A population of 249 birds increases at a rate of 16% annually. jewel writes and exponential function of the form f(x)=abc to represent the number of birds after x years. Which values should she use for a and b

a = 249 and b = 1.16

Step-by-step explanation:

Consider the provided information.

The exponential function for growth is:  

Here, a is the initial value and r is the rate of change.

It is given that the number of birds is 249.

It means a = 249

The rate is given 16%

r=0.16

Put the value of a and r in the above formula.

Now we will compare it with the exponential function form

Therefore, a = 249 and b = 1.16

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320

no solution exists the way you wrote the equation.
