The table shows the number of bacteria in a petri dish over a three hour period. Write an exponential function to represent the number of bacteria in the petri dish as a function of time.

1380/460=3  4140/1380=3  12420/4140=3 f(x)=460*3x

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

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
