You are a medical assistant in a pediatrician's office and one of your responsibilities is evaluating the growth of newborns and infants. Your first patient, a baby girl
named Ivy Smith, was 21.5 inches long at 3 months old. At 8 months, you measure
her at 24 inches long. For your medical records, all measurements must be given
both in inches and in centimeters: 1 inch = 2.54 cm
1. Assuming Ivy's growth is linear, find a linear model for her growth (in inches)
over time (in months).
2. Use your model to determine how long Ivy was at birth (in centimeters)? Explain
how you know your answer is correct, assuming this model.
3. Use your model to determine approximately how tall Ivy will be at 1 year old. At
3 years old (in centimeters). Show how you know your answers are correct.
4. Use your model to estimate how old Ivy will be (in years and months) when she
measures at 48 inches. Show how you know your estimate is accurate.
5. Use the chart and table below to plot Ivy Smith's growth, based on the
calculations above (record number 1234.56).1
3. What is Ivy's approximate length-for-age percentile at each of these ages?

PLEASE HELP !!

Step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
