How long would it take for an egg dropped from a helicopter to fall 256 feet to the ground? d=16t^2
schepotkina [342]
Well the position function is:

h(t)=-16t^2+256

It will hit the ground when h(t)=0

-16t^2+256=0  factor out -16

-16(t^2-16)=0  factor difference of squares...

L=wh/a(w+p) Make w the subject of the formula​
Anvisha [2.4K]

Answer:

w = lap/ h - la

Step-by-step explanation:

1 Multiply both sides by a(w+p)a(w+p).

la(w+p)=wh

2 Expand.

law+lap=wh

3 Subtract law from both sides.

lap=wh-law

4 Factor out the common term w.

lap=w(h-la)

5 Divide both sides by h-la.

lap/h - la = w

6 Switch sides.

w = lap/ h - la
