Question

The graph below compares plant height to the age of the plant. Based on the graph, what is the best prediction of the height of the plant at 5 weeks?

1) 4 inches
2) 5 inches
3) 6 inches
4) 7 inches

Answer 1

The best prediction of the height of the plant at 5 weeks is 6 inches.

Step-by-step explanation:

From the existing graph it is known that the growth formula is y = 1.3x - 0.8.

In the 5th week plant height:

y₅ = 1.3 * 5 - 0.8

= 6.5 - 0.8

= 5.7 rounded to 6 inches

Growth is an increase in the size and number of cells and intercellular tissue, meaning an increase in the physical size and structure of the body in part or in whole, so that it can be measured in units of length and weight.
