Answer:

The radius of the given circle ( r ) = 2√2

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the center of the circle C = ( -2,1)

Given a point on the circle P = (0,3)

The distance between the center and point is called the radius of  the circle

CP = radius of the circle

<u><em>Step(ii):-</em></u>

CP = \sqrt{x_{2} - x_{1})^{2} +(y_{2} -y_{1} )^{2}  }

CP = \sqrt{(0 - (-2))^{2} +(3-1)^{2}  } \\CP = \sqrt{4+4}

CP = √8 = \sqrt{4 X 2} = 2\sqrt{2}

<u><em>Final answer:-</em></u>

The radius of the given circle ( r ) = 2√2

A textbook store sold a combined total of 477 sociology and math textbooks in a week. The number of sociology textbois sold was
denpristay [2]

Answer:

The correct answer is 218 math textbooks and 259 sociology textbooks.

Step-by-step explanation:

To solve this problem, we can make a system of equations. Let the number of sociology textbooks sold be represented by the variable "s" and the number of math textbooks sold be represented by the variable "m". Using these variables, we can make two equations:

s + m = 477

m + 41 = s

There are many ways to solve this system of equations. One approach we can take is substituting the value for s given by the second equation into the first equation. This is modeled below.

s + m = 477

(m + 41) + m = 477

Combining like terms on the left side of the equation yields:

2m + 41 = 477

Subtracting 41 from both sides of the equation gives us:

2m = 436

Finally, dividing both sides of the equation by 2 gives us:

m = 218

To solve for the number of sociology textbooks, we can substitute into either of our original equations.

m + 41 = s

(218) + 41 = s

s = 259

Therefore, your answer is m = 218 and s = 259, or 218 math textbooks and 259 sociology textbooks were sold.

Hope this helps!
