4. A plane at an altitude of 10,000 feet is approaching an island. At a given moment, the angle of depression to the near side of the island is 56° and the angle of depression to the far side of the island is 24º. Determine the length of the island, in miles, as seen in the figure below. (8 points) Show all of your work, using correct mathematical notation, on a different piece of paper Answer the question in a complete sentence. Clearly define all of your variables. You may define your variables by labeling the picture or drawing appropriately. The abbreviations opp, adj, and hyp may not be used as variables.
Answer:
The angle of depression calculator. How to find the angle of depression?
Since we now know what the angle of depression is, let's learn how to find it! We can determine the angle of depression using surveying equipment like an engineer's transit or a clinometer. These devices are optical instruments that have angle-measurement features and can instantly give us the angle that we need. However, we can also use mathematics to find the angle of depression. But first, we need to know two distances: the horizontal distance between the viewer and the object, and their vertical distance, as shown in the illustration below:
Express the product of 300 and 500 in scientific notation.
Answer:
It should be [tex]15*10^{4}[/tex].
Step-by-step explanation:
[tex]300=3*10^{2}\\500=5*10^{2}\\\\300*500=(3*10^{2})*(5*10^{2})=(3*5)*10^{(2+2)}=15*10^{4}=1.5*10^{5}[/tex]
Answer: 1.5 x 10^5
Step-by-step explanation:
The first step is to re-arrange the factors like this :
5 x 3 x 10^2 x 10^2
Since
5 x 3 = 15
and the index law
10^a x 10^b = 10^a + ^b
gives us
10^2 x 10^2 = 10^2 + ^2 = 10^4
then we can rewrite the product like this :
5 x 3 x 10^2 x 10^2 = 15 x 10^4
Finally, we need to convert this into scientific notation :
15 x 10^4 = 1.5 x 10^5
So the final answer is
1.5 x 10^5

From which set of dimensions could a triangle be constructed?
side length of 7
side length of 8
side length of 15
side length of 8
side length of 5
side length of 14
side length of 6
side length of 3
side length of 10
side length of 2
side length of 6
side length of 7
Answer:
side length of 2
side length of 6
side length of 7
Step-by-step explanation:
So remember the two shorter lengths added together have to be greater than the longest side length
For the first answer choice we add 7 and 8
7+8=15
The two shorter sides added are not greater then the longest side so that is not the answer
For the second answer choice we add
8 and 5
8+5=13
13 is not greater than 14 so this is not the answer choice either
For the third one we add 6 and 3
6+3=9 which is not greater than 10 so this is not the answer
For the last one we add 2 and 6
2+6=8 which is greater than 7 so this one is the answer

Okay so first you want to simplify the given equation (7x+3y)(7x-3y)
in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2
Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2

angle A and angle B are vertical anglesIf m angle A=(5x-3)^ and m angle B=(4x+21)^ then find the measure of angle A .
[PLEASE HELP]
Answer:
78
Step-by-step explanation:
5x3+4+21=78
Answer:
m<A=117°
Step-by-step explanation:
Based on the given from the problem, we know that angle A and angle B are vertical angles
Vertical angles are congruent; they have the same value.
we know that the measure of angle A is (5x-3)° and the measure of angle B is (4x+21)°
since we know they are congruent via vertical angles theorem, we can make the two values equal to each other
5x-3=4x+21
add 3 to both sides
5x=4x+24
subtract 4x from both sides
x=24
we found the value of x. However, the question asks for the value of angle A, which is (5x-3)°
we substitute our known value to find the value of angle A
m<A= (5*24-3)°
m<A=(120-3)°
m<A=117°
the measure of angle A is 117°

A basket ball player attempts 15 baskets in a game . He makes 9 of the attemps what is the ratio
Answer:
9:15 or 3:5
Step-by-step explanation:
A ratio can compare a part of a whole to a whole.
In this case, our whole is the total number of shots attempted: 15.
The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.
Put these values in a ration.
part:whole
9:15
Notice that 9 and 15 can be simplified by dividing both numbers by 3.
3:5
This is your simplified ratio.
Hope this helps!

A man walks due west for 4 km. He then
changes direction and walks on a bearing of
197° until he is south-west of his starting point.
How far is he then from his starting point? with workings
Answer:
Step-by-step explanation:
Let the starting point be B and the stopping be C as shown in the diagram below.
therefore, the angle at A will be (197-90)degree = 107degree
the angle at B is 45degree, since it is directly south west of C.
therefore the angle at C will be A+B+C=180 degree(sum angle of a triangle)
107+45+C=180
therefore, C=180-107-45=28degree
therefore, using sine rule gives;
sinA/a =sinC/c
sin107/a=sin28/4
0.9563/a=0.4695/4
0.9563/a=0.11736
therefore, a =0.9563/0.11736=8.148=8.1km(approx.)

Answer: Choice A
f(1) = 2
f(n) = 2*f(n-1) for n ≥ 2
===========================================================
Explanation:
n = term number
So for instance, n = 3 represents the index for the 3rd term
We see that when n = 1, f(n) = 2 as shown by the left-most red point.
This means that f(1) = 2 which is a short way of saying "the first term is 2".
So the answer is between A and C.
Let's randomly guess that it might be choice C. We'll use the recursive rule given to generate the next term
f(n) = 4*f(n-1)
f(2) = 4*f(2-1) .... replace every n with 2
f(2) = 4*f(1)
f(2) = 4*2 ..... replace f(1) with 2, since f(1) = 2
f(2) = 8
This tells us that the 2nd term is 8, but the graph says it should be 4. Note the red point at (2,4)
Ultimately this all means that we can eliminate choice C and go with choice A as the final answer.
As a check, let's plug n = 2 into the recursive rule for choice A
f(n) = 2*f(n-1)
f(2) = 2*f(2-1)
f(2) = 2*f(1)
f(2) = 2*2
f(2) = 4
We get the proper second term. I'll let you check the other remaining terms. The notation 2*f(n-1) means "multiply 2 by the previous (n-1) term". In other words, the term values are doubling {2,4,8,16,...}

A batsman scored the following runs in his first six innings. 58,73,21,77,99,32. Find the mean of the runs scored by him.
Answer:
60
Step-by-step explanation:
A Batman scored the following runs
58, 73, 21, 77, 99, 32
The mean can be calculated as follows
= 58+73+21+77+99+32/6
= 360/6
= 60
Hence the mean is 60
