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.

1 second -1 2 seconds -2 etc.

- anonymous

where does that come from

- anonymous

can you please help @Haseeb96

- IrishBoy123

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

- anonymous

how do I use that @IrishBoy123

- 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

yeas please

- anonymous

with the same question?

- anonymous

yes still part a and part b

- anonymous

ok ill try

- anonymous

thankyou so much

- anonymous

i have another question that is the exact same thing if u want the link

- anonymous

okay

- anonymous

just scroll to the bottom where ganeshie8 starts talking

- anonymous

@mackenzieee

- anonymous

okay but those are different questions

- anonymous

CRAAAPPPPP

- anonymous

im so sorry

- anonymous

that is my fault

- anonymous

its okay cause I looked at that first as well

- anonymous

you already looked at other openstudy questions?

- anonymous

yes

- anonymous

what grade lvl is this?

- anonymous

im not sure but I know its algebra 1

- anonymous

@welshfella we need help

- anonymous

please help @welshfella

- anonymous

he isn't on rn

- anonymous

i'm so sorry, i can keep trying to figure it out but it might take awhile

- anonymous

that's fine ive been trying to figure it out for 4 hours already take as long as you need

- anonymous

lol well what grade are u taking this is? maybe i just need confidence

- anonymous

7th

- anonymous

omg

- anonymous

yea, i should be able to do this omfg

- anonymous

well this is an high school credit class honors and online so its not easy

- anonymous

ya, ik but ill try my best to help

- anonymous

thank you

- anonymous

np

- anonymous

ok so work with me real quick ok?

- anonymous

okay

- anonymous

so ik you have to replace the intergers but do u know if i replace h or t?

- anonymous

WAIT!!!!!!!

- anonymous

i got it!!!!

- anonymous

omg really

- anonymous

i'm pretty sure

- anonymous

so you see how it says the use numbers 1-4?

- anonymous

yeah

- anonymous

you just replace the T with 1 then solve it, the replace T with 2 and solve it ect.

- anonymous

do u get it?

- anonymous

yeah I get what your saying but ive already done that

- anonymous

- anonymous

sorry, i had to re post it so i dont keep scrolling up and down

- anonymous

and ok, so what all have you done so far?

- anonymous

just plugged in those number for the equation but didn't find any matches

- anonymous

you have to solve for H once you plug in the numbers

- anonymous

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

- anonymous

see ^

- anonymous

ok so now that we have found all the H ones, now we put those in a table

- anonymous

that one doesn't make sense it being false

- anonymous

ok then we know those two aren't the answer right?

- anonymous

I guess

- anonymous

ok so which ones from both H and G are either close or similar?

- anonymous

h=2 g=3

- anonymous

those are the closest?

- anonymous

yeah h-2=166 g-3=174.4

- anonymous

sorry that i'm taking so long

- anonymous

its okay

- anonymous

- anonymous

did you graph those answers?

- anonymous

how would you graph that

- anonymous

not graph it but you put it in a table

- anonymous

ill give you an example

- anonymous

|dw:1438807772565:dw|

- anonymous

yes

- anonymous

lol it took me forever

- anonymous

me too so how do I answer that

- anonymous

i would say H(2) is = to G(3) because those are the closest answer

- anonymous

but how do I know

- anonymous

because we solved for each variable for each expression

- anonymous

i'm not 100% sure but i'm going off what i know

- anonymous

so for part a
H(2)=g(3) because 166 and 174.4 are the closes in comparison.

- anonymous

yes, that's what i would put

- anonymous

okay and what for part b

- 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

something along that line

- anonymous

omg thank you so much I wish I could give you a thousand medals

- anonymous

i'm sorry if it's wrong but that's what i would put if i got that problem

- anonymous

at this point I don't really care its the second to last test I have to take

- anonymous

lol ok well if you ever need help just tag me
