Write your question down!!

how did u get the 2nd equation

Divide both sides by 4.

ok so how do i get t

Use the quadratic formula. You will positive value t approximately 5.05 sec.

will get*

only answers it could be is 3s,4s or 2.2s cuz its one of those riddle papers

Let me check my answer.

i though 4 was h

>.< I don't know why 5 is not among the choices.

im trippen it is 5.1 on here can u tell me how i can get it cuz idk how 2 do dis

5.1 is there and you didn't say that? >.<

yes and i didnt notice till i looked at the riddle paper

:( I redid it like 6 times.

im sorry

can u still help me

lol it's ok.. what is it that you don't understand?

after i get t=-4t^2+20t+1 what do i do

You just solve the equation for t. Are you allowed to use a calculator?

yes

but how u solve 4 t

Okay, you can solve it by your calculator.

i need steps

\[t={-b \pm \sqrt{b^2-4ac} \over 2a}={-20\pm \sqrt{20^2+16} \over -8}\]

or you can just write the equation in your calculator and it will give you the answer directly.

i remember dat fromula but where u get -20 and -8

a=4, b=20, c=1. Plug them in the equation.

okay, then take a=-16, b=80 and c=4. That will work exactly the same.

hmm okay focus now.

ok hold on dis cant go in my calculator when it has the +-

a is the coefficient of t^2, b is the coefficient of t, and c is the constant.

just do it once with the minus, and another time with the plus.

and then take from the two final answers, the positive one.

wat was wrong with the formula they gave me dis is pissing me off

I don't know!

I just told you. can you please help here, at least by reading what I write?

Where exactly is your problem?

i dont know how to use h(t)=-16t^2+vt+c

ook

Good luck!! :)

i keep getteing 50.9 i finally figured out wat u was saying

Good to know that :)

can u help me e 5.1 answer cuz i guess im putting dis in the calculator wrog im not getting 5.1

once i use the formula u gave me is there a step after dat 2 get the 5.1
