perimeter:the continuous line forming the boundary of a closed geometric figure.

estimating:roughly calculate or judge the value, number, quantity, or extent of.

decimal number:decimal numeral system is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system is often referred to as decimal notation

You have asked to design a rectangle box with a square base and an open top. The volume of the box must be620 cm to the 3rd powe

hammer [34]

Answer:

$69.21

Step-by-step explanation:

Since the box has a square base the length and breadth of the box will be equal. Let it be $x$

Let h be the height of the box

V = Volume of the box = $620\ \text{cm}^3$

$x^2h=620\\\Rightarrow h=\dfrac{620}{x^2}$

Now surface area of the box with an open top is given

$s=x^2+4xh\\\Rightarrow s=x^2+4x\dfrac{620}{x^2}\\\Rightarrow s=x^2+\dfrac{2480}{x}$

Differentiating with respect to x we get

$\dfrac{ds}{dx}=2x-\dfrac{2480}{x^2}$

Equating with zero

$0=2x-\dfrac{2480}{x^2}\\\Rightarrow 2x^3-2480=0\\\Rightarrow x^3=\dfrac{2480}{2}\\\Rightarrow x=(1240)^{\dfrac{1}{3}}\\\Rightarrow x=10.74$

Double derivative of the function

$\dfrac{d^2s}{ds^2}=2+\dfrac{4960}{x^3}=2+\dfrac{4960}{1240}\\\Rightarrow \dfrac{d^2s}{ds^2}=6>0$

So, x at 10.74 is the minimum value of the function.

$h=\dfrac{620}{x^2}\\\Rightarrow h=\dfrac{620}{10.74^2}\\\Rightarrow h=5.37$

So, minimum length and breadth of the box is 10.74 cm while the height of the box is 5.37 cm.

The total area of the sides is $4xh=4\times 10.74\times 5.37=230.7\ \text{cm}^2$

The area of the base is $x^2=10.74^2=115.35\ \text{cm}^2$

Cost of the base is $0.40 per square cm

Cost of the side is $0.10 per square cm

Minimum cost would be

$230.7\times 0.1+0.4\times 115.34=\$69.21$

The minimum cost of the box is 69.21 dollars.

I need it by tmr<br> ill give brainliest thx

Zina [86]

Answer:

21. B. Graph Z

23. A. neither function nor relation

24. D. relation only

Step-by-step explanation:

21. Graph Z is the only graph which does not pass the vertical line test

23. The graph does not pass the vertical line test, AND it is not merely given x and y points like a relation. It is graphed as a squiggly line with no given x and y points, therefore you could not make a relation from it either.

24. There is an x value of -4 twice, meaning the set does not pass the vertical line test, HOWEVER, it is a given collection of x and y values, making it a relation.

I would appreciate brainliest, have an amazing day

What are the unknown measurements of the triangle? Round your answers to the nearest hundredth as needed.

maks197457 [2]

The unknown measurements of the triangle are C = 28°, c = 3.76 and b = 7.06.

Sine rule is used to show the relationship between sides of a triangle and the angles. It is given by:

$\frac{a}{sinA}= \frac{b}{sinB}=\frac{c}{sinC}$

Where a, b, c are the sides and the angles opposite the sides are A, B, C respectively.

A + B + C = 180° (angles in a triangle)
62 + 90 + C = 180
C = 28°

$\frac{a}{sinA}= \frac{b}{sinB}\\
\\
\frac{8}{sin(90)}=\frac{b}{sin(62) }\\
\\
b=7.06\\
\\
\\
\frac{a}{sinA}= \frac{c}{sinC}\\
\\
\frac{8}{sin(90)}=\frac{c}{sin(28) }\\
\\
c=3.76$

The unknown measurements of the triangle are C = 28°, c = 3.76 and b = 7.06.
