So, the correct answer is: Major Axis: 12[tex]\sqrt{2}[/tex] units, Minor Axis: 24 units.

An ellipse is a closed curve that is symmetrical about two axes, commonly referred to as the major axis and minor axis. It can be described as a stretched circle or a flattened oval. The shape of an ellipse can be defined by two focal points (also known as foci) and the distance between them. Any point on the ellipse is the sum of the distances between that point and each focus. Ellipses have a wide range of applications in mathematics, physics, astronomy, and engineering. They are used to describe the orbits of planets and other celestial bodies, to design reflectors and lenses for telescopes, and to create art and design elements.

The standard equation of an ellipse centered at the origin is given by:

[tex](x^2/a^2) + (y^2/b^2) = 1,[/tex]

where "a" and "b" are the lengths of the semi-major and semi-minor axes, respectively. To find the lengths of the major and minor axes of the given ellipse, we need to first put it in standard form by dividing both sides by 12:

[tex]x^2/72 + y^2/144 = 1[/tex]

Comparing this with the standard form, we see that.[tex]a^2 = 72[/tex]and b^2 = 144. Thus, the lengths of the semi-major and semi-minor axes are:

a = [tex]\sqrt{72}[/tex] = 6[tex]\sqrt{2}[/tex] units

b = [tex]\sqrt{144}[/tex]= 12 units

Therefore, the lengths of the major and minor axes of the ellipse are:

Major Axis: 2a = 2(6[tex]\sqrt{2}[/tex]) = 12[tex]\sqrt{2}[/tex]units

Minor Axis: 2b = 2(12) = 24 units

So, the correct answer is: Major Axis: 12[tex]\sqrt{2}[/tex] units, Minor Axis: 24 units

the submarine is approximately 2.236 kilometers from its starting point.

Distance is a numerical measurement of the space between two points. It is the length of the path traveled by an object moving from one point to another, regardless of the direction it takes. Distance is typically measured in units such as meters, kilometers, feet, miles, or any other unit of length.

The submarine is essentially moving in a square pattern, with sides of length 1 km. Each time it moves north or west, it changes its distance from the starting point by 1 km.

Since the submarine moves 1 km north and 1 km west in each "leg" of its journey, it will complete 20 legs before traveling a total of 40 km. At this point, it will be 1 km north and 1 km west of its starting point.

The 21st and final leg of the journey brings the submarine 1 km north, so it ends up 2 km north and 1 km west of its starting point. Using the Pythagorean theorem, we can find the distance between the starting point and the final position of the submarine:

d = √((2 km)² + (1 km)²)

=√(5) km

≈ 2.236 km

Therefore, the submarine is approximately 2.236 kilometers from its starting point.

The dimensions of the box are 30 cm by 50 cm by 25 cm.

Area is a measure of the amount of space enclosed by a two-dimensional object, such as a shape or a surface. It is usually expressed in square units, such as square meters (m²), square inches (in²), or square centimeters (cm²), depending on the unit system used.

Let x be the side length of the squares that are cut out of each corner of the cardboard.

When the squares are cut out and the sides are folded up, the resulting box will have dimensions (80-2x) cm by (100-2x) cm by x cm.

The area of the base of the box is:

(80-2x) cm × (100-2x) cm = 8000 - 360x + 4x² cm²

We know that the area of the base is 4000 cm², so we can set this equal to the expression we just found:

8000 - 360x + 4x² cm² = 4000 cm²

Simplifying and rearranging, we get a quadratic equation:

4x² - 360x + 4000 = 0

Dividing both sides by 4, we get:

x² - 90x + 1000 = 0

This quadratic can be factored as:

(x - 40)(x - 25) = 0

Therefore, the possible values of x are x = 40 cm and x = 25 cm.

