Answer:

Figure A)

Step-by-step explanation:

Line symmetry :  A line of symmetry refers to the line that divides a figure into two mirror images.

Rotational symmetry : If a shape or pattern can be rotated around a central point and remains the same, then in that case we say that it has a rotational symmetry .

In figure A),

It is a parallelogram and a parallelogram has rotational symmetry of 180º i.e order 2

Also, in figure A),

it has line of symmetry , see figure (i) .Arrow in the figure represents the line of symmetry, so this figure also has line symmetry .

What two steps are necessary to put this equation into standard form?
ivanzaharov [21]

Answer:

A. Add 4 to both sides and subtract 6x from both sides

Step-by-step explanation:

The correct expression is

x^2-3x+16=6x-4

Add 4 to both sides and subtract 6x from both sides

Add 4 to both sides

x^2-3x+16+4=6x-4+4

x^2-3x+20=6x

Subtract 6x from both sides

x^2-3x-6x+20=6x-6x

x^2-9x+20=0

A restaurant orders corn tortillas and flour tortillas. The ratio of the number of corn tortillas to flour tortillas is 3:4. Wha
Natalija [7]

4:7

Step-by-step explanation:

The ratio of the number of corn tortillas to flour tortillas is 3:4. So this means there are at least 3 corn tortillas and 4 flour tortillas.

We need to add 3 and 4 to see the simplified total of tortillas. 3+4=7.

There is a total of 7 tortillas regardless of their type.

Now we just need to compare this with the number they already gave us for flour tortillas, which is 4.

4:7 or 4 flour:7 in total

The ratio of flour tortillas to total tortillas is 4:7.

T(v) = Av represents the linear transformation T. Find a basis for the kernel of T and the range of T.
lawyer [7]

Answer:

Ker(T) has basis \emptyset

Range(T) has basis \left\{\left(\begin{array}{c}2&3\end{array}\right), \left(\begin{array}{c}1&4\end{array}\right) \right\}.

Step-by-step explanation:

If the matrix you wanted to represent  is A=\left(\begin{array}{cc}2&1\\3&4\end{array}\right), then:

ker(T)=\left\{{\bf x}\in \mathbb{R}^{2}: A{\bf x}=0\right\}.

So, to find ker(T) you must solve the homogenous equation

A{\bf x}=\left(\begin{array}{cc}2&1\\3&4\end{array}\right) \left(\begin{array}{c} x&y \end{array}\right)=\left(\begin{array}{c}0&0\end{array}\right)

Using Gauss elimination we obtain the simpler equivalent system

\left(\begin{array}{cc} -6&3\\0&5\end{array}\right) \left(\begin{array}{c} x&y\end{array}\right)=\left(\begin{array}{c}0&0\end{array}\right)

Then, we have that

x=0,y=0.

We have that ker(T)=\{\left(\begin{array}{c}0&0\end{array}\right)\}. On this case we say that the basis is the empty set \emptyset.

The range of T is the set of vectors of the form

\left(\begin{array}{c} \alpha &\beta\end{array}\right)=\left(\begin{array}{cc}2&1\\3&4\end{array}\right)\left(\begin{array}{c}x&y\end{array}\right)=x\left(\begin{array}{c}2&3\end{array}\right)+y\left(\begin{array}{c}1&4\end{array}\right)

So,

Range(T)=\langle \left(\begin{array}{c}2&3\end{array}\right), \left(\begin{array}{c}1&4\end{array}\right) \rangle. Where the angle brakets denotes the span.
