Answer:

37

Step-by-step explanation:

f(x) = 2x-1

g(x) =x^2 +3

f°g(x) = means put g(x) in for x into the function f(x)

f(g(x)) = 2 (g(x)-1

           =2(x^2 +3) -1

    Distribute

           = 2x^2 +6-1

           =2x^2 +5

Now we let x=-4

f(g(-4)) = 2 (-4)^2 +5

           =2(16) +5

            =32+5

            =37

Which of the following observations of children is the most objective?
Ivan
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.

Can someone help me with theses problems?
madreJ [45]

Answer:

17. 50

18. 150

19. 240

20. 20

21. 60

22. 240

23. 150

24. -240

25. 222

26. 75

27. 300

28. 340

29. 175

30. 265

31. 298

32. 118

Step-by-step explanation:

How you find co-terminal is by adding or subtracting 360 degrees to the value you are given.

If it is a positive number like #18. all you do is subtract 510 - 360 = 150 until you get to a value between 0 degrees and 360 degrees.

The same thing applies to negative numbers. Like #21. You will add 360 + (-660) until you get to a number between 0 degrees and 360 degrees.

-660 + 360 = -300 (this is not a value in between 0 and 360 so we must add 360 again)

-300 + 360 = 60 (this is a value in between 0 and 360) (this is the co-terminal angle)

That is the idea of finding co-terminal angles.
