Step-by-step explanation:
yoooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo thats a test question
V= x*(10-2x)(8-2x)
for greatest volume, differentiate v w.r.t x and equate to 0,
dv/dx= (10-2x)(8-2x) + x(-2)(8-2x)+ x(10-2x)(-2)=0
you get x from solving the quadratic equation. volume will be max at that x
Answer:
60%
Step-by-step explanation:
Im almost positive this is right if not sorry have a blessed day :)
X(x-6) = 391
x2-6x-391 =0(x-23)(x+17)=0
since the number of seats should be positive,
x = 23
The number of rows is 23 - 6 = 17
( To check our work )
391 / 17 = 23
So, there are 17 rows of seats.
