Answer:
3
Step-by-step explanation:
3 is the coefficient of c as it is a constant, whereas a and b are variables, subject to change.
Answer:

Step-by-step explanation:
Given
-- Rate
-- Principal
-- Time
Required
Determine the compound interest
First, we calculate the Amount (A)


Express % as decimal



The compound interest (C) is then calculated as:
i.e. Amount - Principal


Answer:
the slope -3, slope meaning rate of change and y intercept is 1.
hope that answers your question
(used desmos to graph, good stuff!!!)
Using an exponential function, it is found that there will be 32,866 pigeons in 13 years.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
The initial value and the growth rate are given by:
A(0) = 9520, r = 0.1.
Hence the function is given by:

Hence in 13 years, the amount of pigeons will be of:

80p=pr^2+p(2r)^2
80p=pr^2+4pr^2
80=r^2+4r^2
80=5r^2
16=r^2
r=4 for the smaller circle´s radius, and 8 is the larger circle´s radius.
Have a nice day, I hope this was helpful :D
