Misc 7 Find the area enclosed by the parabola 4๐‘ฆ=3๐‘ฅ2 and the line 2๐‘ฆ = 3๐‘ฅ + 12 Area ADOEB = โˆซ1_(โˆ’2)^4โ–’ใ€–(3/2 ๐‘ฅ+6) ๐‘‘๐‘ฅใ€— = [3/2 (๐‘ฅ^2/2)+6๐‘ฅ]_(โˆ’2)^4 = [(3๐‘ฅ^2)/4+6๐‘ฅ]_(โˆ’2)^4 = [(3(4^2))/4+6(4)] โ€“ [(3ใ€–(โˆ’2)ใ€—^2)/4+6(โˆ’2)] = [12+24] โ€“ [3โˆ’12] = 36 + 9 = 45 Area required = Area ADOEB โ€“ Area ADOEBC = 45 โ€“ 18 = 27
