A surveyor is working to determine the gradient of a hill. The surveyor knows the hill starts at an elevation of 1755 feet and peaks at an elevation of 2105 feet. The distance of the hill from the bottom to the top is 910 feet. Select the responses that represent the angle of elevation of the hill (rounded to the nearest degree) and the trigonometric functions of the angle of elevation.
a. Cosθ= 13/5
b. Cosθ= 12/13
c. Cosθ= 13/12
d. Cosθ =13/5
Answer:
cos∅ = 12 / 13
Hence; Option b) Cosθ= 12/13 is the correct answer
Step-by-step explanation:
Given the data in the question;
the height( opposite ) = 2105 ft - 1755 ft = 350 ft
the hypotenuse = 910 ft
adjacent = x
as its illustrated in the image uploaded along this answer;
using the Pythagoras theorem
910² = 350² + x²
x² = 828100 - 122500
x² = 705600
x = √705600
x = 840 ft
Now
cos∅ = adjacent / hypotenuse
cos∅ = 840 / 910
we simplify; divide through by 70
cos∅ = 12 / 13
Therefore; Option b) Cosθ= 12/13 is the correct answer

Answer:
Is there any more to this question?
Step-by-step explanation:
Answer:
It is proportional.
Step-by-step explanation:
y/x = 7
Solve for y.
y = 7x
The equation of a proportional relation is of the form:
y = kx
y = 7x is of the form y = kx, so y/x = 7 is proportional.

how many phone numbers (without area codes) are possible? the first digit cannot be 0 or 1
Answer:
Each three-digit area code may contain up to 7,919,900 unique phone numbers:
NXX may begin only with the digits [2–9], providing a base of 8 million numbers: ( 8 x 100 x 10000 ) .
However, the last two digits of NXX cannot both be 1, to avoid confusion with the N11 codes (subtract 80,000).
Despite the widespread usage of NXX "555" for fictional telephone numbers — see 555 (telephone number) — today, the only such numbers specifically reserved for fictional use are "555-0100" through "555-0199", with the remaining "555" numbers released for actual assignment as information numbers (subtract 100).
In individual geographic area codes, several other NXX prefixes are generally not assigned: the home area code(s), adjacent domestic area codes and overlays, area codes reserved for future relief nearby, industry testing codes (generally NXX 958 and 959) and special service codes (such as NXX 950 and 976). Subtract for 911 411etc emergency and informational numbers

There are total 8 X 10⁹ possible 10 digit phone numbers whose first digit cannot be 0 and 1.
What is Permutation?A permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.
Here, well the first digit is not allowed to be 0 or 1 so 8 (2 to 9) remain to choose.
For the reminding 8 numbers you can make any choice from 00000000 to 99999999 when you count them these are 10⁹ possibilities and when you consider the 8 possibilities you have for the first number there are 8X10⁹ possibilities total.
Thus, there are total 8 X 10⁹ possible 10 digit phone numbers whose first digit cannot be 0 and 1.

Ava is attending a school orchestra
concert. She sees her math teacher
seated 5 feet ahead of her and her
science teacher seated 12 feet to her
right. How far apart are the two
teachers? If necessary, round your
answer to the nearest tenth.
Answer:
The two teachers are 13 feet apart
Step-by-step explanation:
Right Triangles
Ava, her math teacher, and her science teacher form a right triangle in which she is at the 90° vertex.
The distances from the three people must satisfy the Pythagora's theorem, where the distance between the two teachers (D) is the hypotenuse, thus:
[tex]D=\sqrt{5^2+12^2}[/tex]
[tex]D=\sqrt{25+144}[/tex]
[tex]D=\sqrt{169}[/tex]
D = 13 feet
The two teachers are 13 feet apart

Answer:
e. An online retailer reaches out only to its customers who have left positive reviews for its product and asks them to complete a survey of their experience with the retailer's products
Step-by-step explanation:
A sampling error happens when a sample has some kind of a bias.
One example is for example, sampling only members of one political party about a new bill.
In this question:
The correct answer is given by option e, because the retailer will have the opinions only from those with positive reviews, basically disconsidering those with negative reviews, and not giving them a clear idea of their service.

The high temperature, in ∘C, on the first day of winter was recorded in a certain city every year from 1915 to 2015. The following six temperature values were randomly selected from the data.
4,12,6,9,6,11
To determine the "spread" of the data, would you employ calculations for the sample standard deviation, or population standard deviation for this data set?
Answer:
Population standard deviation
Step-by-step explanation:
Mean value = 4 + 12 + 6 + 9 + 6 + 11 = 48 / 6 = 8 mean
Standard deviation with numbers close together in random samples show the numbers would be close to their average mean and would never show spread of data in lower range numbers
Range = 12 - 4 = 8 does not determine the ''spread'' for measures such as temperatures it shows the mean also as unintended.
Criteria must include lowest and highest temperature to reflect 100 years and so population standard in lower set data would reflect a reliable calculation.
As the condition has mentioned in the problem , population standard deviation would be prefer for this data set
Temperature range for year 1915 to 2015 has been given in question
= 4, 12, 6, 9, 6, 11
The standard deviation is used to calculate the spread of values in the set of data.
Mean = (4 + 12 + 6 + 9 + 6 + 11)/6
48/6 = 8
mean = 8
[tex]\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]
σ= population standard deviation
N= population size
xi= each value from the population
μ = population mean
Range = 12-4
=8
since the range is very small difference to its extreme points on sets of temperature relative b the year difference which is a century i.e, 100 years . Though, Its implies formula that has been mentioned above which is of standard deviation for population shows the perfect calculation for this lower range of temperature gives the precise information of the spread.
Thus, Population standard deviation would be preferred for the further calculations.

Please explain your answers
Step-by-step explanation:
Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,
[tex]\frac{x}{y} * \frac{a}{b }= \frac{x*a}{y*b}[/tex]
Addition and subtraction requires that we find a common demoninator.
For example,
[tex]\frac{6}{4} + \frac{4}{3}[/tex]
The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.
[tex]\frac{6}{4}*\frac{3}{3} + \frac{4}{3} \frac{4}{4} = \frac{18}{12}+\frac{16}{12}[/tex]
Then we add the numerators
[tex]\frac{18+16}{12} = \frac{32}{12}[/tex]
Then we should reduce.
[tex]\frac{16}{6} = \frac{8}{3}[/tex]
Division is a little trickier because we have to flip-flop the second term and then multiply. For example: [tex]\frac{1}{10} \div \frac{5}{6} \rightarrow \frac{1}{10} * \frac{6}{5} = \frac{6}{50}[/tex]
