Answer:

The value of f(2) would be -40.

Step-by-step explanation:

Given function is,

$f(x) = 2x^3 - 3x^2 - 18x - 8$

Substituting x = 2 in the above function,

We get,

$f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8$

$=2(8) - 3(4) - 36 - 8$

$=16 - 12 - 44$

$\implies f(2)= -40$

Hence, the value of f(2) would be -40.

$tan = \frac{opp}{adj} = \frac{x}{24}$

$\tan(62) = \frac{x}{24}$

$x = 24 \tan(62)$

$x = 45.1374351683$

$x = 45.14$
