Find the given elements of matrix D 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, $d_{11} = -2$

$d_{12} = -1$

$d_{13} = 4$

$d_{21} = -2$

$d_{22} = -10$

$d_{31} = -2$

Erik drives 19.2 miles in 16 minutes.

Katen [24]

Answer:

Erik's average speed exceeds the speed limit by 6.91 miles per hour.

Step-by-step explanation:

Let suppose that Erik travels at constant speed. Hence, the speed ( $v$ ), measured in miles per hour, is determined by following equation of motion:

$v = \frac{s}{t}$ (1)

Where:

$s$ - Distance, measured in miles.

$t$ - Time, measured in hours.

Please notice that a hour equals 60 minutes. If we know that $s = 19.2\,mi$ and $t = 0.267\,h$ , then the speed of Erik is:

$v = \frac{19.2\,mi}{0.267\,h}$

$v = 71.910\,\frac{mi}{h}$

Which is 6.91 miles per hour above the speed limit.
