Answer:
Step-by-step explanation:
sum of roots β+nβ=-b/a
(n+1)β=-b/a
squaring
(n+1)²β²=b²/a²
product of roots β×nβ=c/a
nβ²=c/a
β²=c/na
∴(n+1)²c/na=b²/a²
multiply by na²
(n+1)²ac=nb²
Answer:
8 games to get $200
Step-by-step explanation:
4x25=100
so just double it to get exactly 200
8x25=200
Dy / dx = - Pi sin (Pix), so dy = - Pi sin (Pix) dx, for x = 1/3, and dx = -0.2
we get dy = - Pi x sin Pi/3 x (-0.2) = 3.14 x 0.2 x 0.86=0.543
