Answer:
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
Answer:
Step-by-step explanation:
r=13in
Perimeter of a circle is 2πr
P=2×22/7×13
P=81.71in.
If it will make 3 revolution then it will have move 3 times it perimeter
3×81.71
245.14in
The distance the wheel will traveled is 245.14in
9514 1404 393
Answer:
10
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. That is, point O is the midpoint of AC. If AO = 5, then OC = 5 and AC = 5+5 = 10.
