HELP PLS! A boat is heading towards a lighthouse, whose beacon-light is 102 feet above the water. From point AA, the boat’s crew

KatRina [158]

Answer:

Distance from point AA to point BB = 189.3 feet

Step-by-step explanation:

Let the distance from point AA to the base of the lighthouse be represented by x, and the distance from point BB to the base of the lighthouse be represented by y. So that;

distance from point AA to point BB = x - y

To determine the value of x, applying the required trigonometric function;

Tan θ = $\frac{opposite}{sdjacent}$

Tan 13 = $\frac{102}{x}$

x = $\frac{102}{Tan 13}$

= 441.81 feet

x = 441.8 feet

To determine the value of y;

Tan 22 = $\frac{102}{y}$

y = $\frac{102}{Tan 22}$

= 252.46

y = 252.5 feet

Thus,

distance from point AA to point BB = 441.8 - 252.5

= 189.3 feet

Calculus(Derivatives):

Zigmanuir [339]

$f(x)=x^3+x^2-5x-2$
$\implies f'(x)=3x^2+2x-5=(3x+5)(x-1)$

Critical points occur when $f'(x)=0$ , which happens for $x=-\dfrac53$ and $x=1$ .

Check the sign of the second derivative at each critical point to determine the function's concavity at that point. If it's concave ( $f''(x)$ ), then a maximum occurs; if it's convex ( $f''(x)>0$ ), then a minimum occurs.

You have

$f''(x)=6x+2$

and so

$f''\left(-\dfrac53\right)=-8$
$f''(1)=8>0\implies f(x)\text{ is convex at }x=1$

This means a maximum of $f\left(-\dfrac53\right)=\dfrac{121}{27}$ and a minimum of $f(1)=-5$ .
