The name for a quadrilateral with exactly two pairs of congruent consecutive sides is a kite.

A kite is a special type of quadrilateral that possesses two pairs of congruent consecutive sides. In other words, consecutive sides of a kite are equal in length.

A kite can be visualized as having two pairs of adjacent sides that are congruent, while the nonadjacent sides are not necessarily congruent. This creates an asymmetrical shape with two distinct diagonals.

To identify a kite, you can examine the lengths of its sides. If two pairs of consecutive sides have equal lengths, while the remaining sides do not, then the quadrilateral can be classified as a kite.

For example, consider the following side lengths for a quadrilateral: AB = BC = CD ≠ DA.

In this case, the sides AB and BC are congruent, as are the sides CD and DA. However, the nonadjacent sides, AB and CD, are not necessarily congruent.

A quadrilateral with exactly two sets of congruent following sides is called a kite. It is characterized by two pairs of adjacent sides that have equal lengths, while the nonadjacent sides may differ in length. Kites have unique properties and are commonly encountered in geometry and recreational mathematics.

The roots of 2x^2+4x+7 are -1 + i√5 and -1 - i√5.

A quadratic function has the generic form f(x)=ax²+bx+c. A parabola, a kind of two-dimensional curve, is the graph of a quadratic function. A polynomial function of degree two in one or more variables is known in algebra as a quadratic function, quadratic polynomial, polynomial of degree 2, or simply a quadratic. The phrase "quadratic" in mathematics refers to something that has to do with squares, the squaring operation, terms of the second degree, or equations or formulas that contain such terms. Latin's word for square is quadratus.

Function:

2x² + 4x + 7 = 0

ax² + bx + c = 0

x = \(\frac{-b +-\sqrt{}b^{2}- 4ac }{2a}\)

a = 2

b = 4

c = 7

Using quadratic function,

x = \(\frac{-4\sqrt{} 4^{2} -4(2)(7)}{2(2)}\)

x = \(\frac{-4+-\sqrt{-40} }{4}\)

So,

i = √-1

x = \(\frac{-4+-2i\sqrt{10} }{4}\)

Simplifying,

x = -1 +-√10/2

Roots are:

x = -1 + i√10/2

x = -1 - i√10/2

The roots of 2x^2+4x+7 are -1 + i√5 and -1 - i√5.

Answer:

Approx. 606.02 cubic inches more.

Step-by-step explanation:

\(Volume=\pi *(\frac{diameter}{2})^2*height\)

First, let's find the volume of the first cylinder (diameter=12, height=13).

\(V=\pi * (\frac{12}{2})^2 * 13\\V=\pi * (6)^2 * 13\\V=\pi * 36 * 13\\V=3.14*36*13\\V=113.04*13\\V=1469.52 in^3\)

Now let's find the volume of the second cylinder (d=10, h=11).

\(V_{2}=\pi * (\frac{10}{2})^2*11\\V_{2}=\pi * (5)^2*11\\V_{2}=\pi * 25 * 11\\V_{2}=3.14*25*11\\V_{2}=78.5*11\\V_{2}=863.5in^3\)

Lastly, we can subtract the volume of the second cylinder from the volume of the first cylinder.

This gets us a solution of 606.02 cubic inches.

Answer:

The length of the shadow of a 6ft tall man at 5pm would be approximately 7.2ft.

Step-by-step explanation:

We can use the ratio of the heights to the lengths of the shadows to find the length of the shadow of a 6ft tall man. Here are the steps:

Write the ratio of the height to the length of Cindy's shadow:

5/6

Set up a proportion with the ratio of the height to the length of the shadow for the 6ft tall man:

5/6 = 6/x

Cross-multiply to solve for x:

5x = 36

Divide both sides by 5:

x = 7.2

Therefore, the length of the shadow of a 6ft tall man at 5pm would be approximately 7.2ft.

a) To maximize its net savings, the company should use the new machine for 7 years.  b) The net savings during the first year of use of the machine are $405 (rounded off to the nearest dollar).  c) The net savings over the period determined in part a are $1,833.33 (rounded off to the nearest cent).

Step-by-step explanation: a) To determine for how many years should the company use the new machine to maximize its net savings, we need to find the value of x that maximizes the difference between the savings and the costs.To do this, we need to first calculate the net savings, N(x), which is given by:S'(x) - C'(x) = 175 - x² - (x² + 11x) = -2x² - 11x + 175To find the maximum value of N(x), we need to find the critical values, which are the values of x that make N'(x) = 0:N'(x) = -4x - 11 = 0 ⇒ x = -11/4The critical value x = -11/4 is not a valid solution because x represents the number of years of operation of the machine, which cannot be negative. (i.e., not use it at all).However, this answer does not make sense because the company would not introduce a new machine that it does not intend to use. Therefore, we need to examine the concavity of N(x) to see if there is a local maximum in the feasible interval.

We need to know the size of the pieces in order to calculate how many people can be fed equal-sized pieces of cake from a 16 by 18-inch cake.

Assume that each piece is a square with sides measuring "x" in length. Each piece's area would be x², and the cake's overall area would be 16 x 18 inches, or 288 square inches.

We must divide the entire area of the cake by the area of each piece to determine the maximum number of pieces that can be cut from the cake:

288 / x² = (16*18) / x² = 288 / x²

Choosing a "x" value that evenly splits into 16 and 18 is necessary if we want every piece to be the exact same size. Since 2 is the greatest possible value, we can divide the cake into 8 rows of 9 squares, yielding a total of 72 pieces.

As a result, a cake measuring 16 inches by 18 inches can be divided into 72 equal-sized pieces, each measuring 2 inches by 2 inches.

We can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

A two-dimensional figure, form, or planar lamina's area is a measurement of how much space it takes up in the plane.

To find out how many people can be served equal-sized pieces of cake from a cake that is 16 inches by 18 inches, we need to first determine the size of each piece of cake.

The total area of the cake is:

16 inches x 18 inches = 288 square inches

To divide the cake into equal-sized pieces, we need to determine the size of each piece. Let's assume we want each piece to be a square. To find the size of each square, we need to find the square root of the total area of the cake:

√(288 square inches) ≈ 16.97 inches

Since we want the pieces to be exactly the same size, we'll round down to the nearest inch, which gives us:

Each piece of cake will be approximately 16 inches by 16 inches.

To find out how many people can be served equal-sized pieces of cake, we need to divide the total area of the cake by the area of each piece:

288 square inches ÷ (16 inches x 16 inches) = 18

Therefore, we can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

80 = 2x

/2     /2

x = 40

Then we substitute x in the problems and solve

<BAD = x + 75 = 40 + 75 = 115

<CAE = 3x - 5 = 3(40) - 5 = 115

<BAC = 180 - 115 = 65

<DAE = 180 - 115 = 65
