Standard equation of an ellipse is :
[tex]\qquad \rm\dashrightarrow \: \dfrac{ {(x - h)}^{2} }{ {a}^{2} } + \dfrac{ {(y - k)}^{2} }{ {b}^{2} } = 1[/tex]
If b is smaller than a, then it will be a horizontal ellipse, and if b is greater than a, it will be a vertical ellipse. and shifting depends upon coordinates of its centre.
Now, our given equation is :
[tex]\qquad \rm\dashrightarrow \: \dfrac{ {x}^{2} }{ 15 } + \dfrac{ {y }^{2} }{ {10} } = 1[/tex]
[tex]\qquad \rm\dashrightarrow \: \dfrac{ {x}^{2} }{ {(\sqrt{15})}^{2} } + \dfrac{ {y}^{2} }{ {(\sqrt{10}) {}^{2} } } = 1[/tex]
[ here, b = root 10 and a = root 15, hence a is greater than b here, which means : its a horizontal ellipse.
And since it is a horizontal ellipse with center at origin, it's major axis will lie on x - axis.

Answers
The correct choice is: If A is the given matrix then the augmented matrix presents the equation Ax = 0. The reduced echelon form of this matrix indicates that Ax = 0 has only the trivial solution. Therefore the columns of A do not form linearly independent set.
To determine if the columns of the matrix form a linearly independent set, we can perform row reduction on the matrix and examine the resulting reduced row echelon form.
The given matrix is:
[0 3 9]
[2 -7 -1]
[1 -4 -2]
[0 3 9]
[2 -7 -1]
[1 -4 -2]
R2 = R2 - 2R1
R3 = R3 - R1

R2 = R2 + 7/3 R3
[0 3 9]
[2 0 20/3]

R1 = R1 - 3/2 R2
R3 = R3 + 4R2
[0 3 0]
[2 0 20/3]

R1 = R1 / 3
R2 = R2 / 2
R3 = R3 / 3
[0 1 0]
[1 0 10/9]
[1 0 2/9]
The resulting reduced row echelon form shows that the third column is a linear combination of the first and second columns. Specifically, column 3 can be expressed as:
(2/9)*column 1 + (10/9)*column 2 = column 3
Since the third column can be expressed as a linear combination of the first and second columns, the columns of the matrix do not form a linearly independent set.
Therefore, the correct choice is:
If A is the given matrix then the augmented matrix presents the equation Ax = 0. The reduced echelon form of this matrix indicates that Ax = 0 has only the trivial solution. Therefore the columns of A do not form linearly independent set.

The expansion of (2x+3y) ∧ 6 will contain 7 terms.

To see why, consider the binomial theorem, which tells us that the expansion of [tex](a + b) ^n[/tex] will have (n+1) terms, where the first term has coefficient 1 and the last term has coefficient 1.
In the case of [tex](2x+3y)^ 6[/tex], we can think of this as the expansion of [tex](2x + 3y) ^6 as (2x) ^ 6 + 6(2x) ^ 5(3y) + 15(2x) ^ 4(3y) ^ 2 + 20(2x) ^ 3(3y) ^3 + 15(2x) ^2(3y) ^ 4 + 6(2x)(3y) ^5 + (3y) ^6.[/tex]

