uysha [10]

Answer:

2.86 miles.

Step-by-step explanation:

We have been given that Megan uses a pedometer to find how many steps she takes each school day. she took 32,410 steps over the course of 5 days.

\text{Steps per day}=\frac{32410}{5}

\text{Steps per day}=6482

\text{Inches in 6482 steps}=6482\times 28

\text{Inches in 6482 steps}=181496

1 feet = 12 inches.

\text{Feet in 6482 steps}=\frac{181496}{12}

\text{Feet in 6482 steps}=15124.666666

\text{Miles in 6482 steps}=\frac{15124.666666}{5280}

\text{Miles in 6482 steps}=2.8645

\text{Miles in 6482 steps}\approx 2.86

Therefore, Megan walks 2.86 miles on Monday.

K = [ 14 -13 0 3 8 -1 -10 -2 5 ] find the determinant of K
spin [16.1K]

I suppose <em>K</em> is the matrix

K = \begin{bmatrix}14 & -13 & 0 \\ 3 & 8 & -1 \\ -10 & -2 & 5\end{bmatrix}

To compute det(<em>K</em>), you can use a simple cofactor expansion along the first row:

\det(K) = 14\times\det\begin{bmatrix}8 & -1 \\-2 & 5\end{bmatrix} - (-13)\times\det\begin{bmatrix}3 & -1 \\ -10 & 5\end{bmatrix} + 0\times\det\begin{bmatrix}3 & 8 \\ -10 & -2\end{bmatrix} \\\\ \det(K) = 14\times(8\times5-(-1)\times(-2)) + 13\times(3\times5-(-1)\times(-10)) + 0 \\\\ \det(K) = 14\times38 + 13\times5 = \boxed{597}
