Answer:
see below for the tables
Step-by-step explanation:
The differential equation is separable, so the solution is ...
__
The values for yn are y+y'·h = y+2xyh. We take the "absolute error" to be the (signed) difference between the calculated yn and the actual value y(x).
Just convert the kilometers
If you do 81 x 9 which equals 729. If you want to check, you do 729 divided by 9 and you get 81.
Answer:
I think it's y-value is four more than corresponding x-value.
Let t and f be the number to two and four seat tables respectively.
t+f=22, solve for t
t=22-f, then we are told that capacity must be less than or equal to 72 people.
2t+4f≤72, using t found above in this equation we get:
2(22-f)+4f≤72 perform indicated multiplication on left side
44-2f+4f≤72 combine like terms on left side
44+2f≤72 subtract 44 from both sides
2f≤28 divide both sides by 2
f≤14 Since f=integer
f=14, and since t=22-f
t=8
So they should purchase 14 four seat tables and 8 two seat tables.
