Answer:
= 5n - 22
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₂ = - 12 , then
a₁ + d = - 12 , that is
a₁ + 5 = - 12 ( subtract 5 from both sides )
a₁ = - 17
Thus
= - 17 + 5(n - 1)
= - 17 + 5n - 5
= 5n - 22

Answer:
Estimate angle of elevation = 15.4°
Step-by-step explanation:
Given:
Start elevation = 9,400 ft
Ends near the summit = 14,255 ft
horizontal distance = 17,625 ft
Find:
Estimate angle of elevation.
Computation:
⇒ Total elevation distance = Ends near the summit - Start elevation
⇒ Total elevation distance = 14,255 - 9,400
⇒ Total elevation distance = 4,855 ft
⇒ Tan A = 4,855 / 17,625
⇒ Tan A = 0.2754
⇒ Tan A = 15.4°
Estimate angle of elevation = 15.4°

The mathematical proofs are useful to show that a mathematical statement is true. Generally a mathematical proof use other statements like theorems, or axioms. Also mathematical proofs are useful to know if the development of a theoretical process in other areas like physics is well done. Other thing that is useful of the proofs in mathematics is that it use a formal language with symbols that minimize the ambiguity and make it universal.

The temperature change is: 12°F
How to calculate the temperature change?
The temperature change from 6 a.m. to 11 a.m. can be calculated by subtracting the initial temperature from the final temperature.
In this case, the initial temperature at 6 a.m. was -12°F and the final temperature at 11 a.m. was 0°F.
Therefore, the temperature change is 0°F - (-12°F) = 12°F. So, the correct answer is C) 12
