Answer: 70
Step-by-step explanation:
10 x 7
To determine the sum of the arithmetic series, simply remember that i is the pattern that you are going by which is 1,2,3.
The top value on the sigma sign tells you the final value that you must go to.
So use the equation to go from 1 to 18. So it would be 2(1) + 9 + 2(2) + 9 etc.
Answer:
D
Step-by-step explanation:
The arcsine (
) function of x is defined as the inverse sine function of x when -1≤x≤1.
So, when
we have that
This gives us the domain 
of the function 
The range of the function 
is 
so the range of the function 
is the same (options A and C are false).
When x=-4,
So, option B is false and option D is true.
I'd say D. A uses words that suggest the author has an opinion of Alex's behavior that is unfavorable. B uses the words "obviously less disciplined" to refer to Sue, which is clearly an opinion and also rather unfavorable. C makes assumptions as to Joan's emotions toward Mary, which cannot be ascertained objectively without asking Joan. D is a clear statement of the facts without embellishment.
EDIT: Note that the definition of objective is not influenced by opinions or beliefs, as opposed to subjective.
