Secret messages can be encoded by using a code and an encoding matrix. If we have the code: 
and an encoding matrix: E = 
, we can encode a message by taking every two letters of the message, converting them to their corresponding numbers, creating a 
/> matrix, and then multiplying each two numbers by E. Use the code and encoding scheme above and an additional encoding matrix, F = 
, to answer the question.If the letters to be encoded are L = 
, show that (E + F)L = EL + FL.

Solve the problem.The table shows the number of new cases (in thousands) of a certain disease diagnosed in a country in various years. 
Let f(t) be the number of new cases (in thousands) of the disease diagnosed at t years since 2010. Suppose that you wish to model f using a quadratic equation. What is the vertex of the model? What does it mean in this situation?
A. (3, 39.3); the smallest number of new cases diagnosed was 39,300 in the year 2013 B. (0, 49.4); the largest number of new cases diagnosed was 49,400 in the year 2010 C. (0, 39.3); the smallest number of new cases diagnosed was 39,300 in the year 2010 D. (7, 45.7); the largest number of new cases diagnosed was 45,700 in the year 2017
