Find the center and radius of the circle x^2+y^2-10x-12y+45=0.

BARSIC [14]

Answer:

The center is (5, -6) with a radius of r

Step-by-step explanation:

First put the equation in Standard Form for a circle:

(x + a)² + (y + b)² = r²

Now, Group the term

x² + y² - 10x - 12y + 45 = 0

x² - 10x + y² - 12y = - 45

Then, The x and y terms must be perfect squares

x² - 10x + 25 + y² - 12y + 36 = - 45 + 25 + 36

add constant both sides we get,

x² - 10x + 25 + y² - 12y + 36 = 16

Now, Simplify

(x - 5)² + (y + 6)² = 16

√(x - 5)² + (y + 6)² = √16

x - 5 + y + 6 = 4

Here, (a,b) = (5, -6) and r² = 16, with r = 4

Thus, The center is (5, -6) with a radius of r

Brandy set her watch 4 seconds behind and it falls behind another 1 second every day. How many days had it been since brandy las

kari74 [83]

Answer:

18 days

Step-by-step explanation:

Let x represent number of days.

We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall $1x$ seconds behind in x days.

We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total $x+4$ seconds in x days.

Since Brady's watch is 22 seconds behind, so we will equate $x+4$ by 22 to solve for x as:

$x+4=22$

$x+4-4=22-4$

$x=18$

Therefore, Brandy set her watch 18 days ago.
