only C) The diagonals bisect each other, and E) The diagonals are perpendicular are the two conditions that prove that a quadrilateral is a rectangle.

What is the quadrilateral?

A quadrilateral is a four-sided polygon, which means it has four straight edges and four angles. Quadrilaterals can come in many different shapes and sizes and can be classified based on their properties. Some common examples of quadrilaterals include squares, rectangles, parallelograms, rhombi, and trapezoids.

A quadrilateral is a rectangle if it satisfies the following conditions:

C) The diagonals bisect each other.

E) The diagonals are perpendicular.

A) Both pairs of opposite sides are congruent, is not a necessary condition for a quadrilateral to be a rectangle, as a rectangle can have different side lengths.

B) One pair of opposite sides is longer than the other pair of sides, is not a necessary condition for a quadrilateral to be a rectangle, as a rectangle can have equal side lengths.

D) The diagonals are congruent, is not a necessary condition for a quadrilateral to be a rectangle, as a rectangle can have diagonals of different lengths.

So, only C) The diagonals bisect each other, and E) The diagonals are perpendicular are the two conditions that prove that a quadrilateral is a rectangle.

The linear system l has one solution. This can be determined by examining the augmented matrix to find the row echelon form. The row echelon form is a matrix with zeroes below the leading entries and all the leading entries are in different columns.

By converting the augmented matrix into the row echelon form, we can identify the number of variables and the number of equations. Since there are three equations and three variables in the row echelon form, the linear system l has one solution. The row echelon form of the given augmented matrix is

[tex]$\begin{bmatrix}1&-3&2&3\\0&-5&-9&-10\\0&0&4&5\end{bmatrix}$[/tex]

By counting the number of equations and variables in the row echelon form, it can be seen that there is only one solution for the linear system l. This is because the number of equations is equal to the number of variables, indicating that there is a single solution.

Since lim a n/b n does not exist, it means that the ratio between a n and b n can be larger or smaller depending on the terms.

This implies that the rate of growth of a n and b n are not necessarily the same. If the series b n diverges, it means that the terms of b n increase without bound. Therefore, the terms of a n will also increase without bound, and sum a n will also diverge.

Formally, if lim a n/b n = ∞, then ∑ a n is divergent. We can prove this by contradiction. Suppose ∑ a n converges. Then by the comparison test, lim a n/b n must converge and be finite, which is a contradiction. Therefore, ∑ a n must diverge.

what are quadrilaterals?

A quadrilateral is a polygon with four sides, four vertices, and four angles.

It is formed by joining four non-collinear points. The sum of the interior angles of quadrilaterals is always equal to 360 degrees. The word quadrilateral is derived from the Latin words ‘Quadra’ which means four and ‘Latus’ means ‘sides’. Not all the four sides of a quadrilateral need to be equal in length. Hence, we can have different types of quadrilaterals based on sides and angles.

Five special quadrilaterals are shown below in the image, along with their definitions and pictures, and points for them to get proven.

Now,

Average velocity between the interval t = 10 min to t = 15 min is; 52.5 miles per hour

The expression showing  Di's average velocity, in miles per hour, t minutes after entering the interstate highway is;

v(t) = ¹/₂₀₀t³ + ³/₂₀t² - ³/₈t + 60

At t = 10 minutes, we have;

v(10) = ¹/₂₀₀(10³) + ³/₂₀(10²) - ³/₈(10) + 60

v(10) = 5 + 15 - 7.5 + 60

v(10) = 52.5 miles per hour

At t = 15 minutes, we have;

v(15) = ¹/₂₀₀(15³) + ³/₂₀(15²) - ³/₈(15) + 60

v(15) = 16.875 + 33.75 - 5.625 + 60

Answer: The given equations are not valid because there is no equal sign between the first and second equation. If you are trying to solve a system of equations it should be in the form of

3x + 5y = - 9

-6x - 5y = 18

You can solve for x and y by using different methods such as substitution, elimination or graphing.

