Problem:
Use matrix to represent the weight and length
Animal Growth - At the beginning of a laboratory experiment, five baby rats measured. 5.6,6.4,6.9,7.6, and 6.1cm in length, and weighed 144, 138, 149, 152 and 146g, respectively.
a). Write a 2*5 matrix using this information
b). At the end of two weeks, their lengths ( in centimeters) were 10.2, 11.4, 11.4, 12.7, and 10.8 and their weights (in grams) were 196, 196, 225, 250, and 230. Write a 2*5 matrix with this information.
c). Use matrix subtraction and the matrices found in parts a and b to write a matrix that gives the amount of change in length and weight for each rat.
d). During the third week, the rats grew by the amounts shown in the matrix below
length 1.8 1.5 2.3 1.8 2.0
weight 25 22 29 33 20
What were their lengths and weights at the end of this week?
