Step-by-step explanation:

The dunking booth is the shape of a cube represented below (x+3). Therefore, the polynomial of volume of the dunking booth is

                                            (x +3) (x+3)².

Lets talk about the cube prism

- It has cube faces each two opposite faces are congruent

- It has three dimensions.

- Its volume = a³

In our problem the dunking booth is a cube prism with dimensions:  x + 3

Side = x +3

therefore,

V = a³ = ( x +3)³

          = (x)³ + 3× (x)²× 3 + 3× x × (3)² + (3)³

          = x³ + 9x² + 27x + 27

Regrouping ,

          = x³+ 27+ 9x² + 27x

Rewrite 27as 33.

x³+ 3³+9x²+ 27x

Since both terms are perfect cubes, factor using the sum of cubes formula,

a³+b³ = (a + b)(a²- ab+ b²) where a=x and b=3.

(x+3)(x− x⋅3 + 32)+ 9x²+ 27x

Simplify.

     (x+3)(x²− 3x + 9)+ 9x²+ 27x

⇒  (x+3)(x²− 3x + 9)+ 9x(x+3)

Now,

x+3 out of  (x+3)(x²− 3x + 9)+ 9x(x+3) .

⇒ (x+3)(x²− 3x + 9 + 9x)

Add −3x and 9x.

(x+3) (x²+ 6x+ 9)

Rewrite the polynomial.

   (x+3)(x²+ 2⋅x⋅3+ 3²)

Factor using the perfect square trinomial rule a²+2ab+b² = (a + b)² , where a = x and b = 3.

                  (x+3)(x+3)².

Therefore, the polynomial is   (x+3)(x+3)².

(b) True
(c) Yes

What is maximum and minimum?

The smallest value in the data set is the minimum. The largest value in the data set is the maximum.

(a) The circumference of the circle is xx, which means that

[tex]P_ 1= 2\pi r\\x = 2\pi r\\r = \frac{x}{2\pi }[/tex]

The area of the circle is,

[tex]A_c = \pi r^2\\A_c = \frac{x^2}{4\pi }[/tex]

The circumference of the square is L - x, which means

[tex]P_2 = 4a \\L-x=4a\\a = \frac{L-x}{4}[/tex]

The area of the square is,

[tex]A_s = a^2\\A_s=\frac{(L-x)^2}{16}[/tex]

The sum of the areas of the circle and the square is

[tex]A = A_c + A_s\\A = \frac{x^2}{4\pi } +\frac{(L-x)^2}{16} \\A = \frac{4x^2+(L-x)^2\pi \pi }{16\pi } \\A = \frac{4x^2+(L^2 -2Lx+x^2)\pi }{16\pi } \\A = \frac{(4+\pi )x^2-2Lx\pi +L^2\pi }{16\pi }[/tex]

The derivative of the function of the total area is

[tex]A = \frac{4+\pi }{8\pi }x-\frac{L}{8}[/tex]

We solve the equation A'(x) = 0

[tex]\frac{4+\pi }{8\pi }x-\frac{L}{8}=0\\ \frac{4+\pi }{\pi }x=L\\ x = \frac{L\pi }{4+\pi }[/tex]

So, [tex]x = \frac{L\pi }{4+\pi }[/tex] is a critical point A, and it is a global minimum of A since

[tex]A"(x) = \frac{4+\pi }{8\pi } > 0[/tex] for all x.

(b) The area of the circle for [tex]x = \frac{L\pi }{4+\pi }[/tex] is

[tex]A_c = \frac{(\frac{L\pi }{4+\pi } )^2}{4\pi } \\A_c = \frac{(\frac{L^2\pi ^2}{(4+\pi )^2} )}{4\pi } \\A_c= \frac{L^2\pi }{4(4+\pi )^2}[/tex]

The area of the square for [tex]x = \frac{L\pi }{4+\pi }[/tex]  is

[tex]A_s = \frac{(L-\frac{L\pi }{4+\pi } )^2}{16}[/tex]

The ratio of the area is,

[tex]\frac{A_s}{A_c} = \frac{(\frac{(L-\frac{L\pi }{4+\pi })^2 }{16} )}{(\frac{L^2\pi }{4(4+\pi )^2} )}[/tex]

