A total of $30,000 is invested in two corporate bonds that pay 5.5% and 6.25% simple interest. the investor wants an annual inte
lubasha [3.4K]

Answer:

  $10,000

Step-by-step explanation:

Let x represent the amount invested in the 5.5% bond.

For an annual income of $1800, we want ...

  (5.5%)x + (6.25%)(30,000-x) = 1800

  (-0.75%)x + 1875 = 1800

  -0.0075x = -75 . . . . . . . . . subtract 1875

  x = 10,000 . . . . . . . . . . . . . divide by -0.0075

At most $10,000 should be invested at 5.5% to obtain at least $1800 in interest.

Find the given elements of matrix D<br> Please help!!!
TEA [102]

Answer:

Element wise subtraction.

Step-by-step explanation:

Matrix Subtraction is done element wise.

Therefore, D = \[  \left[ {\begin{array}{ccc}   3 & 1 & 0 \\   -1 & 2 & 4 \\9 & 7 & -2  \end{array} } \right]\] - \[  \left[ {\begin{array}{ccc}   5 & 2 & -4\\   1 & 12 & 3 \\ 11 & 3 & -2  \end{array} } \right]\]

This becomes:

\[   D =  \left[ {\begin{array}{ccc}   -2 & -1 & 4 \\    -2 & -10 & 1 \\    -2 & 4 & 0  \end{array} } \right]\]

Now, $ d_{11} = -2 $

$ d_{12} = -1 $

$ d_{13} = 4 $

$ d_{21} = -2 $

$ d_{22} =  -10 $

$ d_{31} = -2 $
