Answer:

trapezoid.

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid = $\frac{1}{2}$ x (sum of the lengths of the parallel sides) x height

Perimeter = sum of lengths of sides of a trapezoid

Find the determinant of the following matrix.

sineoko [7]

Answer:

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

Step-by-step explanation:

Given:

The given matrix is.

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

the determinant of the above matrix is.

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=2\times (-4) - (-3)\times 1$

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-8 - (-3)$

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-8 +3$

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

Therefore, the determinant of the matrix is -5

Solve using the quadratic formula:

timurjin [86]

Answer:

$\boxed{x_1 = \frac{7 + \sqrt{5} }{2} ~~or~~x_2 = \frac{7 - \sqrt{5} }{2} }$

Step-by-step explanation:

$x^2 - 7x + 11 = 0$

$x^2 - 7x = -11$

$(x - \frac{7}{2} )^2 - \frac{49}{4} = -11$

$(x - \frac{7}{2} )^2 = -11 + \frac{49}{4}$

$(x - \frac{7}{2} )^2 = \frac{5}{4}$

$x - \frac{7}{2} = \pm \sqrt{\frac{5}{4}}$

$x = \frac{7 \pm \sqrt{5} }{2}$
