Find and interpret f(70). b. Find and interpret g(70). c. Which function serves as a better model for the chance of surviving to age 70?arrow_forwardAn antique table increases in value according to the function v(x)=550(1.05)x dollars, where x is the number of years after1980 . a. How much was the table worth in 1980 ? b. If the pattern indicated by the function remains valid, what was the value of the table in 1995 ? c. Use a table or a graph to estimate the year when this table will reach double its 1980 value.arrow_forwardPhysicists using the radioactivity equation y = yo e - kt call the number 1 the mean life of a radioactive nucleus. 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