In this case, you can add the first equation to the second equation:

3x + 5y = -9

-6x - 5y = 18

-3x = 27

x = -9

Now you can substitute this value of x into one of the equations to find the value of y.

3x + 5y = -9

3(-9) + 5y = -9

-27 + 5y = -9

5y = 18

y = 3.6

So, the solution is x = -9 and y = 3.6

It's important to check your solution by substituting the values of x and y in the original equations to make sure that the solution is consistent.

Step-by-step explanation:

The ordered pair that lies on the graph of the equation is (1, 2)

From the question, we have the following parameters that can be used in our computation:

y = 2x

The point in the ordered pair lies on the graph of the equation is the solution set

Take for instance, we set x = 2

So, we have

y = 2 * 1

Hence:

y = x + b.

When x = 3, y = 3, hence the intercept b is given as follows:

y = x.

The diagonals are perpendicular, meaning that the multiplication of their slopes is of -1, hence the slope of AC is of:

m = -1.

Hence:

Step-by-step explanation:

you mean the slope-intercept form of a line equation ?

y = mx + b

or what is the problem ?

if my assumption is correct, then m is the slope of the line.

and we got a point on the line.

so, we could start with the point-slope form and then transform.

the point-slope form is

y - y1 = m(x - x1)

again, m is the slope, (x1, y1) is a given point on the line.

so, we have

y - -8 = 6(x - 12)

y + 8 = 6x - 72

y = 6x - 80

that means b = -80

The Pythagorean Theorem holds true for both triangles, then the triangles are not only similar, but also congruent.

Triangle xyz has sides of length x, y, and z and triangle pqr has sides of length p, q, and r.

To determine if triangle xyz is similar to triangle pqr, we must calculate the ratios of corresponding sides. This is done using the formula:

Ratio of sides = (Side length x) / (Side length y)

We can calculate the ratios for each side of the triangles and compare them. If the ratios are equal for all sides, then the triangles are similar. For example, if the ratio of side x to side y in triangle xyz is equal to the ratio of side p to side q in triangle pqr, then the triangles are similar. If the ratios are not equal for all sides, then the triangles are not similar.

We can use the Pythagorean Theorem to determine if the triangles are not only similar, but also congruent. The Pythagorean Theorem states that a2 + b2 = c2, where c is the longest side and a and b are the other two sides. If the Pythagorean Theorem holds true for both triangles, then the triangles are not only similar, but also congruent.

The design of the experiment is Completely randomized over two factors (fertilizer and location).

Randomization is a statistical technique used in experimental design to ensure that all possible combinations of the factors being studied are represented in the study groups. It is used to eliminate bias and control for confounding variables that may affect the outcome of an experiment.

The researcher randomly assigned the tomato plants to be planted on either the sunny or the shady side of the hill. This creates two groups or two levels of the factor "location". She also randomly assigned the tomato plants to one of three groups based on the amount of fertilizer given, creating three groups or three levels of the factor "fertilizer".

The random assignment of plants to the different groups for both factors helps to ensure that any differences in the yield of tomatoes is due to the independent variables (fertilizer and location) being tested, and not due to other extraneous factors.

The space covered within an object's borders in three dimensions is referred to as its volume. It is refereed as the object's capability on occasion.

Volume, which is measured in cubic units, is the three dimensional volume occupied by matter or encircled by a surface. The cubic centimeter (m3), a derived unit, is the Standard unit of volume.

Substituting in the given information, we have:

V(m, θ) = sqrt(θ) * ln(m)

m(t) = t^2 + 3

θ(t) = e^t

Therefore:

dV/dm = (1/m) * sqrt(θ)

dm/dt = 2t

dV/dθ = (1/2sqrt(θ)) * ln(m)

dθ/dt = e^t

plugging in the values of m(t) = t^2 + 3 and θ(t) = e^t

dV/dt = (1/(t^2+3)) * sqrt(e^t) * 2t + (1/2sqrt(e^t)) * ln(t^2+3) * e^t
