A population of mice is increasing exponentially. On Monday there were 120 mice. One month later there were 132 mice. Write a fu
den301095 [7]

Answer:

y =120*1.1^x

r = 10\% --- Percentage increase

Step-by-step explanation:

Given

Let

x \to months

y \to mice

So, we have:

(x_1,y_1) = (0,120) --- Monday

(x_2,y_2) = (1,132) --- One month later

Required

The function

The function is represented as:

y = ab^x

In (x_1,y_1) = (0,120), we have:

120 =a * 1

120 =a

Rewrite as:

a = 120

In (x_2,y_2) = (1,132), we have:

132 = a * b^1

132 = a * b

Substitute a = 120

132 = 120 * b

Solve for b

b = \frac{132}{120}

b = 1.1

Recall that:

y = ab^x

Hence, the function is:

y =120*1.1^x

To get the monthly percentage increase (r), we have:

y = a(1 + r)^x

Compare to: y = ab^x

So:

1+r =b

Make r the subject

r = b-1

r = 1.1-1

r = 0.1

Express as percentage

r = 0.1*100\%

r = 10\%
