please help me i will fan and medal The function H(t) = −16t2 + 90t + 50 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in the air along a path represented by g(t) = 28 + 48.8t, where g(t) is the height, in feet, of the object from the ground at time t seconds. Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? Part B: Explain what the solution from Part A means in the context of the problem.

look at this https://www.desmos.com/calculator/uqp15udxvy

  • anonymous
how do I use that @IrishBoy123
anonymous
  • anonymous
Use integers 1-4 and make a table. Those integers stand for variable t. Substitute the numbers into the equation for t and solve.

@mackenzieee do u still need help?
anonymous
  • anonymous
yeas please
anonymous
  • anonymous
with the same question?
anonymous
  • anonymous
yes still part a and part b

CRAAAPPPPP
anonymous
  • anonymous
im so sorry
anonymous
  • anonymous
that is my fault
anonymous
  • anonymous
its okay cause I looked at that first as well
anonymous
  • anonymous
you already looked at other openstudy questions?
anonymous
  • anonymous
yes
anonymous
  • anonymous
what grade lvl is this?
anonymous
  • anonymous
im not sure but I know its algebra 1
anonymous
  • anonymous
@welshfella we need help
anonymous
  • anonymous
please help @welshfella
anonymous
  • anonymous
he isn't on rn
anonymous
  • anonymous
i'm so sorry, i can keep trying to figure it out but it might take awhile
anonymous
  • anonymous
that's fine ive been trying to figure it out for 4 hours already take as long as you need
anonymous
  • anonymous
lol well what grade are u taking this is? maybe i just need confidence
anonymous
  • anonymous
7th
anonymous
  • anonymous
omg
anonymous
  • anonymous
yea, i should be able to do this omfg
anonymous
  • anonymous
well this is an high school credit class honors and online so its not easy
anonymous
  • anonymous
ya, ik but ill try my best to help
anonymous
  • anonymous
thank you
anonymous
  • anonymous
np
anonymous
  • anonymous
ok so work with me real quick ok?
anonymous
  • anonymous
okay
anonymous
  • anonymous
so ik you have to replace the intergers but do u know if i replace h or t?
anonymous
  • anonymous
WAIT!!!!!!!
anonymous
  • anonymous
i got it!!!!
anonymous
  • anonymous
omg really
anonymous
  • anonymous
i'm pretty sure
anonymous
  • anonymous
so you see how it says the use numbers 1-4?
anonymous
  • anonymous
yeah
anonymous
  • anonymous
you just replace the T with 1 then solve it, the replace T with 2 and solve it ect.
anonymous
  • anonymous
do u get it?
anonymous
  • anonymous
yeah I get what your saying but ive already done that

  • anonymous
sorry, i had to re post it so i dont keep scrolling up and down
anonymous
  • anonymous
and ok, so what all have you done so far?
anonymous
  • anonymous
just plugged in those number for the equation but didn't find any matches
anonymous
  • anonymous
you have to solve for H once you plug in the numbers

how do you do that? if you solve for h you would also have to slove for g

  • anonymous
ok so now that we have found all the H ones, now we put those in a table
anonymous
  • anonymous
that one doesn't make sense it being false
anonymous
  • anonymous
ok then we know those two aren't the answer right?
anonymous

I guess

ok so which ones from both H and G are either close or similar?
anonymous
  • anonymous
h=2 g=3
anonymous
  • anonymous
those are the closest?
anonymous
  • anonymous
yeah h-2=166 g-3=174.4
anonymous

sorry that i'm taking so long

its okay

  • anonymous
did you graph those answers?
anonymous
  • anonymous
how would you graph that
anonymous
  • anonymous
not graph it but you put it in a table
anonymous
  • anonymous
ill give you an example
anonymous
  • anonymous
|dw:1438807772565:dw|
anonymous
  • anonymous
yes
anonymous
  • anonymous
lol it took me forever
anonymous
  • anonymous
me too so how do I answer that
anonymous
  • anonymous
i would say H(2) is = to G(3) because those are the closest answer
anonymous
  • anonymous
but how do I know
anonymous
  • anonymous
because we solved for each variable for each expression
anonymous
  • anonymous
i'm not 100% sure but i'm going off what i know
anonymous
  • anonymous
so for part a H(2)=g(3) because 166 and 174.4 are the closes in comparison.
anonymous
  • anonymous
yes, that's what i would put
anonymous
  • anonymous
okay and what for part b
anonymous
  • anonymous
the solution from pat a means that it takes 2 second for H too get around the same height as it takes G 3 seconds
anonymous
  • anonymous
something along that line
anonymous
  • anonymous
omg thank you so much I wish I could give you a thousand medals
anonymous
  • anonymous
i'm sorry if it's wrong but that's what i would put if i got that problem
anonymous
  • anonymous
at this point I don't really care its the second to last test I have to take
anonymous
  • anonymous
lol ok well if you ever need help just tag me
