Answer:
The girl attained at age 13 has attained 95.4% of adult height.
Step-by-step explanation:
We are given the following in the question:
[tex]f(x)=62+35 \log(x-4)[/tex]
Here, x is the girls age from 5 to 15 and f(x) represents the percentage of her adult height.
We have to approximate percentage of her adult height has a girl attained at age 13.
We put x = 13 in the above equation:
[tex]f(13)=62+35 \log(13-4)\\f(13) = 62+35 \log(9)\\f(13) = 95.4[/tex]
Thus, a girl attained at age 13 has attained 95.4% of adult height.
At age of 13 , girl attained 95.4 % of her adult height.
Since, The percentage of adult height attained by a girl is represented by a function.
where x represents the girl age.
[tex]f(x)=62+35log(x-4)[/tex]
To find percentage of her adult height has a girl attained at age 13
Substitute x= 13 in above equation.
[tex]f(13)=62+35log9\\\\f(13)=62+33.39\\\\f(13)=95.39[/tex]
Therefore, At age of 13 , girl attained 95.4 % of her adult height.
