Step-by-step explanation:

{x}^{3 }  - 8 {x}^{2}  - 2x + 16 \\  =  {x}^{2} (x - 8) - 2(x - 8) \\  = (x - 8)( {x}^{2}  - 2) \\  = (x - 8)( {x}^{2}  -  { \sqrt{2} }^{2} )  \\  = (x - 8)(x +  \sqrt{2} )(x -  \sqrt{2} )

maxonik [38]

Answer:

50%: day 13

100%: day 26

Step-by-step explanation:

We are given two days and the amount of the moon that is illuminated. The two days are points on a straight line.

(1, 0.02), (2, 0.06)

y = mx + b

m = (0.06 - 0.02)/(2 - 1) = 0.04

y = 0.04x + b

0.02 = 0.04(1) + b

b = -0.02

y = 0.04x - 0.02

We want y = 50% = 0.5

0.04x - 0.02 = 0.5

0.04x = 0.52

x = 13

y = 100% = 1

0.04x - 0.02 = 1

0.04x = 1.02

x = 25.5
