Mr. MD is losing 20% of his hair each year. If he currently has 1,546 hairs on his head, about how many hairs will he have left in ten years? Write a function- What is the initial amount? What is the decay rate? What is the final function? Thank you!

After 10 years, 166 hairs have left on Mr. MD head.

Decay rate is 20 %.

The number of hairs left after n years is given by,

Where P is the current population value, r is rate of decay and n is number of years.

Given that,  

Substitute values in above equation.

Thus, After 10 years, 166 hairs have left on Mr. MD head.

166 hairs

Step-by-step explanation:

Initially he had 1546 hairs. Loses 20% each year. So after 10 years, he will have

= 1546 x 0.80^10

= 1546 x .107374

= 166 hairs

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
