june is filling her gas tank after 10 seconds her gas has 5 gallons in it. after 25 seconds her gas has 9.5 gallons in it .suppose the amount of gas in the tank depends lineraly on time . \r
\n" ); document.write( "\n" ); document.write( "a ) write an equation describing the gallons of gas in the tang after s seconds.
\n" ); document.write( "4.5 gallons were added in 15 seconds --> 0.3 gallons/sec flow rate
\n" ); document.write( "@ t = 10, g = 5
\n" ); document.write( "10 sec*0.3 gal/sec --> 3 gallons less at t = 0 = 2 gallons
\n" ); document.write( "----------
\n" ); document.write( "g(t) = 2 + 0.3t
\n" ); document.write( "==========================
\n" ); document.write( "b ) how much gaswill be in the tank after 50 seconds
\n" ); document.write( "g(50) = 2 + 0.3*50 = 17 gallons \r
\n" ); document.write( "\n" ); document.write( "c ) what is the y intercept of the equation you found ?
\n" ); document.write( "There is no y, it's g and t for gallons and time.
\n" ); document.write( "The g-intercept (at t=0) is 2.
\n" ); document.write( "-----------------
\n" ); document.write( " What does this number mean in this problem
\n" ); document.write( "It's the # of gallons she had before adding any to the tank.
\n" ); document.write( "
\n" );
