World annual natural gas productionl, N , in billion cubic meters, is approximated by N : 2711 + 7715, where t is in years since 2004. (a) How much natural gas was produced in 2004? In 2013'? Gas produced in 2013 : billion cubic meters. Gas produced in 2004 : |:]billion cubic meters. (b) Estimate the total amount of natural gas produced during the 10year period from 2004 to 2014. Total gas produced from 2004 to 2014 =:] billion cubic meters. The following figure shows the velocity, in cm/sec, of a particle moving along a number line. (Positive velocities represent movement to the right; negative velocities to the left.) + t v(t) 8 -7 Find the change in position and total distance traveled between times t = 0 and t = 8 seconds. The change in position is i cm to the The total distance traveled is cm. eTextbook and MediaWater is pumped out of a holding tank at a rate of 7 Tie0'1" liters /minute, where t is in minutes since the pump is started. If the holding tank contains 1000 liters of water when the pump is started, how much water does it hold one hour later? NOTE: Round your answer to one decimal place. In one hour there will be :] liters of water in the tank
