Penjelasan dengan langkah-langkah:
jawabannya 4.374
cara terlampir
• Diketahui :
→ f(p) = 7p × 5p + 19p²
• Ditanya :
→ f(9) = ?
→ f(p) = 7p × 5p + 19p²
→ f(9) = 7(9) × 5(9) + 19(9)²
→ f(9) = ( 7 × 9 ) × 5(9) + 19(9²)
→ f(9) = 63 × 5(9) + 19(9²)
→ f(9) = 63 × ( 5 × 9 ) + 19(9²)
→ f(9) = 63 × 45 + 19(9²)
→ f(9) = 63 × 45 + 19( 9 × 9 )
→ f(9) = 63 × 45 + 19(81)
→ f(9) = 63 × 45 + ( 19 × 81 )
→ f(9) = 63 × 45 + 1.539
→ f(9) = ( 63 × 45 ) + 1.539
→ f(9) = 2.835 + 1.539
→ f(9) = 4.374
→ Jadi, hasil nya adalah 4.374
