Answer:

\underline{ \boxed{f(3) = 41}}

Step-by-step explanation:

if \to \: f(x)=x^3 + 2x^2-x-1 \\ then \: f(3) =  {3}^{3}  + 2( {3)}^{2}  - 3 - 1 \\ f(3) = 27 + 18 - 4 \\ f(3) = 41

Determine the quadrant when the terminal side of the angle lies according to the following conditions: cos (t) &lt; 0, csc (t) &
Bess [88]

Answer:

The angle is in the second quadrant.

Step-by-step explanation:

The cosecant of an angle is the same as the reciprocal of the sine of that angle. In other words, as long as \sin (t) \ne 0,

\displaystyle \csc t = \frac{1}{\sin t}.

Therefore, \csc(t) > 0 is equivalent to \sin (t) > 0.

Consider a unit circle centered at the origin. If the terminal side of angle t intersects the unit circle at point (x,\, y), then

  • \cos (t) = x, and
  • \sin(t) = y.

For angle t,

  • x = \cos(t) < 0, meaning that the intersection is to the left of the y-axis.
  • y = \sin(t) > 0, meaning that the intersection is above the x-axis.

In other words, this intersection is above and to the left of the origin. That corresponds to second quadrant of the cartesian plane.
