Answer:

$x=\frac{\pi }{6} ,\frac{7\pi }{6}$

Step-by-step explanation:

$3*cot^2x-1=0\\\\3*cot^2x=1\\\\cot^2x=\frac{1}{3} \\\\cot(x)=\sqrt{\frac{1}{3} } \\\\cot(x)=\frac{1}{\sqrt{3} } \\\\\frac{1}{tan(x)}=\frac{1}{\sqrt{3} } \\\\tan(x)=\sqrt{3} \\$

x=tan^-1( $\sqrt{3}$ )

It has to be in Quadrant 1 $\frac{+}{+} =+$ or 3 $\frac{-}{-}=+$ for positive.

$x=\frac{\pi }{6} ,\frac{7\pi }{6}$

Unless that incorrect due to tan(x) range is $-\frac{\pi }{2} \leq x\leq \frac{\pi }{2}$ . Then the only answer is $x=\frac{\pi }{6}$

Answer:

2.56

Step-by-step explanation:

Multiply by (1+6e^(-.7t))/1000:

2000/1000 = 1 +6e^(-0.07t)

1 = 6e^(-0.07t) . . . . . . . . . subtract 1

e^(0.07t) = 6 . . . . . . . . . . multiply by e^(0.07t)

0.07t = ln(6) . . . . . . . . . take the natural log

t = ln(6)/0.07 . . . . . . . divide by the coefficient of t

t ≈ 2.55966 ≈ 2.56
