Question

baby amelias parents measure her height every month. h(t) models amelias height (in centimeters) when she was t months old. what does the statement h(30)=h(25)+5 mean? choose 1 answer: a the sum of amelias heights at 5 months and 25 months old is equal to her height at 30 months old. b when amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old. c it took amelia 5 months to grow from a height of 25 centimeters to a height of 30 centimeters.

Explanation:

$H(t)$ gives Amelia's height at $t$ months. $H(30)$ is her height at 30 months and $H(25)$ is her height at 25 months. The equation $H(30)=H(25) + 5$ means her height at 30 months is 5 cm more than at 25 months.

Answer:

B. When Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old.
