Afilm set designer is using white and colored tiles in a pattern to create paths of different lengths. if x is the length of the path in feet, the number of colored tiles needed to make it is calculated using the rule
(8x2y2)(3xy)
where y represents the number of white tiles.
which simplified expression represents the number of colored tiles used for a path of length x feet?
• 24x3y3
• 11x3y3
• 24x2y2
• 11x2y2

Ответ:
(8x2y2)(3xy)
24x3y3. So the correct answer would be the first option.
Hope this answer helps. Thanks for posting your question.
Ответ:
a) (-2,-6)
b) (3, -5)
c) (3 ,2)
d) (8,-9)
Step-by-step explanation:
a) You have to use the Rotation Matrix, which is
and it has to be multiplied by (x,y) which is equal to (2,6)
Then after the multiplication you´ll obtain (-2,-6)
b) You have to use the Rotation Matrix which is
and multiplied for the vector (5,3) you´ll obtain (3, -5)
c) The Rotation Matrix for a rotation of 90° is given by
and again after the multiplication you´ll obtain (3,2)
d) The Rotation Matrix is given by
hence after the multiplication fo the roation matrix and the vector you´ll obtain (8,-9)
The answer of 5 and 6 is the matrix that I already wrote down on the excercises.
