Assume the Ziders continue to grow in the same pattern. How old would a Zider be that had 73 hairs?

Number of hairs in day 1 , a = 5.

Every day number of hairs increases by , d = 4.

So, it is an Arithmetic Progression with first term a = 5 and common difference d = 4.

So, number of hair in nth days is given by :

Let, after x days number of hairs are 73.

Therefore, Zider is 18 days old.

Hence, this is the required solution.

answer is : muchas/tipicas

have a nice day!

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
