Using only the numbers 1 through 14. add the numbers to get 28 (using 4 numbers), 14 (using 3 numbers), 30 (using 4 numbers), and 33 (using 3 numbers)

The equation given is: r = log(a/t) + dwe are also given that: time (t) = 4 secondsweakening of earthquake due to distance from epicenter (d) = 2substitute in the equation, we will get: r = log(a/4) + 2graphing the above equation, we would get the graph shown in the attached image.note: i used "x" instead of "a" in writing the equation.hope this : )
