mass of a solid is= 1.3kg tension of a solid =1.3*10=13N tension of the spring=6.0N since is completely immersed in water the upthrust in the solid= tension of a solid- tension of the spring U=13-6=7N
x²+4x+4=(x+2)(x+2) x³+8=(x+2)(x²-2x+4) (x²+4x+4)/(x³+8)= (x+2)(x+2)/(x+2)(x²-2x+4) (x+2)/(x²-2x+4) Lim((x²+4x+4)/(x³+8)) = Lim((x+2)/(x²-2x+4))= (-2+2)/((-2)²-2(-2)+4)=0/4=0 Hence Lim((x²+4x+4)/(x³+8)) as x approaches - 2 from the right =0