If we use x = 40 cm, then the dimensions of the box are:

Length = 80 - 2x = 0 cm (not possible)

Width = 100 - 2x = 20 cm

Height = x = 40 cm

If we use x = 25 cm, then the dimensions of the box are:

Length = 80 - 2x = 30 cm

Width = 100 - 2x = 50 cm

Height = x = 25 cm

Therefore, the dimensions of the box are 30 cm by 50 cm by 25 cm.

Using the proportionality theorem we know that the length of the side AE is 28 units respectively.

The intercept theorem often referred to as Thales' theorem, the basic proportionality theorem, or the side splitter theorem is a crucial concept in introductory geometry that deals with the ratios of different line segments produced when two intersecting lines are intercepted by a pair of parallels.

A triangle's other two sides are divided in the same proportion if a line drawn parallel to either one of its sides intersects the other two sides at two different spots.

So, the given proportion is:

= 32/56

= 4/7

Then,

= AE/49

We will be using table 7:

Answer:

87.1 degrees

Step-by-step explanation:

First, you know the sum of the angles is 180 degrees. So, 5x+4x+10+10x-5=180.

Then, simplify to 19x+5=180. So, 19x=175. That means by dividing both sides by 19 x is approximately 9.21.

Finally, plug in x into angle 3.

10x9.21-5

=92.1-5

=87.1

So, the third angle is approximately 87.1.

Answer:

An exponential function can be used to model this situation.

In this case, we know that each hour following the initial dose, 80% of the concentration remains in the body from the preceding hour. This means that the amount of penicillin remaining in the body is decreasing exponentially.

We can use the formula for exponential decay, which is:

A = A0 * e^(-kt)

where A is the amount of penicillin remaining in the body at time t, A0 is the initial amount of penicillin (in this case, 500 milligrams), k is the decay constant, and e is the mathematical constant approximately equal to 2.718.

The decay constant, k, can be calculated using the following formula:

k = ln(0.8)

where ln is the natural logarithm.

So the exponential function that can be used to model this situation is:

A = 500 * e^(-0.2231t)

where t is the time in hours since the initial dose was administered.

This function will give us the amount of penicillin remaining in the body at any time t, based on the initial dose and the rate of decay.

The volume of the sphere is approximately 33.51 cubic centimeters.

The volume of a sphere can be calculated using the formula:

V = (4/3)π[tex]r^{3}[/tex]

where r is the radius of the sphere

V is the volume of the sphere

Since the diameter of the sphere is 4 centimeters, the radius is half of that, or 2 centimeters.

Plugging this value into the formula, we get:

V = (4/3)π([tex]2^{3}[/tex])

V = (4/3)π(8)

V = (32/3)π

So the answer is (a)  32/3π[tex]cm^{3}[/tex]

the volume of the sphere is approximately 33.51 cubic centimeters.

The volume of the sphere is a measure of how much space the sphere occupies. The formula for the volume of the sphere tells us that the volume is proportional to the cube of the radius. This means that as the radius increases, the volume of the sphere increases much more rapidly. This is why a small increase in the radius can result in a much larger increase in the volume of the sphere.

We can conclude after answering the provided question that Therefore, diameter m GFH = 21° and m GZH = 116°.

In geometry, the diameter of a circle is any straight line segment that has an endpoint on the circle and travels through its centre. Another way to put it is the longest chord of a circle. Either concept can be used to define the diameter of a sphere. The diameter is the length of the line that runs tangent to the two points at either end of the circle. If you consider length to be the distance between two points, diameter equals length. The diameter of a circle is the distance between its two furthest points.

We know that angle EGF is a right angle (90°) because EG is a diameter.

Given that m FG = 116°, we can calculate m FGE by subtracting it from 180° (the sum of triangle angles):

m FGE = 180 degrees - m FG = 180 degrees - 116 degrees = 64 degrees

m GFH = 180° - m ZGF - m ZGFH = 180° - 90° - 69° = 21°

Finally, we can calculate m GZH by subtracting m FGE from 180° (the sum of triangle angles):

180° m GZH - 180° m FGE - 64° = 116°

Therefore, m GFH = 21° and m GZH = 116°.

