A trapezoid is a quadrilateral with exactly one pair of?

The best describe Maria's solution to the equation is Maria incorrectly applied the associative property in going from the line(1) to line(2).

What is associative property?

Rearranging the parenthesis in an expression will not change the outcome since some binary operations in mathematics have the associative feature. Associativity is a legitimate rule of replacement for expressions in logical proofs in propositional logic.

Here, we have

Given:  The equation -2(3x - 5) = 40

-2(3x - 5) = 40

-6x + 10 = 40

-6x = 40 - 10

-6x = 30

x = -5

The solution to the equation is -5 instead of -25/3.

Hence, the best describe Maria's solution to the equation is Maria incorrectly applied the associative property in going from the line(1) to line(2).

A 15 degree angle can be created by using a compass or a straightedge.

1) Using a compass: Set the compass to the length of the angle's ray, and draw an arc that intersects the angle's vertex. Repeat the process with a second arc, and the point of intersection between the two arcs is the endpoint of the angle's ray.

2) Using a straightedge and 30-60-90 triangles: You can use a straightedge to bisect a 30-degree angle, then use the bisector to construct a 15-degree angle.

These are just a few ways to construct a 15-degree angle without a protractor, and there might be other methods as well.

No, the derivative of a logarithmic function is a power function.The derivative of a logarithmic function y = log_a(x) is given by dy/dx = 1/x log_a(e).

The derivative of a logarithmic function of the form y = log_a(x) is given by

dy/dx = 1/x log_a(e)

This is a power function, not a logarithmic function.

The derivative of a logarithmic function y = log_a(x) is given by dy/dx = 1/x log_a(e). This is not a logarithmic function, but rather a power function. This form of the derivative of a logarithmic function is derived from the definition of the logarithm, which is the inverse of the exponential function. The derivative of an exponential function is a power function, and the derivative of a power function is a logarithmic function, so the derivative of a logarithmic function is a power function. The derivative of a logarithmic function is important because it allows us to study the rate of change of a logarithmic function. This rate of change can be used to determine the behavior of a logarithmic function, such as its maximum and minimum points, as well as its concavity. Knowing the derivative of a logarithmic function is essential in understanding the behavior of logarithmic functions.

The polynomial 2x^3 - 3x^2 x 5 is known as a cubic polynomial.

A cubic polynomial is a polynomial of degree 3, or a polynomial with the highest power of x being 3. This means that the formula for a cubic polynomial can be written as ax^3 + bx^2 + cx + d, where a, b, c, and d are all constants.

In the example of 2x^3 - 3x^2 x 5, the coefficients are 2, -3, 0, and 5 respectively. To calculate the value of the cubic polynomial, one must substitute a value of x into the equation. For example, if x = 2, then the equation would be 2(2^3) - 3(2^2) x 5, which simplifies to 32 - 24 x 5, or 32 - 120, which equals -88.

Therefore, when x = 2, the polynomial 2x^3 - 3x^2 x 5 equals -88. This can be further verified by graphing the polynomial and observing the point (2, -88).

0 is the value of log 1 to base 7.

The inverse of an exponential function is named a logarithm. That means the logarithm of a number y to the base b is the exponent to which b must be raised, to produce y. For example, since 100 = 10², the logarithm base 10 of 100 is 2, or log₁₀ (100) = 2. The logarithm of x to base a is denoted as logₐ (x), or without parentheses, logₐ x, or even without the explicit base, log x.

As we know,

aˣ = N ⇔ [tex]log_{a}N[/tex] = x

Let log₇1 = x

⇒7ˣ = 1

⇒7⁰ = 1

Equating powers on both sides, we get
