Roger Penrose constructed two tiles that can be used to cover the plane only in aperiodic ways. One tile is called a kite, one is called a dart. Show how to construct a tiling using these tiles. Notice that each tile contains both a blue and red arc. The only rule for assembling the tiles is that the ends of blue arcs must touch only the ends of other blue arcs and ends of red arcs must touch only the ends of other red arcs. Given this rule and using many copies of the kites and darts, show how to construct a tiling using these two tiles.

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
