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%

Solve the slope for the table.
Nikitich [7]

Answer:

The slope is 0

Step-by-step explanation:

All y-values are equal to 5 meaning the graph is a straight horizontal line. Slope is the rate at which a graph increases or decreases. Seeing as this graph doesn't do so, the slope is 0.
