How much greater is the median number of pairs of shoes in the inventory at the Golf pro Shop than the median number of pairs of shoes in the inventory at the Tennis Pro Shop?

The volume of the coffee in the can if the can has a radius of 4 inches and height of 9 inches is 452.16 inches³.

The can must be in the shape of a cylinder.

The formula to find the volume of the cylinder is,

Volume of cylinder = π r² h

Here r is the radius of the base of the cylinder and h is the height of the cylinder.

Given, Radius, r = 4 inches and Height, h = 9 inches

Volume of the coffee = π (4)² (9)

                                    = 144 π

                                    = 144 × 3.14

                                    = 452.16 inches³

Thus, the volume of the coffee in the can is 452.16 inches³.

In addition to ...

 degenerate ellipse

 point

it is also a degenerate circle (special case of ellipse).

___

The vertex of a double-napped cone is a point. So, the intersection of only the vertex with a plane is a point, not a degenerate parabola (a line) or degenerate hyperbola (pair of crossing lines).

Essentially, the plane must intersect at an angle greater than the angle of the edge of the cone with the axis of the cone. If the plane is not at the vertex, such an intersection angle will result in a circle or ellipse. As the plane gets closer to the vertex, the ellipse gets smaller, degenerating to a single point.

Answer:

The answer is:

        Degenerate ellipse.

         Point.

Step-by-step explanation:

We know that when a plane intersects a double-napped cone only at the cone's vertex then the cross-section that is obtained is the point.

Also we know that a point is also considered as a circle with radius 0.

and a circle is also a kind of a ellipse when the length of both the transverse and conjugate axis are equal.

Hence, the term that best describe the degenerate conic section that is formed is:

No, Danielle needs to remove 1 rectangle from the ramp and 1 rectangle from the block.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.

The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area. The space inside the perimeter or limit of a closed shape is referred to as the "area".

Danielle calculated the area by adding the areas of 2 triangular faces and 3 rectangular faces from the ramp and 6 rectangular faces from the block.

Danielle calculated some extra Areas.

Answer:

8 times

Step-by-step explanation:

I found the volume of the sphere. Then increased it how many times he blew. That was the ratio.

Also, Khan :)

The ratio of the current volume of the balloon to the original volume of the balloon is 8.

The volume of a sphere is given by (4\3)πr³ where r is the radius of the sphere.

The initial volume of the balloon = [tex]\frac{4}{3} \pi 2^{3}[/tex]

The initial volume of the balloon =[tex]\frac{32}{3} \pi[/tex]

Radius of the balloon after first breath = 2+1 =3cm

The Radius of the balloon after the second breath = 2+2=4cm

So, the new volume of the balloon = [tex]\frac{4}{3} \pi 4^{3}[/tex]

The new volume of the balloon = [tex]\frac{256}{3} \pi[/tex]

The ratio of new volume to the initial volume = [tex]\frac{\frac{256}{3 } \pi }{\frac{32}{3}\pi }[/tex]

The ratio of new volume to the initial volume =8

Hence, the ratio of the current volume of the balloon to the original volume of the balloon is 8.

There are three x-intercepts: x=-1; x=2 and x=-2 (therefore, options A and D are incorrect).

Since before brackets is sign "-", you should state that graph starts down on the left (you can check this substituting smaller negative number than -2 into function expression. For example, if x=-10, then f(-10)=-(-10+2)(-10+1)(-10-2)=-(-8)(-9)(-12)>0) and goes up on the right (you can check this substituting greater positive number than 2 into function expression. For example, if x=10, then f(-10)=-(10+2)(10+1)(10-2)=-(12)(11)(8)<0).

Answer: The possible source of error in this activity is " the accuracy of making and recording measurements"

The height of each and every student in the class has to be taken very accurately. Even if there was a single error in either making the calculation or even recording it, the average height will take a hit and will result in the entire exercise being a failure.

Hence, it’s very important to accurately measure the height and record and even have a second person do the same activity so that the numbers recorded are accurate.

1. Brett was right because her baseball reached a maximum height of 103.52 feet.

2. A table that justifies Brett's claim is shown below.

In Mathematics and Geometry, the maximum value of any function is a point on the graph where the function reaches its highest point. Additionally, the maximum value of Brett's quadratic function can be determined by finding the axis of symmetry;

Axis of symmetry, x = -b/2a

[tex]h(t) = -16t^2 + 79t + 6[/tex]

where:

a = -16,  b = 79, and c = 6.

By substituting the values of a and b into the formula, we have;

Axis of symmetry, x = -79/2(-16)

Axis of symmetry, x = 79/32 = 2.46875.

