In Chemistry, the pH of a solution is defined by pH = -log10[H +), where H+ is the hydrogen ion concentration of the solution in moles per liter. At a river, the pH was measured as 2.36 x 10^-7 mol/L. A year later at the same river the pH was measured as 1.41 x 10^-8mol/L. How much did the pH
increased in one year?

Which of the following tables represents exponential functions?

Equation for the calculation double 2 and then add 5

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
