Sin5x + sin3x = 2sin4x.cosx
cos5x + cos3x = 2cos4x.cosx
so
=
= tan4x
the answer is C (0,0) because thats the only choice that is in the blue shaded area on the graph
you can also test it by plugging in 0 into the equation and your answer will be true meaning that (0,0) is a correct answer
Answer:
C
Step-by-step explanation:
If you look at the graph, you notice there is no data to determine the slope, but there (0,b) represents the y-intercept. So my guess is, they give you a clue what the slope is already, but if you notice the y-intercept lowers the linear line a few notches because (0,18) is lower than the (0,30). That is what I would choose as the answer
Answers: The page numbers are 11 and 12
==========================================================
Explanation:
Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.
Let,
- x = first page, some positive whole number
- x+1 = second page, follows immediately after page x
Adding those two said pages will lead to 23
first + second = 23
(x) + (x+1) = 23
2x+1 = 23
2x = 23-1
2x = 22
x = 22/2
x = 11 is the first page
x+1 = 11+1 = 12 is the second page
Check: 11+12 = 23 which confirms the answers.
Is there a number on the left side by the 10?
