On a coordinate plane, 2 trapezoids are shown. The first trapezoid has points A (negative 1, 0), B (0, 2), C (3, 2), and D (4, 0

). The second trapezoid has points A prime (negative 1, 0), B prime (0, negative 2), C prime (3, negative 2), and D prime (4, 0).

Arrange the circles (represented by their equations in general form) in ascending order of their radius lengths. Tiles x2 + y2 −
sashaice [31]
When doing this, we would have to first straight them all out, and as we see above, they are just all over the place, and then, we would have to set them up as a sequence.

\left[\begin{array}{ccc}5x2 + 5y2 - 20x + 30y + 40 = 0\end{array}\right] would be our first step in this problem mainly because it contains the most terms in this aspect.

Then we would then x2 + y2 - 2x + 2y -1 = 0, then, 2x2 + 2y2 - 28x - 32y - 8 = 0.

These would only be our first 3 part of the sequence in this aspect.

The others would then be the following:

\boxed{x2 + y2 + 12x - 2y - 9 = 0 } \ then \ , \boxed{x2 + y2 - 4x + 4y - 10 = 0} \\ \\ then \ \boxed{x2 + y2 - 8x - 6y -20 = 0}

Thus, as we would have one more afterward, our last part of the sequence would then be the following.

\boxed{\boxed{4x2 + 4y2 + 16x + 24y - 40 = 0}}

I hope this was found helpful!

Answer:

It represents a mosquito that flew very fast after feeding relative to all other mosquitoes.

Step-by-step explanation:

The point is unusual because the velocity of the mosquito is substantially greater than all other velocities and is probably an outlier.

Consider the statement: The cube of any rational number is a rational number. a. Write the statement formally using a quantifier
3241004551 [841]

Answer:

(a)∀ r∈ℝ, r∈ℚ, r³∈ℚ

(b)True

Step-by-step explanation:

Definition

1. A real number is said to be rational if and only if there exists two integers a and b such that \frac{a}{b}=r where b≠0.

2. If the product of three numbers is zero, then at least one of the numbers must be zero.

Given Statement

The cube of any rational number is a rational number.

This can be rewritten as:

For all real numbers, if the number is rational then its cube is rational.

If we introduce our variable r,

For all real number r, if r is rational, then r³ is rational.

∀ r∈ℝ, r∈ℚ, r³∈ℚ

(b)The Statement is True.

To prove: The cube of any rational number is rational.

Proof:

We assume that r is a rational number and prove that its cube is a rational number.

By definition, there exists integers a and b such that:

r=\frac{a}{b} where b≠0.

r^3=(\frac{a}{b})^3

r^3=\frac{a^3}{b^3}

Since the cube of an integer is also an integer, a³ and b³ are also integers.

Since b is non-zero, then the zero product property tells us that its cube is also non-zero.

Conclusion:

r^3=\frac{a^3}{b^3} is rational since a³ and b³ are integers and b is non-zero.
