Mediante la ley del seno, la longitud del faro es aproximadamente igual a 8.295 metros.
¿Cómo determinar la longitud del faro mediante leyes trigonométricas?
En esta pregunta nos encontramos con una sistema geométrico con dos ángulos y un lado conocidos, la configuración permite determinar la altura del faro mediante la ley del seno, cuya expresión sería la siguiente:
AC / sin B = AB / sin C = BC / sin A
Donde BC es la longitud del faro, medida en metros, y AC es la distancia horizontal hasta la base del faro, medida en metros. Si sabemos que AC = 9.9 m, B = 53° and A = 42°, entonces la longitud del faro es:
(9.9 m) / sin 53° = BC / sin 42°
BC = 9.9 m × (sin 42° / sin 53°)
BC ≈ 8.295 m

1) Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.
2) The total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.
3) Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.
4) Total distance from Mercury to Earth is 56,700,000 miles.
5) Venus is 22,300,000 miles closer to Earth than Mars.
6) Earth is 745,000,000 miles farther from Mars than Saturn.
Given,
1) Distance from Earth to Saturn = 793,000,000 miles
Distance from Earth to Jupiter = 390,400,000 miles
793,000,000 - 390,400,000 = 403,400,000
That is, Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.
2) Distance from Saturn to Jupiter = 403,400,000 miles
Distance from Jupiter to Mars = 342,000,000 miles
403,400,000 + 342,000,000 = 745,400,000
Therefore, the total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.
3) Distance from Saturn to Jupiter = 403,400,000 miles
Distance from Saturn to Earth = 793,800,000 miles

So, Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.
4) Distance from Mercury to Venus = 30,700,000 miles
Distance from Venus to Earth = 26,000,000 miles
30,700,000 + 26,000,000 = 56,700,000
That is, the total distance from Mercury to Earth is 56,700,000 miles.
5) Distance from Earth to Venus = 26,000,000 miles
Distance from Earth to Mars = 48,300,000 miles
48,300,000 - 26,000,000 = 22,300,000
That is, Venus is 22,300,000 miles closer to Earth than Mars.
6) Distance from Earth to Saturn = 793,800,000 miles
Distance from Earth to Mars = 48,300,000 miles
793,800,000 - 48,300,000 = 745,500,000
That is, Earth is 745,000,000 miles farther from Mars than Saturn.

how to translate by the rule (x,y)->(x +6,y -3) then reflect image over the y axis
Transformation of Reflect image over the y axis for this equation (x ,y)->(x +6,y -3) is (3, -1)
Reflecting point (-6,1) on y = x
gives (1, -6)
Translating, (1, -6) by 2,5 is
(1 + 2, - 6 + 5) = (3, - 1)
Therefore, reflect image over the y axis translate by rule (x ,y)->(x +6,y -3) is (3, - 1)
transformation :A function, f, itself is called the transformation, i.e., f: X → X. After the transformation the pre-image X becomes the image X. This transformation can be any part or the mixture of operations such as translation, reflection, rotation and dilation. The translation is working a function in a particular direction, rotation is rotate the function to a point, reflection is the mirror image of the function, and dilation is the ascend of a function.
Translation, rotation, reflection, and dilation are the four most prevalent types of transformations. From the transformation, we have a rotation about any point, reflection over any line, and translation along any angle. The picture is congruent to its pre-image in these stiff transformations.. They are also called as isometric transformations. Dilation is performed at about any point of angle and it is non-isometric.
Rules for Transformations
Consider a function f(x). On a coordinate grid, we use the x-axis and y-axis to check the movement. Here are the rules for transformations of function that could be applied to the all graphs of functions. Transformations can be shown algebraically and graphically. Transformations are commonly found in algebraic functions. We can use the formula of transformations in graphical functions to obtain the graph just by transforming the fundamental or the parent function, and thereby move the graph around, rather than tabulating the coordinate values. We can visualize and learn algebraic equations with the aid of transformations.
Formula of Transformations
Let us consider the graph f(x) = [tex]x^{2}[/tex]
Suppose we have need to graph f(x) = [tex]x^{2}[/tex] -3, we shift the vertex 3 units down.
Suppose we have need to graph f(x) = 3 [tex]x^{2}[/tex]+ 2, we shift the vertex two units above and extend vertically by 3 factor
Suppose we have need to graph f(x) = 2(x-1)^2, we shift the vertex one unit to the right and extend vertically by 2 factor
Thus, we know the formula of transformations as
f(x) =a(bx-h) n + k
where k is the vertical shift,
h is the horizontal shift,
a is the vertical stretch and
b is the horizontal stretch

Enter
The circumference of the circle with radius 7 and value of pie 3, using the formula C= 2pie r is 42 unit.
Circumference of this circle using 3 for TT and 7 as radius.
The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference. There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.
Circumference of circle = π x Diameter of circle.
You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.
Here, π = 3, r = 7,
So C = 2*7*3 = 42 units.

The amount of the total rent is 120 dollars.
How to find the total rent using average?Four students plan to rent a minivan for the weekend and equally share the rental cost.
By adding one more people, they can each save $6.
Therefore, the 4 students equally share the rent.
Hence,
average for 4 student = total amount shared / number of student
average for 4 student = x / 4
When you add one more person,
average for 5 student = x / 5
Therefore, the difference, will give you the total amount of the rent.
x / 4 - x / 5 = 6
5x - 4x/ 20 = 6
x / 20 = 6

A bee flies at 12 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 14 minutes, and then flies directly back to the hive at 8 feet per second. It is away from the hive for a total of 19 minutes.
The distance, D, is 5,760,000 divided by 2,160, which is 2666.67 (approx)
What exactly does "time function" mean?The TIME function is included as part of Excel's Date and Time features. With the assistance of TIME, we are able to create a time by employing various components for the hours, minutes, and seconds.
While conducting financial analysis, it's possible that we'll need to date a report. Under these conditions, the TIME function may be used to convert a text string into a format that presents the time as a decimal representation of the seconds, minutes, and hours.
Additionally, the function's capabilities include the ability to merge several values into a single time value.
formula= TIME (hour, minute, second)
distance = rate X time
D = RT
T = D/R
720 feet in a minute is equal to 12 feet per second.
480 feet per minute is equal to 8 feet per second.
The number of minutes to go to the flowerbed plus 14 minutes plus the number of minutes to get back to the hive equals 19 minutes.
(D/R) + 14 + (D/R) = 19
(D/R) + 14 + (D/R) = 19
In conclusion, The calculation that we may use to get the distance from the flowerbed to the hive is (D/720 ) plus 14 plus (D/480), which is 19.
(D/720 ) + (D/480) = 5
(D(1200)(480))/1200 + (D(720 )(480))/960 = 5(1200)960
480D + 1200D = 5(720 )480
