Please explain how I can use math to solve the problem.
Sarah drops a penny from a height of 1250 feet. I will be using h for height and t for time in seconds, this will be modeled in the function h = 16t^2 + 1250. How will it take for Sarah’s penny to reach the ground?
How I would do it is get this "Sarah" to drop the penny again so I can just count how long it takes. But I have to use "Math" to solve it. How do I use "Math" to solve it?
Explain, PLEASE NO DIRECT ANSWER I WANT TO LEARN

Best ResponseYou've already chosen the best response.2First, we are going to have to multiply 16 ^2

Best ResponseYou've already chosen the best response.2Thats it we have to solve 16^2. You know how if noti will show you how.

Best ResponseYou've already chosen the best response.0So do you 16 * 2 thats easy

Best ResponseYou've already chosen the best response.2K what did u get

geekfromthefutur

Best ResponseYou've already chosen the best response.2ok do it with a negative 16

geekfromthefutur

Best ResponseYou've already chosen the best response.2Ok so now we have to do this 32t + 1250 now solve that

Best ResponseYou've already chosen the best response.0Why do we have t all the sudden?

geekfromthefutur
 one year ago
Best ResponseYou've already chosen the best response.2the t has been there lol h = 16t^2 + 1250.

geekfromthefutur

Best ResponseYou've already chosen the best response.2and you are correct

Best ResponseYou've already chosen the best response.0I know that but why are we multiplying it with 1218t?

Best ResponseYou've already chosen the best response.0I still will need to show how I came up with the answer and I dont want it as a "direct answer"

Best ResponseYou've already chosen the best response.2Ok well lets see first you mutiply 16 x 2 and you get 32t

geekfromthefutur
 one year ago
Best ResponseYou've already chosen the best response.2So then, The total seconds it fallen was 32 seconds. Because when you mutiply 16*2 it will give u 32 and with the 1250 it was already part of the problem so the only thing needed to be done was mutiplication and solving 16*2

geekfromthefutur

Best ResponseYou've already chosen the best response.2T IS 32 lol sry caps

anonymous

Best ResponseYou've already chosen the best response.0That is slow falling that cant be right

geekfromthefutur

Best ResponseYou've already chosen the best response.2@satellite73 Is this correct

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Well I guess with the wind pushing the penny up making the fall slower

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0if it is correct then all I have to do is times 32 by 1250 that will give me how much time it takes from top to bottom

geekfromthefutur

Best ResponseYou've already chosen the best response.2THATS WHAT I FORGOT TO DO DA* IM DUM

anonymous

Best ResponseYou've already chosen the best response.0Wait you didn't think to times 32 by 1250?

geekfromthefutur
 one year ago
Best ResponseYou've already chosen the best response.2No because it you mutiplied it would be to high of a nimber so we have to divide the time

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Ok... If you say so. Go on

geekfromthefutur
 one year ago
Best ResponseYou've already chosen the best response.2So now how would u do it 32/1250 or 1250/32?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.032/1250 would be way to small of a number but why would we 1250/32

geekfromthefutur

Best ResponseYou've already chosen the best response.2Exactly and what would we get and sorry the site got closed down

anonymous

Best ResponseYou've already chosen the best response.0I didn't notice anything and we would get 39.06

geekfromthefutur
 one year ago
Best ResponseYou've already chosen the best response.2So thats what it would be

geekfromthefutur
 one year ago
Best ResponseYou've already chosen the best response.2Yes ik im right

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0K so now we times that by 1250 to find the total time from top to bottom

geekfromthefutur
 one year ago
Best ResponseYou've already chosen the best response.2Now what do you think?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0I think that t = 39. and the total time from top to bottom is 48828

anonymous

Best ResponseYou've already chosen the best response.0Thanks I just need to put this down in steps and explain it step by step!
