5. two points are 10 units apart on the coordinate plane. if

an ant were to walk between the 2 points moving only

vertically and horizontally, it would have to walk 6 horizontal

units. how many vertical units would the ant have to walk?

8

Step-by-step explanation:

Let's say the ant is walking across the floor. Then it hits the wall and starts climbing to the ceiling.

We have a right triangle, as in the diagram, so we can apply Pythagoras' Theorem.

x² +  6² = 10²

x² + 36 = 100

       x² =  64

        x =     8

The ant must walk eight vertical units.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

∡ eia and ∡ kij are congruent
