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, $d_{11} = -2$

$d_{12} = -1$

$d_{13} = 4$

$d_{21} = -2$

$d_{22} = -10$

$d_{31} = -2$
