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[tex]f(x)=62+35log(x-4)[/tex], where x represents the girl's age (from 5 to 15) andf(x) represents the percentage of her adult heightA) When age =5, we have x=5[tex]f(5) = 62+35log(5-4) = 62+35log 1\\= 62+0 =62[/tex]So height when age is 5 is 62 %B) The approximate of her adult height is [tex]\frac{100}{62} \\=161.29%[/tex]
