Answer:

611 square miles

Step-by-step explanation:

Area of triangle = (1/2)*a*b*sinC (formula when u are not given the height of the triangle, but u are given with the angle.)

= (1/2)*30*47*sin(60°)

= 610.54 square miles (2 d.p)

≈611 square miles (rounded to nearest mile)

The water level, measured in feet above mean sea level, of Lake Lanier in Georgia, USA, during 2012 can be modeled by the functi

FrozenT [24]

Answer:

May 4th, 2012.

Step-by-step explanation:

The highest level can be found with the help of the First Derivative and Second Derivative Tests. First and second derivatives of the function are, respectively:

$l'(t) = 0.04323\cdot t^{2}-0.8354\cdot t +2.703$

$l''(t) = 0.08646\cdot t - 0.8354$

The First Derivative Tests consists on equalizing the first derivative to zero and finding the critical points.

$0.04323\cdot t^{2}-0.8354\cdot t +2.703 = 0$

Roots are $t_{1} \approx 15.672$ and $t_{2} \approx 4.077$ . just the second root offer a realistic solution and is test by the second derivative.

$l''(4.077) = -0.482$ (which leads to a maximum).

Given that a year has 365 days or 12 months, the highest water level occurs at day:

$n = \frac{4.077}{12} \cdot (365\,days)$

$n \approx 124$ (May 4th).
