Answer:

Step-by-step explanation:

Given

square bottom area is 24\times 24\ in.^2

Suppose x in. is cut from each corner to make a open box with maximum volume

New base area is (24-x)\times (24-x) in.^2

Volume of box

V=(24-x)^2\times x

Differentiate V w.r.t x to get maximum volume

\frac{\mathrm{d} V}{\mathrm{d} x}=2\cdot (24-x)(-1)+1\cdot (24-x)^2

Put \frac{\mathrm{d} V}{\mathrm{d} x}=0

\left ( 24-x\right )\left [ -2x+24-x\right ]=0

\left ( 24-x\right )\left [ 24-3x\right ]=0

x=24,8

but x=24 is not possible therefore x=8 will yield maximum volume

V=(24-8)^2\cdot 8=2048\ in.^2

Ryan runs 3 miles in 28 minutes. at the same rate, how many miles would he run in 42 minutes?
Sphinxa [80]
If 3mile=28 min
x mile=42 min
cross multiply
x=3/28
therefore if 3/28=1 min
then x mile= 42 min
cross multiply
42 x 3/28 =21 x 3/14
                =3 x 3/1
                =9
The answer is 9 miles
