A circle has diameter endpoints of A(5, 10) and B(-3,4). What are the coordinates of the center of the circle?
0 (4, -2)
o(-11, -2)
O (13, 16)
o (1,7)

(1,7)

Step-by-step explanation:

Hi there!

The center of the circle is located in the middle two diameter endpoints. To find the coordinates of the center of the circle, calculate the midpoint of the two endpoints A and B.

Midpoint: where the two given points are and

Plug in the given points A(5, 10) and B(-3,4):

Therefore, the center of the circle have coordinates of (1,7).

I hope this helps!

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