Now, we can determine the maximum value (vertex) as follows;

[tex]h(t) = -16t^2 + 79t + 6\\\\h(2.46875) = -16(2.46875)^2 + 79(2.46875) + 6[/tex]

h(2.46875) = 103.52 feet.

Based on the graph, we can logically deduce that the maximum height attained by Andre's baseball was below 80 feet. Hence, Brett was right.

Lastly, we would complete the table as follows;

t            Brett         Andre

0             6                 6

1              69              58

2             100             78

3              99              67

4              66               6

5               0                

In conlusion, we can logically deduce that Brett was right because her baseball reach a maximum height of 103.52 feet, which was greater than Andre's.

Answer:

Step-by-step explanation:

Given is a rational algebraic expression in x as

[tex]\frac{5x+2}{x^4-4x^2}[/tex]

First let us factorize the denominator.

[tex]x^2(x^2-4)\\=x^2(x+2)(x-2)[/tex]

Let the given term be

[tex]\frac{A}{x} +\frac{B}{x^2} +\frac{C}{x-2} +\frac{c}{x+2} \\\\=\frac{Ax(x^2-4)+B(x^2-4)+cx^2(x+2)+Dx^2(x-2)}{x^4-4x^2}[/tex]

Equate the numerator to get

[tex]Ax(x^2-4)+B(x^2-4)+cx^2(x+2)+Dx^2(x-2)[/tex]=[tex]5x+2[/tex]

Substitute x =-2

[tex]4D (-4) = -8\\D=\frac{1}{2}[/tex]

Now substitute x =2

We get

[tex]16C=12\\C=\frac{3}{4}[/tex]

Put x=0

[tex]-4B=2\\B=\frac{-1}{2}[/tex]

Next equate X cube terms to 0 on right side

[tex]A+C+D=0\\A=\frac{-5}{4}[/tex]

Hence partial fraction is

[tex]\frac{-1}{2x^2} -\frac{5}{4x} +\frac{1}{2(x+2)} +\frac{3}{4(x-2)}[/tex]

To decompose the rational expression startfraction 5x + 2 over x4 - 4x2 endfraction into partial fractions, we need to factor the denominator. The partial fraction decomposition of the given rational expression is startfraction A over x + B over x2 + C over (x - 2)2, where A, B, and C are the determined coefficients.

To decompose the rational expression startfraction 5x + 2 over x4 - 4x2 endfraction into partial fractions, we need to factor the denominator. The denominator can be factored as x2(x2 - 4) which gives us two distinct linear factors x and x + 2, and a repeated linear factor x - 2. Therefore, we can express the rational expression as follows: startfraction A over x + B over x2 + C over (x - 2)2.

To find the values of A, B, and C, we can use the method of equating coefficients. By multiplying both sides of the equation by the common denominator, we can eliminate the fractions and solve for the unknowns. Finally, we substitute the values of A, B, and C back into the partial fraction decomposition expression.

Therefore, the partial fraction decomposition of the given rational expression is startfraction A over x + B over x2 + C over (x - 2)2, where A, B, and C are the determined coefficients.

Answer:

At 10 PM both candles will be same height.

Step-by-step explanation:

Let h represent the number of hours.

We have  twelve inch candle and an 18 inch candle are lit at 6pm and the 12-in. candle burns 0.5 inches every hour. The 18 inch candle burns 2 inch every hour.

Height 18 inch candle after h hours, = 18 - 2h

Height 12 inch candle after h hours, = 12 - 0.5h

At same height we have

                18 - 2h = 12 - 0.5h

                   1.5 h = 18 - 12

                         h = 4 hours.

Time = 6 PM + 4 hours = 10 PM

At 10 PM both candles will be same height.

Answer:

At 10 PM, both the candles will be of same height.

Step-by-step explanation:

Two candles are lit at 6 PM.

The length of candles is 12 inch and 18 inch.

The rate of burning of 12 inch candle is 0.5 inch per hour.

The rate of burning of 18 inch candle is 2 inch per hour.

Let [tex]h[/tex] represents the number of hours of burning.

In [tex]h[/tex] hours, the remaining length of the 12 inch candle will be,

[tex]l_1=12-0.5\times h[/tex]

In [tex]h[/tex] hours, the remaining length of the 18 inch candle will be,

[tex]l_2=18-2\times h[/tex]

Now, it is required to find the time at which the length of both the candles will be same.

So, the time [tex]h[/tex] in hours will be,

[tex]l_1=l_2\\12-0.5h=18-2h\\1.5h=6\\h=4\rm hour[/tex]

So, after 4 hours, both the candles will be of same length.

Therefore, the time will be [tex]6+4=10[/tex] PM. At 10 PM, both the candles will be of same height.
