i dont know . i'm sorry.......
<span>2x+y=400
A=xy area of farmland
y=400-2x
A=400x-2x^2
A'(x)= 400 -4x derivative of area with respect to x
0=400-4x find out where f ' equals 0
4x=400
x=100
A'(x)= 400 -4x
A''(x)= -4 check 2nd derivative. if negative then relative max at x=100
2x+y=400
y=200
dimensions 100x200
hope it helped</span>
Put into graphing calculator and get B.-5,1,3
We have the following vectors:
u = <-6, -2>
v = <-2, 3>
Let's multiply each vector by its corresponding scale:
-3u = <18, 6>
2v = <-4, 6>
Now we add the new vectors:
-3u + 2v = <18, 6> + <- 4, 6>
-3u + 2v = <(18-4), (6 + 6)>
-3u + 2v = <14, 12>
Answer:
-3u + 2v = <14, 12>
