arindameducationusc
  • arindameducationusc
okay, I didn't notice that pic :D.. wait solving...
Destinyyyy
  • Destinyyyy
Okay
arindameducationusc
  • arindameducationusc
if you put x=25 in the first equation, you get y which is the answer
Destinyyyy
  • Destinyyyy
38,287
arindameducationusc
  • arindameducationusc
i guess you did that way.... that should be correct.
arindameducationusc
  • arindameducationusc
and in the second equation what did you put?
Destinyyyy
  • Destinyyyy
I got 38,614
Destinyyyy
  • Destinyyyy
And both of them were wrong.. I have a similar problem pulled up now
arindameducationusc
  • arindameducationusc
hmmm.... i will ask @phi
arindameducationusc
  • arindameducationusc
is the answer 32000, just asking?
phi
  • phi
the "fine print" says x is the number of years from 1980 if we want the number for year 2000, we want to use x= 2000-1980= 20 (not sure how we got 30!)
Destinyyyy
  • Destinyyyy
I think it was 32,202 but I cant see it any more.
arindameducationusc
  • arindameducationusc
@phi is here... He is awesome....... dont worry @Destinyyyy
Destinyyyy
  • Destinyyyy
So I ignore 1975??? O.o
phi
  • phi
the formula we use says "x is years from 1980". ok, then that is what we do.
texaschic101
  • texaschic101
for the first one you sub in 20 for x
Destinyyyy
  • Destinyyyy
34,202
phi
  • phi
ok
Destinyyyy
  • Destinyyyy
Is that the final answer?
phi
  • phi
it depends, do they want the exact number, or do they want you to round it to the nearest thousand?
Destinyyyy
  • Destinyyyy
It says round to the nearest thousand dollar as needed.
phi
  • phi
I know for part (a) you should round. (it is hard to read a graph very accurately)
Destinyyyy
  • Destinyyyy
Opps sorry read the wrong one. It says round to the nearest dollar as needed
phi
  • phi
then that is the answer (without the comma, probably)
Destinyyyy
  • Destinyyyy
Okay..What about C.?
Destinyyyy
  • Destinyyyy
Do the same thing?
phi
  • phi
x is still 20, but use a different equation
Destinyyyy
  • Destinyyyy
29,964
texaschic101
  • texaschic101
if you go by the graph, it looks like 32,000
Destinyyyy
  • Destinyyyy
Yes thats the answer for A.
phi
  • phi
I got a different number for part c
anonymous
  • anonymous

Destinyyyy
  • Destinyyyy
15,964
phi
  • phi
can you show your work?
Destinyyyy
  • Destinyyyy
-2(20)^2 +1020 (20) +14364 -2(400)+ 2400 +14,364 15964
phi
  • phi
1020*20 is not 2400
Destinyyyy
  • Destinyyyy
Yes my name is Destiny.
anonymous
  • anonymous
oh cool
Destinyyyy
  • Destinyyyy
Opps guess I typed plus instead of multiply
texaschic101
  • texaschic101
C = -2 (20^2) + 1020(20) + 14,364 C = -2(400) + 20,400 + 14,364 C = -800 + 20,400 + 14,364 C = -800 + 34,764 C = 33,964......I am getting this
Destinyyyy
  • Destinyyyy
Yes I just got that
Destinyyyy
  • Destinyyyy
So 33,964 is the final answer?
phi
  • phi
yes
Destinyyyy
  • Destinyyyy
Okay. Thank you!
texaschic101
  • texaschic101
if it does not have to be rounded...then yes
