The table that shows proportional relationship between x and y is table 1.

Proportional relationships are relationships between two variables where their ratios are equivalent. A proportional relationship is one in which two quantities vary directly with each other.

Therefore, proportional relationships can be represented mathematically as follows:

y ∝ x

y = kx

where

Hence, let's find the table that shows a proportional relationship as follows:

using the first table,

y = kx

0.5 = k

y = 0.5 × 2 = 1

Therefore, the constant of proportionality is 0.5 of the table 1 is 0.5. The table 1 is proportional.

The values of x, y, and z that correspond to the critical point of the function z = f(x,y) = 2x² + x + 4y + 3y², which are (-1/4,-2/3,-4/3).

To find the values of x, y, and z that correspond to the critical point of the function

z = f(x,y) = 2x² + 1x + 4y + 3y²,

we must first calculate the partial derivatives of the function with respect to x and y.

Using the chain rule of differentiation, we find:

dz/dx = 4x + 1 and dz/dy = 4 + 6y

Now we set these equations to zero and solve for x and y to get the critical points:

4x + 1 = 0 ⇒ x = -1/4 and 4 + 6y = 0 ⇒ y = -2/3

We can now substitute these values of x and y into the original function to find the corresponding value of z:

f(-1/4,-2/3) = 2(-1/4)² + 1(-1/4) + 4(-2/3) + 3(-2/3)² = -4/3

Therefore, the critical point of the function is (-1/4,-2/3,-4/3).

Thus, we have found the values of x, y, and z that correspond to the critical point of the function z = f(x,y) = 2x² + x + 4y + 3y², which are (-1/4,-2/3,-4/3).

Answer:

1800 bricks

Step-by-step explanation:

Given

Sidewalk = 100ft by 4ft

Brick = 8 inches by 4 inches

Required

Determine the minimum number of bricks

First, we need to determine the area of both;

\(Sidewalk = 100ft * 4ft\)

\(Sidewalk = 400ft^2\)

\(Brick = 8in * 4in\)

\(Brick = 32in^2\)

Number of bricks is calculated as follows;

\(Number = \frac{Sidewalk}{Brick}\)

\(Number = \frac{400ft^2}{32in^2}\)

Convert ft^2 to in^2

\(Number = \frac{400 * 144in^2}{32in^2}\)

\(Number = \frac{57600in^2}{32in^2}\)

The least amount of material required is 48 ft² (option A).

Let's assume the dimensions of the square base are x by x, and the height of the box is h. Since the volume of the box is given as 32 ft³, we have the equation:

Volume = x² * h = 32

To minimize the amount of material required, we need to minimize the surface area of the box. The surface area consists of the area of the base and the lateral area (four sides).

The area of the base is x², and the lateral area is given by 4xh since there are four sides with dimensions x by h.

The total surface area is then given by:

Surface Area = x² + 4xh

To minimize this surface area, we can use the volume equation to express h in terms of x:

h = 32 / (x²)

Substituting this back into the surface area equation:

Surface Area = x² + 4x(32 / x²)

= x² + 128 / x

To find the minimum surface area, we can take the derivative of the surface area equation with respect to x and set it equal to zero:

d(Surface Area)/dx = 2x - 128 / x² = 0

Multiplying through by x²:

2x³ - 128 = 0

Simplifying:

2x³ = 128

x³ = 64

x = ∛64

x = 4

Now that we have the value of x, we can substitute it back into the volume equation to find the height:

h = 32 / (x²)

h = 32 / (4²)

h = 32 / 16

h = 2

So, the dimensions of the box that minimize the amount of material required are x = 4 and h = 2.

To calculate the surface area, we can substitute these values into the surface area equation:

Surface Area = (4)² + 4(4)(2)

= 16 + 32

= 48 ft²

Therefore, the least amount of material required is 48 ft² (option A).

The new volume of the cylinder is $100$ cubic feet.

Let the original radius and height of the cylinder be $r$ and $h$, respectively. Therefore, the original volume of the cylinder is given by $\pi r^2 h = 100$. After the radius decreases by $10%$ and the height increases by $10%$, the new radius and height become $0.9r$ and $1.1h$, respectively. The new volume of the cylinder can be calculated as $\pi (0.9r)^2 (1.1h) = 0.891\pi r^2 h$. Since $0.891\pi r^2 h = 100$, the new volume of the cylinder is $100$ cubic feet.

The term that refers to the fact that the distance between two or more points is equal is "equidistant".

In geometry, the concept of equidistance is important when dealing with circles, which are sets of points that are equidistant from a single point called the center. This property is what allows circles to be defined in terms of their radius, which is the distance between the center and any point on the circle.

Equidistance is also important in other areas of mathematics and science. For example, in physics, equidistant points can be used to define a plane or surface that is perpendicular to a given line or axis. This is useful in many applications, such as designing electronic circuit boards or constructing buildings.

The concept of equidistance is not limited to mathematics and science, however. It can also be applied in everyday life. For instance, if you are planning a road trip and want to visit several destinations that are equidistant from your starting point, you can use this information to help plan your route and estimate your travel time.

Given that the proportion of yellow paper in the collection is known, it can be estimated that out of a total of 800 draws, the yellow paper will be drawn around 180 times.

The probability of getting yellow is 36/160 or 0.225.

To see the need for yellow stickers in 800 draws, we multiply the result by the number of draws: 0.225 x 800 = 180.

If a paper clip is drawn 80 times in total, we need to draw the blue paper. It will be drawn 21 times.

The probability of drawing a blue card is 42/160 or 0.2625.
