Given the quadrant of q in standard position and a trigonometric function value of q , find the exact value for the indicated function. II, sin q = 0.4; sec q

9514 1404 393

  -(5/21)√21

Step-by-step explanation:

In the second quadrant, the cosine and secant are negative, so the value of interest is ...

  sec(q) = -1/√(1 -0.4²) = -1/√0.84 = -√(25/21)

  sec(q) = (-5√21)/21

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

4+4+2x

or

2x+8
