- If you travel 100 miles in two hours, then your average speed for the trip is Average speed=_________=________arrow_forwardThe volume of a gas in a container varies inversely as the pressure on the gas. If a container of argon has a volume of 336 cubic inches under a pressure of 2,500 psi, what will be its volume if the pressure is decreased to 2,000 psi?arrow_forwardThe area of a circle varies directly as the square of the radius. A circular pizza with a radius of 6 inches has an area of 113.04 square Inches. a. Write the equation that relates the area to the radius. b. What is the area of a pizza with a radius of 9 Inches?arrow_forward

Show that 95% of the radioactive nuclei originally present in a sample will disintegrate within three mean lifetimes, i.e., by time t=. Thus, the mean life of a k nucleus gives a quick way to estimate how long the radioactivity of a sample will last. ..... - kt If 95% of a sample has decayed, there is 5% remaining. How can you use the radioactivity equation y(t) = yo e to find when 5% of the sample is remaining? A. Set y(t) equal to 0.05 and solve for t. B. Evaluate y(0.05). C. Set y(t) equal to 0.05y, and solve for t. D. Evaluate y(5). Perform the operation determined in the previous step. Yo e - kt 0.05yo - kt e = 0.05 Divide both sides by yo: = In 0.05 Take the natural logarithm of each side. In 0.05 t = Solve for t. Approximate In 0.05. In 0.05 x (Round to three decimal places as needed.) Since this value is approximately equal to then 95% of a sample will…arrow_forward
