The measurements in order of size, starting with the smallest are: 2.3 mm, 24 mm, 2.3 cm, 21 cm, and  0.2 m.

Given the measurements in the question;

2.3 cm, 24 mm, 0.2 m, 21 cm, 2.3 mm​

To arrange the measurements in order of size, we need to convert them to a common unit of measurement.

We can convert all the measurements to meters, as it is the largest unit given.

Hence;

2.3 mm = 2.3 ÷ 1000 =  0.0023 m

24 mm = 24 ÷ 1000 = 0.024 m

21 cm = 21 ÷ 100 = 0.21 m

2.3 cm = 2.3 ÷ 100 =  0.023 m

0.2 m = 0.2 m

Now that all the measurements are in meters, we can compare them:

0.0023 m < 0.024 m < 0.023 m < 0.21 m < 0.2 m

Therefore, the measurements in order of size, starting with the smallest, are:

2.3 mm < 24 mm < 2.3 cm < 21 cm < 0.2 m

The rent of the apartment during the 9th year of living in the apartment would be approximately $3,510.45 per month.

If the rent starts at $1600 per month and increases by 9.5% each year, then we can use the formula for compound interest to calculate the rent after 9 years.

The formula for compound interest is:

A = P(1 + r/n)^(nt)

where:

A is the final amount

P is the initial principal (the starting amount)

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the number of years

In this case, P = $1600, r = 9.5% = 0.095, n = 1 (compounded once per year), and t = 9. We want to find A, the rent after 9 years.

A = 1600(1 + 0.095/1)^(1×9)

A = 1600(1.095)^9

A ≈ $3,510.45

2+3x=12-5x

2-12=-5x-3x

-10=-8x

x=10/8=5/4

Answer:

x = 5/ 4

Step-by-step explanation:

The cοοrdinates οf pοint B are (4, 0) and the cοοrdinates οf pοint C are (8, 16/3) οr (-4, -16).

We can use the fοrmula fοr the area οf a triangle, which is:

area = (base * height) / 2

We knοw that the base AB has a length οf 16 units, sο we can find the height by rearranging the fοrmula:

height = (2 * area) / base

height = (2 * 80) / 16

height = 10

Sο, pοint B is at (4, 0) and pοint C is at (x, y) where the height frοm A tο BC is 10 units and the length οf BC is 16 units.

We can use the Pythagοrean theοrem tο find the cοοrdinates οf pοint C:

[tex]x^2 + y^2 = BC^2[/tex]

[tex]x^2 + y^2 = 16^2[/tex]

[tex]x^2 + y^2 = 25[/tex]

Alsο, we knοw that the height frοm A tο BC is 10 units, sο the distance between pοint A and the line BC is 10 units. The slοpe οf the line BC is -y/x (rise οver run), sο the equatiοn οf the line BC is:

[tex]y = (-y/x) * (x - 4)[/tex]

[tex]y = (-y/x) * x + (y/x) * 4[/tex]

[tex]y + (y/x) * x = (y/x) * 4[/tex]

[tex]y(x/x + 1) = (y/x) * 4[/tex]

[tex]y + x = 4y/x[/tex]

[tex]x^2 + xy = 4y[/tex]

[tex]y = (x^2) / (4 - x)[/tex]

The statement "rotated an angle whose measure is more than halfway around a circle" is incorrect. An angle whose measure is 60 degree is rotated more than halfway around a circle.

A rotated angle is an angle that has been moved or transformed from its original position, while an angle that measures more than halfway around a circle is called a reflex angle. A reflex angle measures between 180 and 360 degrees, which means that it has rotated more than halfway around a circle.

In contrast, an angle that measures less than 180 degrees is called an acute angle, while an angle that measures exactly 180 degrees is called a straight angle. Understanding the different types of angles is important in geometry and mathematics.

Answer:

Step-by-step explanation:

We can use the concept of speed, distance, and time to solve the problem.

Let's assume that the bird was flying at a constant speed of "x" miles per minute.

When the bird passed the first building, Tim started the stopwatch. Let's say the time on the stopwatch was "t" minutes.

Therefore, the bird had flown a distance of "x*t" miles when Tim started the stopwatch.

In the next minute, the bird flew another 0.5 miles (the distance between the two buildings). So, the total distance traveled by the bird was:

x*t + 0.5 miles

We know that the total time elapsed was 1 minute. Therefore:

t + 1 = total time elapsed

Now, we can use these equations to solve for the speed of the bird:

x*t + 0.5 = distance traveled

t + 1 = total time elapsed

We want to find the value of x, so we can solve for t:

t = total time elapsed - 1

Substituting this value of t into the first equation, we get:

x*(total time elapsed - 1) + 0.5 = distance traveled

Simplifying, we get:

x*(total time elapsed) = distance traveled + 0.5

Substituting the given values, we get:

x*(1) = 0.5 + x*t

x = 0.5 + x*(total time elapsed - 1)

x = 0.5 + x*(59/60)

Solving for x, we get:

x = 30 miles per hour

Therefore, the bird was flying at a speed of 30 miles per hour.

The missing measurements of the triangle given include:

The value of angle B can be found thanks to the knowledge that the interior angles of a triangle add up to 180 degrees and we have two of the angle measurements :

= 180 - angles measurements

= 180 - 27 - 90

= 63 degrees

The value of AB can be found by using the Sin theta operation such that:

Sin theta = Opposite / hypotenuse

Sin ( 27 degrees ) = 12 / hypotenuse which is AB

hypotenuse = 12 / ( Sin ( 27 degrees ))

= 26 .4 units

(16) The value of x makes the expression equal to 0 is -2i. (option B).

