An isometric transformation is applied to a trapezoid to create a parallelogram. What is the length of JK? 6 cm 7 cm 10 cm 13 cm

Answer:

C). 10 cm

Step-by-step explanation:

A Trapezoid is characterized as a quadrilateral having two parallel(non-adjacent) sides. While an isometric transformation includes a geometric system having three equal axes lying at right angles to one another. In order to convert the trapezoid into a parallelogram, the length of JK must be 10cm(8 + 2) so that opposite edges are of equal length with an angle of 90°. Thus, <u>option C</u> is the correct answer.

Use the following paycheck to answer the question.
Katyanochek1 [597]

The deductions account for 18.724% of Zachary's paycheck.

Step-by-step explanation:

Step 1; Zachary is supposed to get a paycheck for $20,160.00 but instead, he receives a lesser amount of money due to deductions. The money he receives after deductions is $16,385.31.

Money deducted = Original paycheck amount - deductions = $20,160.00 - $16,385.31 = $3,774.69.

So Zachary gets a deduction of $3,774.69

Step 2; To calculate the percent of deductions in terms of his pay we divide the deduction cost with the original paycheck amount and multiply it by a 100 to convert it into a percentage.

Deduction % = ($3,774.69 / $20,160.00) × 100 = 0.1872366 × 100 = 18.72366%

Rounding this off, we get the deduction % as 18.724%.

Determine if the matrix below is invertible. Use as few calculations as possible. Justify your answer.
Marysya12 [62]

Answer:

This shows 3 pivot position matrixes.

Step-by-step explanation:

The given matrix is:  

\left[\begin{array}{ccc}1&-2&-5\\0&4&3\\-3&3&0\end{array}\right]

The option D is correct for this matrix.

The matrix is invertible and the given matrix has 3 pivot positions.

The matrix is invertible if its determinant is nonzero.

Multiply the 3rd row by 1/3.we get:

\left[\begin{array}{ccc}1&-2&-5\\0&4&3\\-1&1&0\end{array}\right]

Now, add the first row with third row:

\left[\begin{array}{ccc}0&-1&-5\\0&4&3\\-1&1&0\end{array}\right]

Replace third row by first row:

\left[\begin{array}{ccc}-1&1&0\\0&4&3\\0&-1&-5\end{array}\right]

This shows 3 pivot position matrixes.

Hence, a matrix is invertible and has 3 pivot positions.
