Hy ;-; masi ingat sy ciapa? :vf(x) = 7x + 12x² – x × x + x/2f(10) = …​

Penjelasan dengan langkah-langkah:

tt{{{f(x) = 7x + 12x² - x × x + frac{x}{2} }}}

tt{{{f(10) = 7(10) + 12(10²) - 10 × 10 + frac{10}{2} }}}

tt{{{f(10) = 7(10) + 12(10×10) - 10 × 10 + frac{10}{2} }}}

tt{{{f(10) = 7(10) + 12(100) - (10 × 10) + frac{10}{2} }}}

tt{{{f(10) = 7(10) + 12(100) - 100 + frac{10}{2} }}}

tt{{{f(10) = 7(10) + (12×100) - 100 + frac{10}{2} }}}

tt{{{f(10) = 7(10) + 1.200 - 100 + frac{10}{2} }}}

tt{{{f(10) = (7 × 10)+ 1.200 - 100 + frac{10}{2} }}}

tt{{{f(10) = 70 + 1.200 - 100 + frac{10}{2} }}}

tt{{{f(10) = 1.270- 100 + frac{10}{2} }}}

tt{{{f(10) = 1.170 + frac{10}{2} }}}

tt{{{f(10) = 1.170 + 5 }}}

ttred{{{f(10) = 1.175}}}

<< Penyelesaian >>

Diketahui :

  • x = 10

Ditanya :

  • f(x) = 7x + 12x² – x × x + x/2 = ??

Dijawab :

  • f(x) = 7x + 12x² – x × x + x/2
  • f(10) = 7(10) + 12(10²) – 10 x 10 + 10/2
  • f(10) = ( 7 x 10 ) + ( 12 x 100 ) – ( 10 x 10 ) + 10/2
  • f(10) = ( 70 ) + ( 1.200 ) – ( 100 ) + 10/2
  • f(10) = 1.270 – 100 + 5
  • f(10) = 1.170 + 5
  • f(10) = 1.175
  • f(10) = 1.175

<< Kesimpulan >>

  • f(x) = 7x + 12x² – x × x + x/2  
  • f(10) = 1.175
