A ship travels 200 km west from port and then 240 km due south before it is disabled. Illustrate this in a vector diagram. Use trigonometry to find the course that a rescue ship must take from port in order to reach the disabled ship.
The course that a rescue ship must take from port in order to reach the disabled ship is 312.4 km at a direction of 50.2⁰.
Sketch of the ship's motionThe sketch of the journey of the ship can be used to determine the course that a rescue ship must take from port in order to reach the disabled ship.

Displacement of the shipThe displacement of the ship from the initial position is calculated as follows;
d² = 200² + 240²
d² = 97,600
d = √97,600

Answer:
48 drops
Step-by-step explanation:
you see that for every 8 drops of yellow there's 12 drops of red and there ends up being 32 drops of yellow and 32/8=4 so you take 12x4 to get how many drops of red.
The perimeter of the base of a right square pyramid is 24 cm. The height of the pyramid is 6 cm. What is the volume of the pyramid? 48 cm3 72 cm3 32 cm3 60 cm3
Answer:
72cm
Step-by-step explanation:
The volume of the base of a right square pyramid is 72 cubic centimeters, the option second is correct.
It is given that the perimeter of the base of a right square pyramid is 24 cm and the height of the pyramid is 6 cm.
It is required to find the volume of the right square pyramid.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We know the formula for finding the volume (V) of a right square pyramid is:
[tex]\rm V= a^2\times\frac{h}{3}[/tex] Where a is the base side and h is the height of the right square pyramid.
[tex]\rm The \ perimeter \ of \ the \ base \ of \ a \right \ square \ pyramid = 4\times(side)[/tex]
[tex]\rm 24 = 4a\\\rm a=6 \ cm[/tex]
And h = 6 cm, putting this value in the above volume formula, wet get:
[tex]\rm V= (6)^2\times\frac{6}{3} \\\rm V= 36\times 2\\\rm V=72 \ cm^3[/tex]
Thus, the volume of the base of a right square pyramid is 72 cubic centimeters, the option second is correct.

choose the best selection for the quadrilateral with vertices at following points
0,0 -2,3 7,0 5,3
Answer:
The quadrilateral has two pairs of opposite parallel sides and (from the graphing of the points) it is slanted from the vertical, therefore, it is a;
B. Parallelogram
Step-by-step explanation:
The coordinates of the vertices of the given quadrilateral are;
(0, 0), (-2, 3), (7, 0), (5, 3)
Arranging the coordinates according to their y-values and labelled gives;
A(-2, 3), B(5, 3), C(0, 0), D(7, 0)
The graph of the points created with Microsoft Word and Microsoft Excel is attached
From the graph, we have;
Segment AB is parallel to segment CD
The length of segment AB = √((5 - (-2))² + (3 - 3)²) = 7
The length of segment CD = √((7 - 0)² + (0 - 0)²) = 7
∴ The length of segment AB = The length of segment CD
The distance between segment AC and segment BD = Length of segment AB at point A = Length of segment CD at point C
∴ Segment AC is parallel to segment BD (The distance between two parallel lines is the same all through)
The quadrilateral is also observed to be slant from the vertical
Therefore the quadrilateral is a parallelogram

Answer:
Maximum = 61.1
Step-by-step explanation:
Given - Here are the percents of the popular vote won by each successful candidate in 15 presidential elections. 49.6, 55.1, 57.4, 49.7, 61.1, 43.4, 60.7, 50.1, 50.7, 58.8, 53.9, 43.2, 49.2, 47.9, 51.2
To find - What is the maximum ?
Proof -
We have to find which candidate got highest votes in the election .
For this, we first arrange all 15 in ascending order i.e. lowest to highest.
Now,
The arrangement is like this -
43.2,
43.4,
47.9,
49.2,
49.6,
49.7
50.1,
50.7,
51.2,
53.9,
55.1,
57.4,
58.8,
60.7,
61.1
From this , we get
Lowest votes = 43.2
Highest votes = 61.1
⇒Maximum = 61.1

Given g(x)=-x-2g(x)=−x−2, find g(0)g(0).
Answer:
g(0) = -2
Step-by-step explanation:
Given - g(x) = -x - 2
To find - g(0)
Proof -
We have given the function ,
g(x) = -x - 2
For finding the value of g(0), we just have to put x = 0 in g(x),
We get
g(0) = -0 - 2 = -2
⇒g(0) = -2
Which equation represents a line that is parallel to the line represented by
4x + y = 7 and passes through the point (1, 8)?
Answer:
y = -4x + 12
Step-by-step explanation:
For a line to be parallel, it needs to have the same slope.
Point intercept form: y - y₁ = m (x - x₁)
Where y and x are just kept as y and x, y₁ and x₁ are the parts of a coordinate, and m = slope.
So, in order for the line to be parallel, it needs to have the same slope as the first equation. The slope of the line (which is the "m" in y = mx + b) is..
4x + y = 7
y = -4x + 7
So, m, or the slope, is -4.
Plug this, along with the coordinate the problem gives you into point-intercept form.
y - y₁ = m (x - x₁)
y - 8 = -4 (x - 1)
Simplify.
y - 8 = -4x + 4
Add 8 to both sides.
y = -4x + 12
