What happens when the line y x is changed to y x 2?
If you mean: y = x and y = x+2 then the lines are then parallel to each
Why can't the sine of the theta equal 2?
because the ratio of one side of a triangle to the hypotenuse can never be more that one.
What is the intersection of these two lines 2x plus 4 equals y and x - y equals 2?
2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
How many diagonals does a nine sided polygon?
A 9-sided polygon, is named 'Nonagon'. The number of diagonals are '9' From any one node, to the centre of the opposite side. Since there are 9 nodes and 9 lines, then there will be 9 diagonals.
What are the points of intersection of the lines y equals x4 - 2 and y equals x2?
To find points of intersection of any functions, set them equal to each other: x4-2 = x2 x4-x2-2 = 0 factoring this yields: (x2-2)(x2+1)=0 by the zero identity, each of these factors can be set to zero to yield valid solutions: x2-2 = 0 x2 = 2 x = +/- sqrt(2) the second factor, when set equal to zero, yields an imaginary-valued solution. On a normal Cartesian coordinate plane, this means nothing. I assume you are only looking for points of intersection on a normal, real-valued Cartesian coordinate system (the normal x-y coordinate plane used in most elementary math classes). So, these two functions intersect at x = -sqrt(2) and x = sqrt(2)
