a) Write 1x5 matrices C, P, and B that represent the nutritional values of each food.

b) Find C+2P+3B and tell what the entries represent.

Answer 1

Answer:

Explanation:

• a) Given C [ cal pro fat calc sod]

              [140 27 3  13  64]

• P = [cal pro fat calc sod]

     [180 4 11 24 662]

• B = [cal pro fat calc sod]

      [50  5    1  82   20]

To find C+2P+3B = [140 27 3  13  64] + 2[180 4 11 24 662] + 3[50  5    1  82   20]

= [650  54  28  307  1448]

The entries represent skinless chicken breast , One-half cup of potato salad and One broccoli spear.
