H = 3.0 a + 28.2 A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?

h = 34.2 in

Explanation:

h = 3.0a + 28.2

h = height of a girl.

a = age of a girl.

h = 3.0a + 28.2

h = 3.0(2) + 28.2

h = 6 + 28.2

h = 34.2

The estimated height of a 2-year-old girl is 34.2 in.

Hope this helps, thank you :) !!
