Answer:

The dimension of box=[tex]2ft\times 2ft\times 1ft[/tex]

Step-by-step explanation:

We are given that

Volume of box=4 cubic feet

Let x be the side of square base and h be the height of box

Volume of box=[tex]lbh=x^2h[/tex]

[tex]4=x^2h[/tex]

[tex]h=\frac{4}{x^2}[/tex]

Now, surface area of box,A=[tex]x^2+4xh[/tex]

[tex]A=x^2+4x(\frac{4}{x^2})=x^2+\frac{16}{x}[/tex]

[tex]\frac{dA}{dx}=2x-\frac{16}{x^2}[/tex]

[tex]\frac{dA}{dx}=0[/tex]

[tex]2x-\frac{16}{x^2}=0[/tex]

[tex]2x=\frac{16}{x^2}[/tex]

[tex]x^3=8[/tex]

[tex]x=2[/tex]

[tex]\frac{d^2A}{dx^2}=2+\frac{32}{x^3}[/tex]

Substitute x=2

[tex]\frac{d^2A}{dx^2}=2+\frac{32}{2^3}=2+4=6>0[/tex]

Hence, the area of box is minimum at x=2

Therefore, side of square base,x=2 ft

Height of box,h=[tex]\frac{4}{2^2}=1 ft[/tex]

Hence, the dimension of box=[tex]2ft\times 2ft\times 1ft[/tex]

8. Who was right, Emily or Zach? Are the products the same with the three different methods of multiplication? (1 point)

Emily was right, the products are the same with all three different methods of multiplication.

9. Which of these three methods is your preferred method for multiplying polynomials? Why? (1 point)

I prefer the table method because it is easier to understand what is going on, know where and what to do, and it is nicely and neatly laid out in front of me.

Answer:

A y=2x + 3

Step-by-step explanation:

Answer:

The answer is A. (y = 2x + 3)

Step-by-step explanation:

Since its talking about $3 plus $2 per dog it would make sense to pick

y = 2x + 3 because 2x represents the number of dogs and how it costs $2 per dog while the 3 represents how it also cost $3 plus the $2.

Answer:

1.563

Step-by-step explanation:

Given :

Probability of head, p = 0.64

Number of flips it would take for tail to appear first :

Treatting the question as a geometric function :

Using the relation :

1 / p

Expected number of flips until first tail :

1 / P = 1/ 0.64 = 1.5625

E(x) = expected number of flips until first tail = 1.563

Step-by-step explanation:

I can only answer part 2 of your question, "If we multiply two positive numbers, is the result positive or negative?". if you multiply 2 positive numbers your answer would be positive.

If we multiply two positive numbers, then the result is also positive.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that If a car is traveling east when it passes the camera, then;

the position be positive 60 seconds after it passes the camera.

Therefore, If we multiply two positive numbers, then the result is also positive.

Answer:

4/8

Step-by-step explanation:

The value of x is 5.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

ΔKLM ≈ ΔKQP

This means,

KL/KQ = KM/KP

(3x - 1) / 7 = 8/4

Cross multiply.

3x - 1 = 2 x 7

3x - 1 = 14

3x = 14 + 1

Divide both sides with 3.

3x = 15

x = 5

Thus,

x is 5.
