Urgent….. KalkulusTolong dijawab dengan cara lengkap . Terima kasih
Jawab:
di kerjakan no, 2 dan 3
Penjelasan dengan langkah-langkah:
2) turunan aljabar
sifat :
i) (f ± g)'(x) = f'(x) ± g'(x)
ii). (f . g )'(x) = f' . g + f. g'
iii) ( g/ f}'(x) = { g' f – g f' )/ (f²)
a) (f – g)' (3) = f ' (3) – g'(3) = 2 - (-10)= 12
b) (f. g )'(3) = f' (3) . g(3) + f(3). g'(3) = 2(6) + 7(-10) = 12 – 70 = -58
c) ( g/ f}'(3) = { g'(3) f (3) – g(3) f'(3) )/ (f(3))² = {-10 (7) – 6(2)}/ (7²)
= {-70 – 12} / 49 = – 82/49
3. S= -16t² + 40 t + 100
V = ds/dt
v(t) = -32 t + 40
a) t = 2 –> V2 = -32 (2) + 40 = – 64 + 40 = – 24
b) V =0 ==> 0 = -32t + 40
32t = 40
t = 40/32 = 5/4
