Solve a ship leave port and travel 21km on a bearing of 032° and then 45km on a bearing 287 calculate the distance and bearing of the port from the ship
Answer:
Step-by-step explanation:
Let shall be considering the Cosine rule in this situation.
a^2 = b^2+c^2- 2bc.cosA
Where a = ?
b = 21km
c 45km
A = 131
a^2 = 21^2+45^2-2(21*45).cos131
a^2 = 441+2025-1890(-0.6560)
a^2 = 2466+1239.951
a^2 = 3705.951
a= 60.876km
Finding the bearing of the port from the ship.
We shall be considering the Sine rule
Sin A/a = Sin B/b
Where A = ?
a = 45km
B = 131°
b = 60.876km
Sin A/45 = sin131/60.876
SinA×60.876 = 45×sin131
SinA×60.876= 45×0.7547
SinA×60.876 = 33.961
SinA= 33.961/60.876
SinA = 0.5578
A = sin^-1 0.5578
A = 33.9°

PLEASE HELP ASAP! WILL GIVE BRAINLIEST! The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answer:
Solution:- In the given figure
Side of square= 10 cm
area of square = side x side m= 10 x 10 = 100 sq cm
Now , diameter of semi circle AOD = 2r = 10cm
⇒ radius of semi circle AOD = 5 cm
∴ area of AOD =
similarly Area of semicircle BOC =
Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]
=
Total area of white portion in the given figure=
∴Area of Shaded portion = area of square - area of total white portion
=
So the area of shaded portion is
Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)
So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm

Observa las siguientes imágenes formadas por círculos:
Figura 1 (un circulo) Figura 2 (5 círculos)
-¿Cuántos círculos tendrá la Imagen 10?
-¿Cuántos círculos más tendrá la imagen 12 respecto de la imagen 7? ¿Puedes saberlo sin necesidad de encontrar la cantidad de círculos de cada imagen? ¿Cómo?
Veremos que en la imagen 10 hay 37 circulos, y la diferencia entre las imagenes 12 y 7 es de 20 circulos.
¿Como encontrar el patrón?
Primero, debemos contar la cantidad de circulos que tenemos en las imagenes mostradas.
En la primera, tenemos 1 circulo.En la segunda, hay 5 circulos.En la tercera, hay 9 circulos.En la cuarta, hay 13 circulos.Entonces podemos ver que en cada imagen se agregan 4 circulos, es decir tenemos una secuencia aritmetica, de tal forma que la imagen número N tendremos:
[tex]C_N = 1 + (N - 1)*4[/tex]
Entonces, cuantos circulos hay en la imagen 10? para ver eso reemplazamos N por 10.
[tex]C_{10} = 1 + (10 - 1)*4 = 37[/tex]
¿Cuántos círculos más tendrá la imagen 12 respecto de la imagen 7?
Para ver esto calculamos:
[tex]C_12 - C_7 = (1 + (12 - 1)*4) - (1 + (7 - 1)*4) = 11*4 - 6*4 = 20[/tex]
Es decir, la image 12 tiene 20 circulos más que la imagen 7.

firstly u can take the value of x=3 then put the value of x in equation..then u will get y = 0 so from this equation u get this(3,0)
then do same thing take value x = 6 and then u will get the value of y = -1 therefore u will get (6,-1)
Now plot these two points (3,0) and (6,-1) on graph..

Two quantities of data have a strong positive correlation. Can the line of best fit for the data set have a correlation coefficient of 0.25? Explain.
Choose the correct answer below.
O A. Yes. The sign of the correlation coefficient indicates the type of correlation data have. Because 0.25 is positive, it is possible for data with a strong
positive correlation to have it as the correlation coefficient
OB. No. By definition, data that have a strong positive correlation have a strong linear relationship. The correlation coefficient would be closer to 1 than 0.25 is
OC. No. By definition, data that have a strong positive correlation have a strong linear relationship. The correlation coefficient would be closer to - 1 than 0.25
OD. No. By definition, data that have a strong positive correlation have a strong linear relationship. The correlation coefficient would be closer to than 0.25 is.
O E. Yes. By definition, data that have a strong positive correlation have a strong linear relationship. A correlation coefficient of 0.25 indicates a fairly strong

What is the remainder in the synthetic division problem below?
1|4 6 -3
A. 3
B. 7
C. 5
D. 9
The correct option is (b) i.e. In the given synthetic division, the remainder will be 7.
What is Remainder ?
The remainder is what "remains" after an activity is finished, as its name implies. In mathematics, it is impossible to divide 17 by 3 precisely. The leftover after division is the number 2, which is set aside.
Given : 1 | 4 6 -3
If we solve it further, we get
1 | 4 6 -3
| 4 10
| 4 10 7
Steps :
firstly we will write 4 as it is .
we will multiply 1 by 4 and write it in the second place, then we will add 6 and 4.
Similarly, we will multiply 1 by 10 and write it in the third place, then we will add -3 and 10 and finally get 7 as residual.
here, after solving, we get 7 in the end which is set aside.
So, the remainder will be 7.
Hence, the correct option is (b).

[tex]\frac{4}{3}\pi r^{3}[/tex]
that is the formula, with r being the radius.
then if you replace r with 7 that would be the answer.
pi, also equals 3.14159265359, or shortened 3.14.
so it would look like:

The points with coordinates (0, 3) and (8, 5) lie on the straight line L. Write down an equation of L.
Answer:
y = (1/4)*x + 3
Step-by-step explanation:
A linear equation can be written as:
y = a*x + b
Where a is the slope, and b is the y-intercept.
If the line passes through the points (x₁, y₁) and (x₂, y₂) the slope can be written as:
a = (y₂ - y₁)/(x₂ - x₁)
In this case, we know that the line passes through the points (0, 3) and (8, 5)
Then the slope will be:
a = (5 - 3)/(8 - 0) = 2/8 = 1/4
Then this line is something like:
y = (1/4)*x + b
Now we want to find the value of b.
Here we can use one of the two points that we know, for example, I will use the point (0, 3), this means that when x = 0, we must have y = 3.
If we replace those two values in the line equation, we get:
3 = (1/4)*0 + b
3 = b
Then the equation for the line L is:
y = (1/4)*x + 3

Answer:
The answer is 2
Step-by-step explanation:
First you need to calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. All of the points add up to 10. Then you divide that number by how many points there are which is 5 and you get 2.
