Choose the three true statements about the angles in the figure.

On solving the query we can say that The slant height, along with the function cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

Mathematics is concerned with numbers and their variations, equations and related structures, shapes and their places, and possible placements for them. The relationship between a collection of inputs, each of which has an associated output, is referred to as a "function". An relationship between inputs and outputs, where each input yields a single, distinct output, is called a function. Each function has a domain and a codomain, often known as a scope. The letter f is frequently used to represent functions (x). X is the input. The four main types of functions that are offered are on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

You are informed that the cone in this scenario has a volume of 4.5 cubic inches. Using the aforementioned calculation, you can determine the radius if you know the cone's height.

Alternately, you may use the Pythagorean theorem to calculate for the radius if you know the cone's slant height. The slant height, along with the cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

Answer:

The original price of the shirt was Ksh 500 and it was sold for Ksh 550.

The discount is the difference between the original price and the selling price, which is Ksh 500 - Ksh 550 = Ksh -50.

To find the percentage discount, we can use the formula:

percentage discount = (discount ÷ original price) × 100%

percentage discount = (-50 ÷ 500) × 100%

percentage discount = -10%

Therefore, the percentage discount is 10%.

The figure labelled JKLM is a kite and the length ML is equal to 11.

A kite is a quadrilateral that have two pairs of equal length of sides and these sides are adjacent to each other. It can be viewed as a pair of congruent triangles with a common base.

The line JM bisects the kite into two congruent triangles, and thus;

the lengths ML and MK are equal.

ML = 5x - 4 and MK = 2x + 5 so;

5x - 4 = 2x + 5 {collect like terms}

5x - 2x = 5 + 4

3x = 9

x = 9/3 {divide through by 3}

x = 3

we substitute 3 for x;

ML = 5(3) - 4

ML = 15 - 4

ML = 11

A surveyor plays a crucial role in land surveying and mapping, using various tools and techniques to accurately measure and analyze land features.

Trigonometric functions are fundamental mathematical tools that surveyors rely on to solve problems involving angles, distances, and elevations. By employing trigonometry, surveyors can determine the precise locations of points, measure distances between objects, and calculate elevations with accuracy and efficiency. This essay will explore how surveyors utilize trigonometric functions in their work, highlighting key vocabulary words and providing three detailed examples.

One of the primary applications of trigonometry in surveying is angle measurement. Surveyors use the concept of trigonometric ratios, such as sine, cosine, and tangent, to determine angles between reference points. By measuring the lengths of sides in a triangle formed by the surveyor's position and the target point, trigonometric functions enable them to calculate the unknown angles. For instance, when surveying a land boundary, a surveyor may use the tangent function to determine the angle of deflection between two adjacent lines, helping establish accurate boundary lines.

Another crucial application of trigonometry in surveying is distance measurement. By utilizing trigonometric principles, surveyors can measure distances that are difficult or impractical to physically traverse. For instance, when faced with measuring the width of a river or the height of a tall structure, a surveyor can employ trigonometry along with the concept of similar triangles. By measuring the angles of elevation or depression from the surveyor's position to the target point and knowing the distance between two reference points, they can calculate the unknown distance using trigonometric functions like sine or tangent.

Elevation determination is yet another area where surveyors rely on trigonometric functions. By combining angle measurements and distance measurements, surveyors can determine the elevation of a specific point above a reference level. For example, when conducting a topographic survey to create a contour map, surveyors measure the angles of elevation or depression to various points on the terrain. By applying trigonometry, they can calculate the differences in elevations between these points and establish contour lines representing the shape and relief of the land.

In conclusion, trigonometric functions are indispensable tools for surveyors in their day-to-day work. Angle measurement, distance measurement, and elevation determination are just a few examples of how surveyors employ trigonometry to accomplish accurate and precise land surveying. By understanding trigonometric concepts and utilizing key vocabulary words such as sine, cosine, tangent, angles of deflection, and angles of elevation, surveyors can confidently carry out their tasks, ensuring reliable measurements and mapping of land features. Trigonometry empowers surveyors to overcome challenges in measuring angles, distances, and elevations, contributing to the accurate representation of the physical world and supporting various engineering and construction projects.

Given the number of trees in the orchard, the number of trees in each row is 20 trees.

Assuming that the number of rows is represented as x, the number of trees would be 2 less than the number of rows which makes it:

= x - 2

The number of trees is:

x ( x - 2) = 440

x² - 2x - 440 = 0

Solving for r can then be done quadratically which gives us:
x = (2 ± √(2² - 4(1) (- 440)) / 2 (1)

= 22, and -20

The number of rows in the orchard cannot be negative so the number of rows is 22.

Answer:

8 pigs

Step-by-step explanation:

Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.

Suppose all animals are chickens.

Total no. of feet = 26 chickens × 2 feet

                           = 52 feet

Difference in total no. of feet = 68 feet - 52 feet

                                                = 16 feet

Difference in no. of feet each animal has

= 4 feet (a pig) - 2 feet (a chicken)

= 2 feet

∴ No. of pigs = 16 feet ÷ 2 feet

                      = 8 pigs

The next 3 terms of the sequence defined recursively by the formula f(n + 1) = f(n) + 2 are; 1, 3 and 5.

A sequence is defined as an arrangement of numbers in a particular order.

From the question f(n + 1) = f(n) + 2 such that rewriting we have;

f(n) = f(n + 1) - 2

The first is -1, so n = 1 and we derive the next term f(2) as follows;

f(1) = f(1 + 1) - 2 = -1

f(1) = f(2) - 2 = -1

f(2) = 2 - 1 {add 2 to both sides}

f(2) = 1

f(2) = f(2 + 1) - 2 = 1

f(3) = 2 + 1 {add 2 to both sides}

f(3) = 3

f(3) = f(3 + 1) - 2 = 3

f(4) = 3 + 2 {add 2 to both sides}

f(4) = 5

Therefore, we have the next three terms of the sequence to be 1, 3, and 5.

The position of the image is 42.25 cm in front of the lens. and its height is 5.64 cm and inverted.

We can use the thin lens equation to find the position of the image:

\(1/f = 1/d_o + 1/d_i\)

where f is the focal length of the lens, \(d_o\) is the object distance (distance between object and lens), and \(d_i\) is the image distance (distance between image and lens). We can solve for \(d_i\):

\(1/d_i = 1/f - 1/d_o\)

f = R/2 for a plano-convex lens with radius of curvature R, so in this case

\(f = 13 cm/2 = 6.5 cm\).

Plugging in \(d_o\) = 15 cm and f = 6.5 cm, we get:

\(1/d_i = 1/6.5 - 1/15\\1/d_i = 0.1538\\d_i = 6.5/0.1538\\d_i = 42.25 cm\)

So the position of the image is 42.25 cm in front of the lens.

To find the height of the image, we can use the magnification equation:

\(m = -d_i/d_o\)

where m is the magnification (negative for a virtual image), \(d_i\) is the image distance (which we just found), and \(d_o\) is the object distance (given as 15 cm).

\(m = -42.25/15\\m = -2.82\)

This means that the image is 2.82 times smaller than the object. Since the object is 2.0 cm tall, the height of the image is:

\(h_i = mh_o\\h_i = -2.822.0 cm\\h_i = -5.64 cm\)

The negative sign indicates that the image is inverted (upside down). So the position of the image is 42.25 cm in front of the lens, and its height is 5.64 cm and inverted.