[tex]= \frac{(L - \frac{L\pi }{4+\pi })^2 }{16}*\frac{4(4+\pi )^2}{L^2\pi } \\ = \frac{L^2-\frac{2L^2\pi }{4+\pi }+(\frac{L\pi }{4+\pi } )^2 }{4} *\frac{(4+\pi )^2}{L^2\pi } \\= \frac{(4+\pi)^2 }{4\pi }-\frac{4+\pi }{2}+\frac{\pi }{4}\\ = \frac{4}{\pi }[/tex]

The ratio of the length of wire in the square to the length of wire in the circle for [tex]x = \frac{L\pi }{4+\pi }[/tex]  is

[tex]\frac{L-x}{x} =\frac{L-\frac{L\pi }{4+\pi } }{\frac{L\pi }{4+\pi } } \\= \frac{\frac{4L}{4+\pi } }{\frac{L\pi }{4+\pi } } \\= \frac{4}{\pi }[/tex]

As we can see (1) = (2)

(c) To prove this, we solve the equation

[tex]\frac{A_s}{A_c} = \frac{L-x}{x} \\ \frac{\frac{(L-x)^2}{16} }{\frac{x^2}{4\pi } } = \frac{L-x}{x}\\ \frac{(L-x)^2}{4}*\frac{\pi }{x^2} = \frac{L-x}{x} \\ \frac{L-x}{4} *\frac{\pi }{x} =1\\L\pi -\pi x=4x\\L\pi = (4 + \pi )x\\x = \frac{L\pi }{4+x}[/tex]

As we can see, the equality is equal for only one value of xx, which was the same as the one we found in part (a).

J + k < 54 when  J = 5k + 6 so:

5k + 6  + k < 54

6k + 6 < 54

subtract 6 from both sides:

The polynomial equation with zeroes of -3, -1, 2 and y-intercept of -14 is x^3 +2x^2 -5x -20.

The zeros of a function f(x) are values of the variable x such that the values satisfy the equation f(x) = 0. The zeros of a function are also called the roots of a function.

if -3, -1, 2 are zeroes of y(x) with an intercept d then

y(x) = (x-a)(x-b)(x-c) + d

where a = -3, b = -1, c = 2, d = -14

Substituting we have

y(x) = (x+3)(x+1)(x-2) -14

let us expand the first two linear factors

(x+3)(x+1) =x^2 +3x + x + 3 which is x^2 + 4x + 3

multiply this result with (x-2), we have

(x-2)(x^2 + 4x +3)

x^3 + 4x^2 +3x -2x^2 -8x -6

simplifying it becomes x^3 +2x^2 -5x -6

y(x) =  x^3 +2x^2 -5x -6 -14

It is given to us that the test statistic is used for a two sample test of means where the population variances are unknown and unequal.

Pooled standard deviation estimates cannot be used when the two groups have unequal variances. Instead, we have to find out the standard error for each group separately.

The formula for this type of test statistic is given by -

[tex]t=\frac{x_{1} -x_{2} }{\sqrt{\frac{s_{1} ^{2} }{n_{1} } +\frac{s_{2} ^{2} }{n_{2} } } }[/tex] ------- (1)

Here, the variables can be defined as below -

[tex]s_{1} ^{2}[/tex], [tex]s_{2} ^{2}[/tex] = The variance of two samples

[tex]n_{1}[/tex], [tex]n_{2}[/tex] = The respective sizes of the two samples

[tex]t[/tex] = t-distribution test statistic

[tex]x_{1}[/tex], [tex]x_{2}[/tex] = Mean of the two samples

Elastic demand for a good is defined as when the price of a good rises by 10% while the quantity required falls by 20%.

When a product's price changes, consumer demand is said to be elastic. Consumers will purchase significantly more if the price drops just a little. They won't buy as much if prices increase somewhat instead opting to wait for them to level out.

If all other variables remain constant, the ratio of a product's percent change in demand to its percent change in price determines whether a product's demand is elastic or inelastic.

It is neither elastic nor inelastic for an item's price to alter in proportion to its change in demand. In other words, a product has elastic demand if demand fluctuates more than price does.

Hence, Elastic demand for a good is defined as when the price of a good rises by 10% while the quantity required falls by 20%.
