A stone is dropped into a lake, creating a circular ripple that travels outward at a speed of 60 cmys.(a)Express the radius r of this circle as a function of the time t (in seconds).(b)If A is the area of this circle as a function of the radius, find A8r and interpret it.

the answer is the third / last answer

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

how many friends does he have? i think some of the information got cut off in the problem.