The area of the figure composed of the square and four semicircles is approximately 242.4 square units.
Describe Semicircle?A semicircle is a two-dimensional geometric shape that is half of a circle. It is formed by drawing a diameter of a circle and then drawing the arc that connects the two endpoints of the diameter. The diameter divides the circle into two equal parts, each of which is a semicircle.
A semicircle has several important properties, including:
It has one straight side, which is the diameter of the circle.
The other side is curved, and it is a half-circle.
The radius of the semicircle is equal to half the diameter of the circle.
The circumference of a semicircle is half the circumference of the circle.
The area of a semicircle is half the area of the circle.
Semicircles are used in many applications of geometry and trigonometry, including in the study of angles, arcs, and circles. They are also used in architecture and engineering to design buildings, bridges, and other structures that have semicircular features.
In addition to being a geometric shape, a semicircle can also refer to a half-circle that is used as a decorative element or design motif. Semicircles are often used in art, architecture, and graphic design to create visually interesting patterns and compositions.
To find the area of the figure composed of a square and four semicircles, we need to first find the area of the square and the area of the four semicircles. Then, we can subtract the area of the four semicircles from the area of the square to get the total area of the figure.
The area of the square is simply the side length squared, so in this case it is:
Area of square = (22)^2 = 484 square units
The diameter of each semicircle is equal to the side length of the square, so the radius is half of that or 11 units. Therefore, the area of each semicircle is:
Area of semicircle = (1/2) * π * r^2 = (1/2) * π * 11^2 = 60.4 square units
Since there are four semicircles, the total area of the four semicircles is:
Total area of semicircles = 4 * Area of semicircle = 4 * 60.4 = 241.6 square units
To get the area of the entire figure, we need to subtract the area of the four semicircles from the area of the square:
Area of figure = Area of square - Total area of semicircles
Area of figure = 484 - 241.6 = 242.4 square units
Rounding this to the nearest tenth gives:
Area of figure = 242.4 (rounded to the nearest tenth)
Therefore, the area of the figure composed of the square and four semicircles is approximately 242.4 square units.

You kayak up a river at a rate of 168 feet every 2 minutes. You kayak 56 feet every 30 seconds on the way back down the river. How much farther do you kayak in 5 minutes on the way down the river than in 5 minutes on the way up the river?
Answers
You kayak 140 feet further in 5 minutes going downstream than you do in 5 minutes going upstream.
Relationship Between Speed, Time & Distance:Speed is determined by dividing the distance traveled by the time taken to travel it. It gives the distance traveled and the amount of time it took to travel that distance.
Speed is directly Proportional to Distance and Inversely proportional to Time. Hence,
Distance = Speed X Time.
Given: You paddle a kayak 168 feet up a river every two minutes.
Hence, 168/2 = 84 feet per minute.
Therefore you go up 84 feet in one minute.
You reach 84*5 = 420 feet in 5 minutes.
Given: As you paddle back down the river, you cover 56 feet every 30 seconds.
Speed is determined by distance traveled divided by time, therefore when traveling downward, 56/0.5 equals 112 feet per minute.
In one minute, you descend by 112 feet.
You descend 560 feet in 5 minutes, or 5*(112) feet.
As a result, you will move on 140 feet (560 - 420)=140 feet further .

find the critical value that corresponds to the confidence level %.
Answers
The critical value, zα/2, that corresponds to a 87% confidence level is approximately 1.514.
The critical value, zα/2, is the z-score that cuts off an area of α/2 in the tails of the standard normal distribution. In other words, it represents the number of standard deviations away from the mean that corresponds to a particular level of confidence.
To find the critical value for a 87% confidence level, we first need to determine the area that is left in the tails of the distribution. Since the confidence level is 87%, the area in the middle of the distribution is (1 - 0.87) = 0.13. We then divide this area in half to get the area in each tail, which is 0.065.
Using a standard normal distribution table or a calculator, we can find that the z-score that cuts off an area of 0.065 in one tail is approximately 1.514. Therefore, the critical value, zα/2, is:
zα/2 = ±1.514
However, since we want to find the z-score that corresponds to the middle 87% of the distribution, we need to add the absolute value of this number to the mean of the distribution, which is 0. This gives us:
zα/2 = |1.514| = 1.514

A boat travels 15 miles upstream and then turns around and travels 15 miles downstream. The total time for both trips is 4 hours. If the stream flows at 5 miles per hour, how fast does the boat travel in still water?
Answers
If the boat needed to travel 15 miles there and back, while the stream only moves 5 miles per hour, it would take 3 hours to travel there and back. This means that in still water, the boat would take 6 hours to move 15 miles upstream and back.
what is 5 8 as a decimal
Answers
The number 5/8 as a decimal is 0.625
As we divide a whole into smaller parts, we get decimals. Hence, there are two parts to a decimal number: a whole number part and a fractional part. The whole component of a decimal number has the same decimal place value system as the complete number. After the decimal point, however, when we proceed to the right, we obtain the fractional portion of the decimal number.
An informal way to read a decimal is to first read the whole number as you would any whole number, then the decimal point as "point," and finally each individual digit of the rational part.
