A group of scientists studied the effect of a chemical on various strains of bacteria. Strain A started with 12000 cells and decreased at a constant rate of
4000 cells per hour after the chemical was applied. Strain B started with 6000 cells
and decreased at a constant rate of 3000 cells per hour after the chemical was
applied. When will the strains have the same number of​ cells? Explain.

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle
