To calculate: The matrix A that represent the amounts borrowed by each student and matrix B that represent the monthly interest rates.
Answer to Problem 84AYU
The matrices are
Explanation of Solution
Given information:
The amount borrowed by Jamal and Stephanie from two banks for school loan and monthly interest rate of banks are provided below,
Calculation:
Consider the amount borrowed by Jamal and Stephanie from two banks for school loan and monthly interest rate of banks are provided below,
Let matrix A that represent the amounts borrowed by each student and matrix B that represent the monthly interest rates.
So, row 1 of matrix A denote the amount borrowed by Jamal from two banks. And row 2 of matrix Adenote the amount borrowed by Stephanie from two banks. Matrix B will be a column
Therefore,
To calculate: The value of
Answer to Problem 84AYU
The value of
Explanation of Solution
Given information:
The amount borrowed by Jamal and Stephanie from two banks for school loan and monthly interest rate of banks are provided below,
Formula used:
To find the product AB of two matrices A and B, the number of column in matrix A must be equal to number of rows in matrixB.
Calculation:
Consider the amount borrowed by Jamal and Stephanie from two banks for school loan and monthly interest rate of banks are provided below,
Let matrix A that represent the amounts borrowed by each student and matrix B that represent the monthly interest rates.
So, row 1 of matrix A denote the amount borrowed by Jamal from two banks. And row 2 of matrix A denote the amount borrowed by Stephanie from two banks. Matrix B will be a column vector with monthly interest rates provided by banks.
Therefore,
Now,
Monthly compound interest for Jamal is 62 and for Stephanie is
To calculate: The value of