The answer is  option (A)  BC=YZ ,to show that AABC = AXYZ by ASA, we need to know that angle C is congruent to angle ∠Y, angle ∠Z is congruent to angle ∠B, and BC is congruent to ZY.

An angle is a geometric figure formed by two rays with a common endpoint, called the vertex of the angle. The two rays are called the sides of the angle, and they can be named in any order. The measure of an angle is the amount of rotation needed to bring one of the rays into alignment with the other.

To show that AABC = AXYZ by ASA, we need to show that two angles and the included side of one triangle are congruent to two angles and the included side of the other triangle. Since we are given that ZZZC and CB ZY, we know that angle ∠C is congruent to angle ∠Y, and angle ∠Z is congruent to angle ∠B. Therefore, we need to find another piece of information that shows that the included sides are congruent.

Looking at the diagram, we can see that side BC is congruent to side ZY, since they are opposite sides of a rectangle. Therefore, we have BC = ZY, which means that statement A, BC=YZ, is true.

So, to show that AABC = AXYZ by ASA, we need to know that angle ∠C is congruent to angle ∠Y, angle ∠Z is congruent to angle ∠B, and BC is congruent to ZY. Since we have all three of these conditions, we can conclude that AABC = AXYZ by ASA.

Step-by-step explanation:

44h=616$

1h=44h divided by 44

=616$ divided by 44

= 14

150% of 14$ = 100% + 50%

= 14$ + 7$

= 21$

826$-616$ = 210$

1h(additional hour rate) =21$

10h= 210$

44h + 10h = 54h = 826$

Therefore , the solution of the given problem of  equation comes out to be for 0 brothers, 78°, for 1 brother, 132°, for two brothers, 66°,for 3 brothers, 42° and for 4 brothers, 42°.

A linear recovery model is founded on the formula: y=mx+b. B is the slope, and m is the y-intercept. The phrase "Bivariate logistic formulas have two components" is frequently used, despite the fact that y and y are two separate elements. When it comes to using linear functions, there are no easy solutions. and. Y=mx+b is the expression, where m stands for slopes and b for the y-intercept.

Here,

(Frequency  Total Frequency) x 360 equals angle (0).

the aggregate of all frequencies is the total frequency.

We can see from the provided chart that:

13 individuals lack relatives.

22 individuals each have one sibling.

11 individuals have two siblings, and 7 people have three.

7 individuals have 4 brothers.

13 + 22 + 11 + 7 + 7 = 60 is the overall frequency.

Using the aforementioned method, we can now determine the angle for each category:

For 0 siblings: Angle = (13 ÷ 60) x 360 = 78°

For 1 sibling: Angle = (22 ÷ 60) x 360 = 132°

For 2 siblings: Angle = (11 ÷ 60) x 360 = 66°

For 3 siblings: Angle = (7 ÷ 60) x 360 = 42°

For 4 siblings: Angle = (7 ÷ 60) x 360 = 42°

The total of all angles ought to

All the angles should total up to 360 degrees, which we can verify by:

78° + 132° + 66° + 42° + 42° = 360°

Therefore, the angles needed to represent the number of siblings among 60 individuals on a pie chart are:

for 0 brothers, 78°

for 1 brother, 132°

For two brothers, 66°

for 3 brothers, 42°

for 4 brothers, 42°

The value of m∠Q is 148°.

What is tangent?

The straight line that "just touches" the curve at a given location is referred to as the tangent line to a plane curve in geometry. It was described by Leibniz as the path connecting two points on a curve that are infinitely near together.

Here, we have

Given: PR is ranger to circle Q at Point R. PS is tangent to circle Q at Point S.

We have to find the value of m∠Q.

