Alright so, = 1/(4-0) ∫ x√(1+2x) dx u = 1+2x du = 2 dx 1/2 du = x = 1/4 [ (u-1)/2 (u)^(1/2) (2)] du = 1/4 [ u^(3/2) - u^(1/2)] du = 1/4 [ (2/5)(1+2x)^(5/2) - (2/3)(1+2x)^(3/2)] = (1/10)(1+2x)^(5/2) - (1/6)(1+2x)^(3/2) + C Then, [ ∫b -∫a] 198/10 +
density (p)= m/V V= m/p V Al = ? m Al = 2000g p Al = 2.70g/cm3 Plug info into this equation: V= m/p and you should get 740.74 cm3 as the volume.
