MAVERICK [17]

Answer:

1st option is the answer

Step-by-step explanation:

blue line: slope is 1 and y-intercept is 1; therefore equation is y= x + 1

red line: slope is -1 and y-intercept is -3; therefore equation is y= -x - 3

If the circumference of a circle is 201 centimeters what is the radius of the circle (to the nearest whole number)? Use 3.14 for

saul85 [17]

Formula for circumference: C = 2pi*r

This becomes 201 cm = 2(3.14) r

Divide both sides of this eqn by 6.28:

201
------- = r = 32 cm (approx).

What is 120 to 130 kilometers per hour when converted to miles per hour?

viva [34]

1 kilometer = 0.6214 miles

Find a matrix representation of the transformation L(x, y) = (3x + 4y, x − 2y).

mario62 [17]

Answer:

$\left[\begin{array}{cc}x&y\end{array}\right] * \left[\begin{array}{cc}3&1\\4&-2\end{array}\right] = \left[\begin{array}{cc}3x+4y&x-2y\end{array}\right]$

Step-by-step explanation:

The general matrix representation for this transformation would be:

$\left[\begin{array}{cc}x&y\end{array}\right] * A = \left[\begin{array}{cc}3x+4y&x-2y\end{array}\right]$

As the matrix A should have the same amount of rows as columns in the firs matrix and the same amount of columns as the result matrix it should be a 2x2 matrix.

$\left[\begin{array}{cc}x&y\end{array}\right] * \left[\begin{array}{cc}a&b\\c&d\end{array}\right] = \left[\begin{array}{cc}3x+4y&x-2y\end{array}\right]$

Solving the matrix product you have that the members of the result matrix are:

3x+4y = a*x + c*y

x - 2y = b*x + d*y

So the matrix A should be:

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