Cartographers use trigonometry for topographic mapping, while navigators use it to direct navigation, helping to identify location and distance.

Surveyors, on the other hand, use trigonometry to measure spatial data, such as height and angles of the land and urban and rural georeferencing.

Trigonometry studies the relationships between the sides and angles of a triangle. This calculation instrument is used for studies in various fields of scientific knowledge, such as the study of phenomena in mechanics, engineering and medicine.

Therefore, there are several applications for trigonometry in social daily life, being an instrument that helps in obtaining scientific knowledge and development of society.

Answer:

This was my answer, I did a lot of research for it

Step-by-step explanation:

According to wonderworksonline.com, "cartographers use the laws of plane trigonometry". This is used for topographical mapping which is a map that includes detailed, accurate landmarks.

Navigators use trigonometry to find directions. According to byjus.com, "with the help of a compass and trigonometric functions in navigation, it will be easy to pinpoint a location and also to find distance as well to see the horizon."

Trigonometry is used in land surveying to measure to height and angles of the land. According to prezi.com, "it can be used to measure the elevation from a certain point to a mountain, the distance between two trees, and distances across lakes."

Another profession that uses trigonometry is astronomy. Trigonometry is used to measure the distance between stars and planets. According to mytutor.co.uk, "this mathematical technique is also used by NASA scientists today when they design and launch space shuttles and rockets."

Trigonometry plays an important part in our everday lives. Without trigonometry, we wouldn't have GPS to navigate us. Trigonometry is also used by flight engineers to decide take off paths. Trigonometry is also used in the medical field for ultrasounds, the process of building prosthetic legs and arms, and surgeries.

Step-by-step explanation:

An equation is formed of two equal expressions. The cost of a new book is $7.43, while the cost of an old book is $8.86.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the cost of 14 used books is $124. Therefore, the cost of a single used book is,

Cost of single used book(u) = 124/14 = $8.86

Also, the cost of 12 used books and 4 new books is $136. Therefore, the equation can be written as,

12u + 4n = 136

12(8.85) + 4n = 136

106.2 + 4n = 136

n = $7.43

Hence, the cost of a new book is $7.43, while the cost of an old book is $8.86.

Hey there!

The area of a shape is the total measurement of the inside of the shape

Meaning the parts I shaded in the screenshot

As you can see in the image, there is less area in shape B than shape A

Meaning, that the area has decreased

Now, Tom says that both area and perimeter has decreased

Lets check if the perimeter has decreased

If you look at it, the perimeter hasn't decreased at all

All that has happened was the shape getting a new form

The dimension are basically split

For example, if the top side of the square was 6 inches

Then the dimension after taking out a square from the shape would split

The top side of that square after is was split would be something along the ligns of 4 inches, and 2 inches and other dimensions like that

That is how I think of the perimeter and if it changes or not

But this explains why Tom is wrong

Since the perimeter is still the same

Using proportions, it is found that the family will drive 482.8 km on the new route.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:

D = 1.25 x 240 = 300 miles.

Since there are are approximately 48.28 kilometers in 30 miles, and 300/30 = 10, the distance in kilometers is given by:

D = 48.28 x 10 = 482.8 km.

A Venn diagram is used to visually represent the differences and the similarities between two concepts.

Total students= 900

students like tea=600

students like coffee=500

Students did not like both drinks=125

Students who both or any one of the drinks= 900-125=725

Now,

students like both drinks= 600+500-725

Answer:

Step-by-step explanation:

11m + 7m is 18m
The final answer is 18m

The change in altitude of the kingfisher is 18 m.

The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex.

Suppose the distance above the cliff is represented by a positive integer.

Then the distance below it is represented by a negative integer.

Thus, change in altitude of the kingfisher

= 7-(-11)

= 7+11

= 18 m

Hence, the change in altitude of the kingfisher is 18 m.

Answer:

Answer:

the 4th option because 24 months times the amount plus the 39.99 to set up would get you a final answer

Answer:

39.99/24c = 351.75

24c + 39.99 = 351.75

Where c is the cost to set up an account

Step-by-step explanation:

Knowing that it given:

What is the cost(c) month for using the service for 24 months?

That means "Cost = c"

That leads us to the answer:

"Where c is the cost to set up an account"

We also know that we are finding for the 24 months thus 24c.

That leads us to

24c + 39.99 = 351.75 and 39.99/24c = 351.75

Hence, the answers are:

39.99/24c = 351.75

24c + 39.99 = 351.75

Where c is the cost to set up an account

Kavinsky

Answer:

2sin((1)x + 135)-3

Step-by-step explanation:

Asin(Bx+C)+D

A = amplitude = distance from top to bottom divided by 2

y value of top = -1

y value of bottom = -5

distance from top to bottom = -1 - (-5) = 4

divide by 2 to get 4/2 = 2 as our amplitude

2π/B = period

in this case, we're working in degrees for our x axis - 2π = 360°

thus, 360°/B = period

period = time it takes to get from one high to the next (alternatively, one low to the next etc.) = 360 degrees in this case

thus, 360°/B = 360°

divide both sides by 360° and multiply both sides by B to isolate B

360/360 = B = 1

phase shift = -C/B

phase shift refers to how much the graph is shifted to the left/right. normally, the middle of a sin wave is at 0, with a peak being to the right of it. now, the middle of the sin wave (which has a peak to the right of it) is at x = -135 degrees to the right of a regular sine wave

thus,

-135 degrees = -C/B

B = 1

-135 degrees = -C

C = 135 degrees

D = vertical shift

the center is now at y = -3. normally, the center is at y = 0. thus, D = -3

our formula is thus

2sin((1)x + 135)-3

The average speed of Keane’s journey in mph is 56.25 mph (miles per hour)

From the question, we are to determine Keane's average speed

Average speed is given by the formula,

Average speed = Distance / Time

Distance travelled = 180 miles

Now, we will calculate the time spent

From the given information,

He leaves his home at 09:30 and arrives in Liverpool at 12:42

09:30 to 12:42 is 3 hours 12 minutes

∴ Time = 3 hours 12 minutes = 3 + (12/60) hours = 3.2 hours

Thus,

Average speed = 180 / 3.2

Average speed =  56.25 mph (miles per hour)

Hence, the average speed of Keane’s journey in mph is 56.25 mph (miles per hour)
