have r2 = x2 + y2

y = r*sinθ

First, let's re-write your equation:

r = 8*sin(θ). Multiply both sides by r:

r2 = 8r sin(θ)

Now, we'll use substitute using the identities:

x2 + y2 = 8y

Re-arrange and complete the square:

x2 + y2 - 8y = 0

x2 + (y-4)2 - 16 = 0

x2 + (y-4)2 = 16

This represents a circle with center (0,4), and radius 4.

James bought 12 cookies and ate 3 of them. He ate ____% of the cookies.

morpeh [17]

12 - 3 = 9
So there are 9/12 cookies left.
So then John ate 3/12 cookies.
3/12 = 1/4
Convert into a decimal. .
1/4 = 0.25
0.25 = 25%
So, James bought 12 cookies and ate 3 of them. He ate 25% of the cookies.

Randi has a party-sized sandwich that is 3/4 yard long. She will cut it into smaller sandwiches that are each 1/12 yard long. Wh

Elena L [17]

Answer:

The expression for number of sandwiches is $n=\frac{3}{4}\div\frac{1}{12}$

9 small sandwiches can be made.

Step-by-step explanation:

Given:

Length of party-sized sandwich (l) = 3/4 yard

Length of each small sandwich (s) = 1/12 yard

Now, let the total number of small sandwiches be 'n'.

Now, sum of all the lengths of small sandwiches will be equal to the length of the party-sized sandwiches.

Therefore, framing in equation form, we have:

Length of large sandwich = Length of small sandwich × Total number of small sandwiches.

$l=s\times n\\\\n=\dfrac{l}{s}$

Now, plug in the given values and solve for 'n'. This gives,

$n=\frac{3}{4}\div \frac{1}{12}\\\\n=\frac{3}{4}\times \frac{12}{1}\\\\n=\frac{36}{4}=9$

Therefore, 9 small sandwiches can be made.
