first person to correctly answer will get brainliest
Answer:
A = 20% B = 36%
Step-by-step explanation:

This past winter, 643 flamingos migrated to Gordon Lake. A researcher states that the number of flamingos migrating to the lake is decreasing by 12 birds every year. Which of the following represents the number of flamingos, n, that will migrate to the lake t winters from last winter if the researcher’s trend continues? A. t = 643 - 12n B. n = 643 - 12t C. t = 12 - 643n D. n = 12 - 643t
Answer:
n=643-12t

B) The angle of depression from an observation tower to boat A is 28 degrees. The angle of depression from the same point of the tower to boat B is 45 degrees. If the tower is 60 meters tall, approximately how far is boat A from boat B.
Answer:
53 meters
Step-by-step explanation:
The angle between a viewer's horizontal line of sight and the line of sight down towards a particle is called the angle of depression. For example if a viewer is sitting at the top of a tower and looking down on a car, the angle between the viewer's horizontal line of sight and the line of sight to which he looks at the car is the angle of depression.
A sketch of the positions of the boats and the tower has been attached to this response.
As shown,
the distance between the two boats A and B is marked x meters.
the horizontal distance between boat A and the foot of the tower is y meters.
the horizontal distance between boat A and the foot of the tower is x + y meters.
the height of the tower is 60 meters.
the angle of depression of boat A is 28°
the angle of depression of boat B is 45°
To find the value of y, from triangle DBC we use the trigonometric ratio for tangent. i.e
tan 45° = [tex]\frac{60}{y}[/tex]
1 = [tex]\frac{60}{y}[/tex]
y = 60 meters
To find the value of x, from triangle ABC we use the trigonometric ratio for tangent. i.e
tan 28° = [tex]\frac{60}{x+y}[/tex]
Where y = 60 meters
tan 28° = [tex]\frac{60}{x+60}[/tex]
0.5317 = [tex]\frac{60}{x+60}[/tex]
x + 60 = [tex]\frac{60}{0.5317}[/tex]
x + 60 = 112.85
x = 112.85 - 60
x = 52.85 meters
Therefore, boat A is about 53 meters from boat B

Find the first 6 terms of the sequence.
Step-by-step explanation:
you really need help with that ? it is all already given in the problem description. you only need to do the 6 little calculations (anyways adding 6). what is the problem ?
a1 = 7
a2 = a1 + 6 = well ? ... ... ... 13, of course
a3 = a2 + 6 = 13 + 6 = weeeeelllll ?
a4 = a3 + 6 = 13 + 6 + 6 = weeeellll ?
a5 = a4 + 6 = 13 + 6 + 6 + 6 =
a6 = a5 + 6 = 13 + 6 + 6 + 6 + 6 =
I am really not doing your very basic and just "mechanical" work of doing simple calculations in your head or on your calculator.
I help you, when you have a problem understanding the issue, but not when you ask me to do your pure "mechanical" job that every elementary school student can do easily.
to help with the understanding, such a sequence (using this example) can then be described and every element calculated by
a(n) = a(1) + 6*(n-1)
so, for example
a20 = 7 + 6*19 = 121
so, and now that you truly understand the concept, just use your calculator (if you truly cannot do that in your head) and do your job.

Are these events independent or dependent?
A. Picking two colored pencils out of a box.
B. Picking a number from a hat, putting it back and choosing a second number.
Answer:
B is dependent and A is independent
Step-by-step explanation:
dependent events depend on the outcome or occurrence of the first one. independent is the opposite. it doesn’t have an effect on another event occurring.
it can be kind of confusing but I hope this helped :)
Which expression has twice the value of 2 times 2 times 2 times 2 times 2?
2 Superscript 6
2 Superscript 10
4 Superscript 5
4 Superscript 10
Answer:
2 To the 6'th power.
Step-by-step explanation:
2x2x2x2x2=32
twice the value of 32 is 64
2x2x2x2x2x2=64
so your answer would be 2 to the sixth power

Select the correct answer. Which equation represents circle Q? A. (x − 11)2 + (y − 3)2 = 241 B. (x − 11)2 + (y − 3)2 = 209 C. (x + 11)2 + (y + 3)2 = 241 D. (x + 11)2 + (y + 3)2 = 209
Answer:
(x+11)² + (y-3)² = 121
Step-by-step explanation:
Let us assume we are given the following
Centre of a circle: (-11, 3)
Radius: 11
The standard equation of a circle is expressed as;
(x-a)² + (y-b)² = r²
(a, b) is the centre
r is the radius
a = -11, b = 3 and r = 11
Substitute
(x-(-11))² + (y-3)² = 11²
(x+11)² + (y-3)² = 121
Hence the required equation of the circle is (x+11)² + (y-3)² = 121
Note that the centre and the radius of the circle was assumed
