Determine the dimensions of a rectangular solid (with a square base) with maximum volume if its surface area is 529 square meter
Zielflug [23.3K]

Answer:

x=23/\sqrt{6},

y= \frac{23}{6\sqrt{6}}

Step-by-step explanation:

From the question we are told that

Surface area is 529 square meters

Generally the dimensions of the cuboid

v=x^y

D=4xy+2x^2 =529

V=x^29(\frac{529-6x^2}{4x})

V' =529-6x^2/4

v'=0

Therefore

529=6x^2

x=\sqrt{\frac{529}{6} }

x=23/\sqrt{6}

Mathematically

v''=\frac{12x}{4}

v''=-3\frac{23}{\sqrt{6} }

y= \frac{529-2*(\frac{529}{6} }{4*\frac{23}{\sqrt{6} } }

y= \frac{23}{6\sqrt{6}}

Therefore

x=23/\sqrt{6}

and

y= \frac{23}{6\sqrt{6}}

Thepotemich [5.8K]

Anja’s phrase should have ended with “less than –15”, not “at least –15”.

Given statement:

Anja represents the inequality (4-g)/8 <-15

With the phrase “the quotient of the difference of 4 and a number and 8 is at least –15.”

Let the number be g.

“the quotient of the difference of 4 and a number and 8" translated to (4-g/8)

"at least" means : <

“the quotient of the difference of 4 and a number and 8 is at least –15.” translated to (4-g)/8 <-15

Therefore, Anja’s phrase should have ended with “less than –15”, not “at least –15”.
