The data and the image both characterize the object as a rectangle because its length is 12 and its width is 9.

A quadrilateral having four right angles, or rectangle, in Euclidean plane geometry. A quadrilateral that is equiangular, or one in which all of the angles are equal, is another way to describe it. Also possible is a straight angle in the parallelogram. With four sides that are of the same size, a square is a rectangle. Four 90-degree vertices and equal parallel sides make up a quadrilateral with a rectangle-like shape. Its equirectangular rectangle moniker derives from this. The term "parallelogram" also refers to a rectangle, which has equal and parallel opposite sides.

The last option which says  the roots of the auxiliary equation are √6 and -√6 is the correct one.

Auxiliary equation is the equation of characteristic polynomial which is calculated by substituting the right member of a standard differential equation by zero.

The roots of the equation is helpful in determining the nature of the general solution of the given differential equation.

We have the differential equation given in the question,

d²y / dx²  - 6y = 0

Now we can replace d²y / dx² as y''.

y'' - 6y = 0, where y'' is the second derivative of y.

Now we have to find the roots of the auxiliary equation.

Let c = y', then c² = y''

c² - 6 = 0

c² = 6

c = +√6 and -√6

So the roots of the equation are √6 and -√6.

Hence the roots of the auxiliary equation of the differential equation given are +√6 and -√6.

The angle measure of the circle graph is as follows:

A travel magazine surveyed 500 of its adult readers about their favourite ways to travel. The circle graph below shows that 125 people like to travel by train, 275 like to travel airplane and 100 people like to travel by boat.

Therefore, let's use the data to create a pie chart with the measured angles.

Hence,

angle for train travellers = 125 / 500 × 360

angle for train travellers = 45000 / 500

angle for train travellers = 90 degrees

angle for the airplane travellers = 275 / 500 × 360

angle for the airplane travellers =  99000 / 500

angle for the airplane travellers = 198 degrees

Finally,

angle for the boat travellers = 360 - 198 - 90 = 72 degrees.

The slope of the line that passes through the points (2, 8) and (-3, 14) is -6/5 in the simplest form.

A line's steepness may be determined by looking at its slope. Slope is computed mathematically as "rise over run" (change in y divided by change in x).

An ordered pair in mathematics is a set of two things. The order of the objects in the pair matters because, unless a = b, the ordered pair differs from the ordered pair. Ordered pairs are also known as 2-tuples, or 2-length sequences.

The slope of a line is given by the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are two points on the line.

Plugging in the given points, we get:

m = (14 - 8) / (-3 - 2)

m = 6 / -5

m = -6/5

so the slope of the line that passes through the points (2, 8) and (-3, 14) is -6/5 in the simplest form.

The trigonometric function y = sin(3x + π) = 0 for -π/3 ≤ x ≤ π/3.

A trigonometric function is a function that uses one of the trigonometric ratios.

Given that we have the trigonometric function y = sin(3x + π) for -π/3 ≤ x ≤ π/3.

To find the range of output values for the range of input values given, we insert the given values of the input into the equation.

So, for the minimum value of y, we substitute x = -π/3 into the equation.

So, y = sin(3x + π)

y = sin(3(-π/3) + π)

y = sin(-π + π)

y = sin(0)

y = 0

For the maximum value of y, we substitute x = π/3 into the equation.

So, y = sin(3x + π)

y = sin(3(π/3) + π)

y = sin(π + π)

y = sin(2π)

y = sin2π

y = 0

So, y = 0 for -π/3 ≤ x ≤ π/3.

The cottage cheese contains 3.9 g of fat and the apple has 0.13 g, making a total of 4.03 g of fat in the dessert.

Relationships that always have the same ratio are said to be proportional. For instance, the number of trees in an orchard and the number of apples in a harvest of apples are determined by the average number of apples per tree. A linear relationship between two numbers or variables is referred to as proportional in mathematics. When the first quantity doubles, the other number does as well. When one of the variables is reduced to 1/100th of its previous value, the other also decreases. If two quantities are proportional, it means that when one rises, the other rises as well, and the ratio between the two quantities remains constant throughout all values. The diameter and circumference of a circle serve as an example.

given

fat grams from the apple, where a

Since the Top-Notch Middle School had athletes from all the grades playing on a sports team, the ratio 15:73 represents the following: C. The ratio 15:73 represents the ratio of 7th grade football players to total athletes.

In order to interpret and explain the meaning of the given ratio 15:73, we would first of all determine the total number of athletes from all grades in Top-Notch Middle School as follows;

Total number of athletes, T = 2 + 4 + 7 + 1 + 6 + 5 + 7 + 4 + 4 + 8 + 15 + 10

Total number of athletes, T = 73 athletes.

For the number of Basketball athletes, we have:

Number of Basketball athletes, B = 2 + 4 + 7

Number of Basketball athletes, B = 13 Basketball athletes.

Ratio of B to T = 13:73.

For the number of Baseball athletes, we have:

Number of Baseball athletes, B = 1 + 6 + 5

Number of Baseball athletes, B = 12 Baseball athletes.

Ratio of Ba to T = 12:73.

Side a of the oblique triangle is 25.57 units and side b is 9.42 units.

The number of sides of a triangle and how their individual sine angles are equal are determined by the law of sines. Other names for the sine law are sine rule, sine formula, and sine law. The law of sine is used to determine the side or unknown angle of an oblique triangle.

Given:

∠A = 107

∠B = 21

∠C = 52

c = 21

So, using the law of sines

b/sin B = c/ sin C

b/sin 21 = 21/sin 52

b = (21 × sin 21) / sin 52

= (21 × 0.35) / (0.78)

b ≈ 9.42

Similarly, side a of the triangle is given by

a/ sin A = c/ sin C

a/sin 107 = 21/sin 52

a = (21 × sin 107) / sin 52

= (21 × 0.955) / (0.78)
