Given x =
and y= −4
−2
:
a. find x + and graph the parallelogram that is formed by x, x + and the origin.
b. transform the unit square by multiplying it by the matrix −4
1 −2
and graph the result.
c. what did you find from parts (a) and (b)?
d. what is the area of the parallelogram that is formed by part (a)?
e. what is the determinant of the matrix −4
1 −2

f. based on observation, what can you say about the degenerate parallelograms in part (a) and part (b)?

Zero is the mid point of the line segment

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )

Ive seen this before! the answer is b
