Nutrition Suppose the weights (in grams) and lengths (in centimeters) of three groups of laboratory animals are given by matrix A, where column 1 gives the lengths and each row corresponds to one group.
A=[12.525011.82159.8190]
If the increase in both weight and length over the next 2 weeks in 20% for group I, 7% for group II, and 0% for group III, then the increases in the measures during the 2 weeks can be found by computing GA, where
G=[0.200000.070000]
What are the increases in respective weights and measures at the end of these 2 weeks?
Find the matrix that gives the new weights and measures at the end of this period by computing
(I+G)A
Where I is the 3×3 identity matrix.
