The water level in a full water tank changes by the same amount each day when the tank gets a leak. the total change in the water level is -128 gallons after 16 days. what was the daily change in the amount of water in the water tank

it lost 128 gallons in 16 days so divide 128 by 16 to find the daily lost

128/16 = 8 gallons a day were lost

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
