The function H(t) = −16t2 + 96t + 80 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) = 31 + 32.2t, 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 2 through 5 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points) Part B: Explain what the solution from Part A means in the context of the problem. (4 points) Can you pplease help mE??? @triciaal

Hi

@triciaal can you help?
triciaal
  • triciaal
going through the closed questions just did this think yesterday
triciaal
  • triciaal
new part A do the table
triciaal
  • triciaal
|dw:1437583979413:dw|
triciaal
  • triciaal
fill out the table completely look at the values of H(t) and g(t) and see where they are approximately equal then look at the "t" column to see between what 2 integers
anonymous
  • anonymous
I have no clue
triciaal
  • triciaal
what do you mean by that? did you actually read my response?

i dont know how you did that, the graph and stuff. i dont know how that correlates to the question @triciaal

THANKYOU
anonymous
  • anonymous
np
anonymous
  • anonymous
she took the 2 expressions from the begging and substituted numbers 2 through 5 for t so u just solve and make the table
anonymous
  • anonymous
begining
anonymous
  • anonymous
okay i see that
anonymous
  • anonymous
so now u just solve the equations and write the numbers in for the table
anonymous
  • anonymous
for example for the first equation -16t^2+96t+80 ill substitute in 2
anonymous
  • anonymous
-16(2)^2+96*2+80 -16*4+96*2+80 -64+192+80 208
anonymous
  • anonymous
ok ill try, what number do i plug in for t?
anonymous
  • anonymous
well i did 2 so u do 3 for t
anonymous
  • anonymous
ill check it
anonymous
  • anonymous
tell me when ur done
anonymous
  • anonymous
-16(3)^2+96*3+80= 224
anonymous
  • anonymous
yep so now do 4 for t then 5 for t after that
anonymous
  • anonymous
ok
anonymous
  • anonymous
what did u get
anonymous
  • anonymous
-16(4)^2+96*4+80=208 -16(5)^2+96*5+80=160
anonymous
  • anonymous
yep so now ur halfway done with part A
anonymous
  • anonymous
yyay
anonymous
  • anonymous
31+32.2*t is ur new equation so just do the same thing again t for 2 then 3 then 4 then 5
anonymous
  • anonymous
-16(2)^2+96*2+80=208 -16(3)^2+96*3+80= 224 -16(4)^2+96*4+80=208 -16(5)^2+96*5+80=160
anonymous
  • anonymous
no now use the equation 31+32.2t and plug in 2 then 3 then 4 then 5 for t
anonymous
  • anonymous
ooh okay sorry
anonymous
  • anonymous
sokay
anonymous
  • anonymous
31+32.2(2)=95.4 31+32.2(3)=127.6 31+32.2(4)=159.8 31+32.2(5)=192
anonymous
  • anonymous
good now plug those into the table
anonymous
  • anonymous
how do i do that?
anonymous
  • anonymous
it should look like this |dw:1437587989265:dw|
anonymous
  • anonymous
Yea, is that what i put for part A?
anonymous
  • anonymous
yep
anonymous
  • anonymous
well u also have to say when are they equal
anonymous
  • anonymous
ok awesome, im gonna write that down, then can we do part B?
anonymous
  • anonymous
when do u think they are equal
anonymous
  • anonymous
between which 2 t numbers
anonymous
  • anonymous
erm they arent?
anonymous
  • anonymous
not at that exact second (remeber t stands for seconds) but between which two numbers would it be. for example lets say u had 2 for one and 3 for the other at 1 sec then 3 for one of them and 2 for the other that means inbetween the seconds they were equal
anonymous
  • anonymous
so between which seconds do u think they were equal
anonymous
  • anonymous
H(t) 4 and G(t)5
anonymous
  • anonymous
u just say between 4 and 5 seconds
anonymous
  • anonymous
Awesome thanks
anonymous
  • anonymous
Can you help with B?
anonymous
  • anonymous
now lets do part b remmeber u have to explain how u got between 4 and 5 secs
anonymous
  • anonymous
ok i got it down, now can you help with B?
anonymous
  • anonymous
so what do u think it means that they where the same between 4 and 5 Hint:talk about what its about read the question to find what was happening
anonymous
  • anonymous
It means the in feet, of projectile after 4 seconds, the same as A second object moves in the air along a path at 5 seconds
anonymous
  • anonymous
yep good job!
anonymous
  • anonymous
@lealealea222 before u close it can u do me a favor
anonymous
  • anonymous
hello @lealealea222
anonymous
  • anonymous
yea sure
anonymous
  • anonymous
can u medal @triciaal instead of me
anonymous
  • anonymous
um yea sure
anonymous
  • anonymous
oh yea i see, she medaled you
anonymous
  • anonymous
its just that i worked off of what he said so he helped first so he deserves it
anonymous
  • anonymous
yea thats true, thankyou for helping
