Given the following vector fields and oriented curves C, evaluate integral F * T ds F = <-y, x> on the semicircle r(t) = <4 cos t, 4 sin t>, for 0<= t <= Pi

ds

F = <-y, x> on the semicircle r(t) = <4 cos t, 4 sin t>, for 0<nb

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

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
