Calculusf(x):If its an equilateral triangle, dat means all d sides ae equal. Taking one side of d triangle, u will have d adjascent side as 12, d hypotenuse as 24, while d oder side is unknown. Let it b y. Using pathagoreas theorem 24^2 - 12^2=576-144 =sqrt(432)=12surd(3). Therefore d centre of gravity will be 12surd(3)/2 =6surd(3). D ans is 6surd(3) |

Mr Calculus: I really need ur help hear guys.I ave tried half way, let me post dis 1 first, still trying harder 4rm laws of indices x * x=x^2 So x^(a^2 b^-1 c^-1)+(a^-1 b^2 c^-1)+(a^-1 b^-1 c^2) Bring all d ^-1 nd ^2 2geda x^(a^2(bc)^-1)+((ab)^-1 b^2)+((ab)^-1 c^2) x^(a^2+b^2+c^2)(ab+bc+ac)^-1 Am still solving 4 d final ans |

Boladearo: (81^1/log3) / (36^1/log6). The logs are in base 2.If its 81^1/(log3)/ 36^1(log6) all in base 2 den it will b From laws of logarithn, 1/logb base a=loga base b So we ave 81^log2 base 3/ 36^log2 base 6 3^4log2 base3/ 6^2log2 base 6 But b^ylogx bseb=ylogx baseb=logx^y baseb 3^log2^4 bsae3/6^log2^2 base6 4rm laws of log a^logb base a=b 2^4/2^2=16/4 =4 1 Like |

oladoya: oga talk say make we no use dat word again, u no dey hearOladoya, pls u ae wrong........my boss mathefaro nd mr calculus ae right. U cn still solve it dis way x^2=4x, d.b.s by x U will ave x=4 OR x^2=4x x^2 - 4x + 0=0 Factorise using general quadratic formula, u will have x=4 or x=0 Therefore x=4. |

labodinho: yea,i jst got dah,kan u n @ all check on these....(1)solve the equation _/x+7=x-5 (2).....Let Y=4x+3/2x-5,write x as a function of y. (3).....If dy/dx=6xrtp2 + 15xrtp4 and y=7 when x=2.Find y N.B:rtp=rays to power....tanx3). dy/dx=6x^2 + 15x^4 dy=(6x^2 + 15x^4)dx Integrating both sides, you will have note:integratind dy=y So y=6x^3/3 + 15x^5/5 y=2x^3 + 3x^5 But y=7 nd x=2 So 2x^3 + 3x^5 - y=0 2(2)^3 + 3(2)^5 - 7=0 All=105 Therefore y= 2x^3 + 3x^5 +105 |

Mr Calculus:Let u=sinx. du/dx=-cosx.........dx=du/-cosx Integtal 7^u dx But dx=du/-cosx Integral 7^u . du/-cosx = 1/-cosx integral 7^u But integral a^x=a^x/lna So 1/-cosx(7^u/ln7) = -(1/cosx)(7^sinx/ln7) =-7^sinx/cosln7 + c |
