The expression 36x² - 121 is in the 'difference of two squares form' which is (a² - b²)
Factorising (a² - b²) gives (a+b)(a-b)
Factorising 36x² - 121 gives (6x+11)(6x-11)
The answer is 4
Because 0.5 times 4 is 2
-4 is less than -5 even though they are both on the same side of the number line. -4 is closer to zero.
The shape of the cross-section formed is a triangle, when a cone is cut in such a way that the cross-section is perpendicular to the base and it passes through the vertex.
Answer:
False
Step-by-step explanation:
At any X point, there should be only one Y point. So at X=1, function should intercept Y axis only at a single point, whereas this graph intercepts it two times. It is not a function, but it is a graph.