We know that PR = PS

In ΔPRS

∠P + ∠R + ∠S = 180°

∴ ∠R = ∠S

∠P + ∠R + ∠R = 180°

38 + 2∠R  = 180°

2∠R  = 180° - 32°

2∠R = 148°

∠R  = 74°

∠S =  74°

∠PRQ = 90°

In ΔSRQ

∠SRQ = 90° - 74° = 16°

∠RSQ = 90° - 74° = 16°

∴ ∠SRQ + ∠RSQ + ∠RQS   = 180°

16° + 16° +∠RQS = 180°

∠RQS = 180° - 32°

∠RQS = 148°

m∠Q = 148°

Hence, the value of m∠Q is 148°.

The average distance between each data value and the data set's mean is represented by the mean absolute deviation of the data set's 3, 7, 10, 12, and 15 values, which is 3.24. It provides a measurement of the variance or departure from the mean of the data values.

The term "absolute" refers to the distance a number is from 0 on a number line. The absolute value of a number is always positive and represents the magnitude of the number regardless of its sign. For example, the absolute value of -5 is 5, and the absolute value of 5 is also 5.

The distance between two points on number line is always the absolute value of the difference between those points. Hence distance a number is from 0 on a number line is always the absolute value of that number.

To deviate means to differ or vary from a standard or expected value. The mean absolute deviation of a data set is the average (mean) distance from each data value to the mean of the data set. It measures how spread out the data values are from the mean.

For example, consider the data set {3, 7, 10, 12, 15}. The mean of this data set is (3 + 7 + 10 + 12 + 15)/5 = 9.4. To calculate the mean absolute deviation, we need to find the absolute deviation of each data value from the mean, then take the mean of those absolute deviations.

The absolute deviations from the mean are:

|3 - 9.4| = 6.4

|7 - 9.4| = 2.4

|10 - 9.4| = 0.6

|12 - 9.4| = 2.6

|15 - 9.4| = 5.6

The mean absolute deviation is the average of these absolute deviations:

(6.4 + 2.4 + 0.6 + 2.6 + 5.6)/5 = 3.24

If the standard deviation is 12,000 dollars for four electricians, then the standard deviation for the sampling distribution of the sample mean is 6000 dollars.

The standard deviation of the sampling distribution of the sample mean, is also known as the standard error of the mean,

The standard deviation is be calculated using the formula,

⇒ standard-error of mean is = σ/√n,

Where σ = population standard deviation and n = sample size,

In this case, σ = 12,000 dollars and n = 4.

Substituting these values into the standard deviation formula, we get,

⇒ "standard-error" of mean = 12000/√4 = 6,000 dollars.

Therefore, the standard deviation for the sampling distribution of the sample mean is 6,000 dollars.

What is the standard deviation for the sampling distribution of the sample mean?

Step-by-step explanation:

To find the vertical asymptotes of the function f(x) = (x^2+3x+6)/(x^2-4), we need to find the values of x that make the denominator equal to zero.

The denominator (x^2-4) factors into (x+2)(x-2). Therefore, the denominator is equal to zero when x = -2 or x = 2.

These values of x give us vertical asymptotes since the function becomes unbounded as x approaches these values. Therefore, the vertical asymptotes of the function are x = -2 and x = 2.

An equation of the line that passes through the points (-7, 7) and (−2, −6) in point-slope form is y - 7 = -13/5(x + 7).

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁) or [tex]y - y_1 = \frac{(y_2- y_1)}{(x_2 - x_1)}(x - x_1)[/tex]

Where:

At data point (-7, 7), a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:

[tex]y - y_1 = \frac{(y_2- y_1)}{(x_2 - x_1)}(x - x_1)\\\\y - 7 = \frac{(-6- 7)}{(-2 -(-7))}(x -(-7))\\\\y - 7 = \frac{(-6- 7)}{(-2 +7)}(x +7)[/tex]

y - 7 = -13/5(x + 7)

y = -13x/5 + 7 - 91/5.

y = -13x/5 - 56/5

In this context, we can reasonably infer and logically deduce that an equation of the line that represents this line in slope-intercept form is y = -13x/5 - 56/5.