The value of x is calculated by solving the equation as follows;

(15) We have the equation:

√x = 14i√3

Squaring both sides, we get:

x = (14i√3)^2

x = -588

(16) Factoring the expression, we get:

x(x⁴ + 6x² + 8)

Setting each factor equal to 0, we get:

x = 0 or x⁴ + 6x² + 8 = 0

Let's solve for the second equation:

Let y = x²

Then we have:

y² + 6y + 8 = 0

Factorizing, we get:

(y + 2)(y + 4) = 0

So y = -2 or y = -4

Since y = x², this means:

x² = -2 or x² = -4

Taking the square root of both sides, we get:

x = ±√(-2) or x = ±√(-4)

Simplifying using imaginary numbers, we get:

x = ±i√(2) or x = ±2i

Thus, for the expression √x is equivalent to 14i√3,  the value of x is -588. And for the expression x⁵ + 6x³ + 8x, x = -2i.

Answer: To find the rational roots of f(d) = 5d^3 - 6d^2 + d - 8, we can use the Rational Root Theorem, which states that any rational root of a polynomial equation must be of the form p/q, where p is a factor of the constant term (in this case, -8) and q is a factor of the leading coefficient (in this case, 5).

The factors of -8 are ±1, ±2, ±4, and ±8, and the factors of 5 are ±1 and ±5. Therefore, the possible rational roots of f(d) are:

±1/1, ±2/1, ±4/1, ±8/1, ±1/5, ±2/5, ±4/5, and ±8/5

We can try these values one by one to see if they are roots of f(d). For example, when we try d = 1, we get:

f(1) = 5(1)^3 - 6(1)^2 + 1 - 8 = 5 - 6 + 1 - 8 = -8

Since f(1) is not equal to zero, d = 1 is not a root of f(d). We can continue this process until we find all the rational roots of f(d).

Step-by-step explanation:

using graph f(x) is concave down on (-1,0), (1,∞).

What is derivative?

A function's varied rate of change with respect to an independent variable is referred to as a derivative. When there is a variable quantity and the rate of change is irregular, the derivative is most frequently utilized. The derivative is used to assess how sensitive a dependent variable is to an independent variable (independent variable). In mathematics, a quantity's instantaneous rate of change with respect to another is referred to as its derivative. Investigating the fluctuating nature of an amount is beneficial.

f(x) is concave up where f'(x) is increasing and concave down where f'(x) is decreasing

So, using graph f(x) is concave down on (-1,0), (1,∞).

Hence, using graph f(x) is concave down on (-1,0), (1,∞).

Life expectancy is the average number of years that a person is expected to live, based on statistical data and various demographic factors such as age, gender, health status, lifestyle, and environmental conditions. It is usually calculated from birth and is a useful indicator of the overall health and well-being of a population.

Life expectancy can vary widely between different countries and regions, as well as between different demographic groups within a population. Factors that can influence life expectancy include access to healthcare, nutrition, education, economic development, social support, and public health policies.

To estimate the life expectancy for someone born in 2005, we need to use the line of best fit equation:

y = 0.40x - 716.91

where x is the birth year and y is the corresponding life expectancy.

To find the estimated life expectancy for someone born in 2005, we substitute x = 2005 into the equation:

Since the first person chosen is a boy, there are now 12 boys and 15 girls left in the class. We want to find the probability that the second person chosen is also a boy.

The probability of choosing a boy for the first selection is 13/28. Then, for the second selection, there are now 12 boys and 27 students left, so the probability of choosing a boy is 12/27.

Using conditional probability, we can calculate the probability that the second person chosen is also a boy given that the first person chosen is a boy:

P(Second person is a boy | First person is a boy) = P(Both are boys) / P(First person is a boy)

P(Second person is a boy | First person is a boy) = (12/27) / (13/28)

P(Second person is a boy | First person is a boy) ≈ 0.872

Step-by-step explanation:

To determine whether two lines are parallel, we need to compare their slopes. If the slopes are equal, then the lines are parallel.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

A) x − 5y = 10 can be rearranged to y = (1/5)x − 2, so its slope is 1/5.

y = 5x – 2 is already in slope-intercept form, so its slope is 5.

These two slopes are not equal, so the lines are not parallel.

B) x + y = 0 can be rearranged to y = −x, so its slope is −1.

y = x + 7 is already in slope-intercept form, so its slope is 1.

These two slopes are not equal, so the lines are not parallel.

C) 2x − 3y = 9 can be rearranged to y = (2/3)x − 3, so its slope is 2/3.

4y = 6x − 20 can be rearranged to y = (3/2)x − 5, so its slope is 3/2.

These two slopes are not equal, so the lines are not parallel.

D) 4x + 8y = 8 can be rearranged to y = −(1/2)x + 1, so its slope is −1/2.

y = 2x + 2 is already in slope-intercept form, so its slope is 2.

These two slopes are not equal, so the lines are not parallel.

E) 9x − 3y = 12 can be rearranged to y = 3x − 4, so its slope is 3.

y = 3x − 10 is already in slope-intercept form, so its slope is 3.

These two slopes are equal, so the lines are parallel.

Therefore, the pair of lines that are parallel is (E) 9x - 3y = 12; y = 3x - 10.
