ANSWER

C. II, III

EXPLANATION

The secant ratio is negative in the second and third quadrants but positive in the first and fourth quadrants.

The given secant ratio is

$\sec(x) = - 2 = - \frac{2}{1}$

Since the secant ratio is negative, its solution must lie in the third and second quadrant.

The correct answer is C

Solve the equation by completing the square. Round to the nearest hundredth if necessary? X^2+3x=24

Genrish500 [490]

X^2+3x=24, halve the linear coefficient, square it, and add it to both sides

In this case (3/2)^2=2.25

x^2+3x+2.25=26.25 now the left side is a perfect square...

(x+1.5)^2=26.25 take the square root of both sides

x+1.5=±√26.25 subtract 1.5 from both sides

x=-1.5±√26.25

x=-1.5-√26.25 and -1.5+√26.25

x≈ -6.62 and 3.62
