Please helpp with qn6, thanks

6i) 1584π

ii) 1700cm

Step-by-step explanation:

Please see the attached pictures for full solution.

Clarification:

In the 2nd image, in the 2nd and 5th line, the volume of 8 spheres and volume of 1 sphere refers to the amount of material used in 8 spheres and 1 sphere respectively.

Since the cylinder is melted and recasted into the spheres, the total volume (amount) of material in the cylinder would be equivalent to the total amount of material in 8 spheres.

just get this app called photo math it should be able to do those

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
