Question

what does this graph tell you about the growth of the corn stalk?
growth of corn stalk
height (in.)
(4,25)
time (wk)
in 25 weeks, the stalk grew 4 inches.
the quotient 4/25 is the growth rate of the stalk in inches per week.
the stalk grew at a rate of 6.25 inches per week.
the stalk grew at a greater rate each week.

Explanation:

Step1: Analyze the coordinate point

The graph has a point \((4,25)\) where \(x = 4\) (time in weeks) and \(y=25\) (height in inches).

Step2: Calculate the growth rate

The growth rate \(r\) is given by the formula \(r=\frac{y}{x}\). Substituting \(x = 4\) and \(y = 25\), we get \(r=\frac{25}{4}=6.25\) inches per week.

Answer:

The stalk grew at a rate of \(6.25\) inches per week.
