The distance between two points (2, 3) and (5, 7) is 5 units.

Therefore the answer is 5.

To find the distance between the points (2, 3) and (5, 7), we can use the distance formula:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

where (x₁, y₁) = (2, 3) and (x₂, y₂) = (5, 7)

Substituting the coordinates of the two points into the formula:

d = √((5 - 2)² + (7 - 3)²)

d = √((3)² + (4)²)

d = √(9 + 16)

d = √(25)

d = 5

So the distance between the points (2, 3) as well as (5, 7) will be  5 units by solving the above expression.

The ant population increases by factor of 5 every week. After 3 weeks, there will be 800 ants in the farm.

The problem can be solved by considering the ant population growth as a geometric sequence.

In a geometric sequence, a term is obtained by multiplying the previous term by a constant, which is called a common ratio. We can consider this common ratio as a growth factor.

In this case, the common ratio = 5

week 1 = 32 ants

week 2 = 32 x 5 ants = 160 ants

week 3 = 160 x 5 ants = 800 ants

We can also find the number of ants using the geometric sequence formula for the nth term:

a(n) = a . rⁿ⁻¹

Where:

a = first term = 32

r = common ratio = 5

Hence,

a(3) = 32 x 5² = 800 ants

There are 364 solutions to the given inequality: x1 + x2 + x3 <= 11.

To get the solution of the inequality x1 + x2 + x3 <= 11, we first need to include an additional variable in the inequation to write in as an equation.

Therefore, let the additional variable be x4.

Thus, equation is x1 + x2 + x3 + x4 = 11

The number of solutions of an equation can be calculated by the formula,

[tex]( \left \ {{n+ r - 1} \atop {n}} \right.)[/tex], where n is the constant value of the equation and r is the number of variables in the equation.

In this case, n = 11 and r = 4

Bob spends 9 minutes running for every 36 minutes that he spends practicing dribbling.

What is ratio ?

A ratio is a mathematical comparison of two or more values or quantities. It is a way of expressing the relationship between different amounts or measurements.

The ratio of running to dribbling is 5 minutes of running to 20 minutes of dribbling. We can use this ratio to find out how many minutes Bob spends running if he spends 36 minutes practicing dribbling.

First, we can set up a proportion with the known ratio and the unknown value ,

5/20 = x/36

To find x we can cross-multiply to get ,

20x = 180

then divide both sides by 20 ,

x = 9

So, Bob spends 9 minutes running for every 36 minutes that he spends practicing dribbling.

The linear equation perpendicular to the line y = 1/2x - 4 is:

y = -2x + 25

A general linear equation can be written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

And two lines are perpendicular if the product between the slopes is -1, then if we want to find a line perpendicular to:

y = 1/2x - 4

Then the slope m must be sch that:

m*(1/2) = -1

m = -2

Then the line is like:

y = -2*x + b

And we know that this passes through (10, 5), replacing these values:

5 = -2*10 + b

5 = -20 + b

5 + 20 = b

25 = b

D) The term "imaginary roots" describes the roots of the equation 3x2 - 4x + 5 = 0 the best.

The formula is the quadratic equation ax2 + bx + c = 0 in standard form.

x = [-b ± √(b2 - 4ac)]

/ 2a

It follows that

3x2 - 4x + 5 = 0

Here, an equals 3, b equals -4, and c equals 5.

Using these numbers as replacements in the formula

x = [-(-4) ± √((-4)2 - 4 × 3 × 5)]

/ (2 × 3)

By even more simplifying

x = [4 ± √(16 - 60)]

x = [4 ± √-44]/ 6

As a result,

x = [4 ± 2√-11]/ 6

x = [2 ± I √11]/ 3

Answer: The Declaration of Independence, adopted by the Continental Congress on July 4, 1776, is a reflection of the colonists' motivations in several ways. Firstly, the Declaration states that the colonists believed that all men are created equal and have the right to life, liberty, and the pursuit of happiness. This reflects the colonists' belief in the Enlightenment principles of natural rights and individual liberty, which were influential in shaping their motivations for seeking independence from British rule.

Secondly, the Declaration cites a long list of grievances against King George III, accusing him of violating the colonists' rights and abusing his power. This reflects the colonists' growing frustration and anger towards British rule, which had been building for many years prior to the drafting of the Declaration.

Thirdly, the Declaration states that the colonists had attempted to resolve their differences with the British government through peaceful means, but that these efforts had been unsuccessful. This reflects the colonists' desire for a peaceful resolution to their issues, but their willingness to fight for their rights if necessary.

In summary, the Declaration of Independence reflects the colonists' belief in natural rights and individual liberty, their growing frustration and anger towards British rule, and their desire for a peaceful resolution to their issues but their willingness to fight for their rights if necessary.

Yes 360 degrees is full turn calling it a full rotation.

A degree is the name given to the mathematical unit of measurement for an angle. A protractor is a device used to determine the degree of an angle. Angles can be measured at different angles with different degrees, such as 30°, 45°, 60°, and so on. A complete circle rotates at 360°.

Each of the 360 equal segments that make up a rotation is referred to as a degree. We use a circle ° to represent a degree. 180°, for instance, denotes 180 degrees. An angle in degrees is an angle whose measure is expressed in degrees.

A 360 degree is also called as a Complete angle because it complete the whole round making the 180 degree angle twice giving us 360 degree.

Answer:

The equation x2+6x+9 = 0 has roots of 3+i and 3-i. By the fundamental theorem of algebra, this equation has three roots, two of which may be equal. The standard quadratic equation using the given set of solutions {3+i,3-i} is y=x2+6x+9.

Answer:

x = 79

Step-by-step explanation:

Since PQ and RS are most likely parallel lines, we can consider the orange angles (image provided below) to be similar due to them being alternate interior angles.

Now that we know that one angle of the triangle given (orange) is 46 degrees, we can solve for the other angle of the triangle. A triangle adds up to 180 degrees, so we can find the missing angle by subtracting 180 from the given angles: 180-33-46 = 101 (marked in red).

With the red angle, we can find x by subtracting 180 from 101. Why you may ask? Because RS is parallel to PQ, so the degree will be 180. Therefore, the missing angle, x, will be 79.

x/sin 45 = 4√22/sin 90

CB = 4√22/sin 90 × sin 45

CB = 4√11

or

CB = √(4√22)²-(4√11)²

= 4√11

Answer:

CB = AC = 4√11

Step-by-step explanation:

We know that the sum of the angles of a triangle is 180°. If angle A = 45° and C = 90°, then angle B = 180° - 90° - 45° = 45°. This shows us that the triangle is isosceles and the leg AC is equal to the leg CB.

Consequently: CB = AC = 4√11

If we didn't know the length of AC, then it can be calculated from the hypotenuse:

AC² + CB² = AB²
2 * CB² = (4√22)²
CB² = (4√22)² / 2
CB² = 16 * 22 / 2
CB = √(16 * 11)
CB = 4√11

Amelia cut a 168 inch long ribbon into 6 equal part. Patrick cut a 14 foot long ribbon into 7 equal piece.

Amelia's ribbon pieces were 28 inches long each. Patrick's ribbon pieces were 2 feet long each.

Amelia's ribbon:

To calculate how long each piece of ribbon is, we need to divide 168 inches (the total length of the ribbon) by 6 (the number of pieces).

168 ÷ 6 = 28

Therefore, Amelia's ribbon pieces were 28 inches long each.

Patrick's ribbon:

To calculate how long each piece of ribbon is, we need to divide 14 feet (the total length of the ribbon) by 7 (the number of pieces).
