As, v=√2as
Squaring both sides,
v²=2as
∴ s= v²/2a
Do u have an attachment?? :)
Answer:
is the size of the square
Step-by-step explanation:
Let the side of the square cut from the cardboard be “x”
Size of the square base =
, height of the box = x
Volume of square box = Area * height =
Differentiating the above equation and equating it to zero, we get –
d/dx
d/dx
= d/dx
d/dx
On solving above equation, we get –
Use this formula a2 − b2 = (a + b)(a − b)
<span>(x+1)^2-(x-1)^2 in this case, a = x+1, b = x-1</span>
<span>= [(x+1) + (x-1)] * [(x+1) – (x-1)]</span>
=(x +1 + x – 1) *(x +1 – x +1)
= 2x * 2
<span>=4x</span>
