Write down a parametric form of the circle centered at (????1; 2) with radius 3. indicate the parameter interval that you used.

1 answer:

7 0

Parametric form of a circle is x = h + r cos t, y = k + r sin t where (h , k) is coordinates of the center of the circle. r is the radius

so for this circle the equations are
x = 1 + 3 cos t and y = 2 + sin t

xxTIMURxx [149]

Answer:

x = first piece

14 - x = second piece

Step-by-step explanation:

Since we know that the board is 14 feet then to find the size of the second piece, we just take the full length of the board and then subtract it to the first piece's length.

Answer:

the download cost for a song is $1 and $11 for a movie

Step-by-step explanation:

According to the questions, the following equations are as follows:

Let us assume the song be x

And, the movies be y

So,

20x + 13y = $163.........(i)

13x + 13y = $156........(ii)

Now solve substract second equation from the first equation

7x = $7

x = $1

And the y value is

20 + 13y = $163

13y = $163 - $20

13y = $143

y = $11

Hence, the download cost for a song is $1 and $11 for a movie

Please answers all these questions for me need help too pass plz help☺

Please take 1 minute, and really read the example solution
under problem #12. All of the other eight problems on the
sheet are solved in exactly the same way:

Multiply each side of the equation by the denominator of
the fraction ... the number under the variable (the letter).

This easy step will get you the answer to each of the
eight problems.

I can't help noticing that the title of the sheet is 'extra PRACTICE' .
If someone handed you the answers, then you would not get the
practice. That would be just like stealing from you, and would be
just plain mean.
