BlackZzzverrR [31]

Answer:

62% and 161.29%

Step-by-step explanation:

Given that the percentage of adult height attained by girls who are x years old can be modeled by

$f(x)=62+35log(x-4)$ , where

x represents the girl's age (from 5 to 15) and

f(x) represents the percentage of her adult height

A) When age =5, we have x=5

$f(5) = 62+35log(5-4) = 62+35log 1\\= 62+0 =62$

So height when age is 5 is 62 %

B) The approximate of her adult height is

$\frac{100}{62} \\=161.29%$
