- Solve each problem. w is directly proportional to z. If w=-6 when z=2, find w when z=-3.arrow_forwardThe population P (in millions) of Texas from 2001 through 2014 can be approximated by the model P=20.913e0.0184t, where t represents the year, with t=1 corresponding to 2001. According to this model, when will the population reach 32 million?arrow_forwardSolve 5e2x=25. Find the exact answer and then approximate it to three decimal places.arrow_forward
- Repeat the previous exercise to find the formula forthe APY of an account that compounds daily. Usethe results from this and the previous exercise todevelop a function I(n)for the APY of any accountthat compounds n times per year.arrow_forwardThe population of a city is modeled by the equation P(t)=256,114e0.25t where t is measured in years. Ifthe city continues to grow at this rate, haw manyyears will it take for the population to reach onemillion?arrow_forwardFind the intensity of light at a depth of 12 meter if I0=14 and k=0.7. Round to two decimals.arrow_forward
- Use a calculator to help solve each problem. Alcohol absorption In one individual, the percent of alcohol absorbed into the bloodstream after drinking two glasses of wine is given by the following formula. Find the percent of alcohol absorbed into the blood after 12 hour. Pt=0.31-e-0.05t where, t is in minutesarrow_forwardSolve the following equation for x. e 5x = 2 |(Type an exact answer.)
