Answer:


Step-by-step explanation:
* Lets explain how to solve the problem
- We can write a sine as a cosine by translate the sine function to the
left by 
- 
∵ The value of sin(0 + π/2) = 1
∵ cos(0) = 1
∴ sin(0 + π/2) = cos(0)
∴ If sin(x) translated to the left by
, then it will be
cos(x)
∴ 
- <u><em>Vice versa</em></u>
- We can write a cosine as a sine by translate the cosine function to
the right by 
- 
∵ The value of cos(0 - π/2) = 0
∵ sin(0) = 0
∴ cos(0 - π/2) = sin(0)
∴ If cos(x) translated to the right by
, then it will be
sin(x)
∴

Answer:
8.2
Step-by-step explanation:
If each student in the group collected 15 shells, we know that there are 123 students on the field trip, so we can take 123 and divide it by 15 to get 8.2 or 41/5.
Answer:
B
The answer is B, which is -1.5.

Answer: x = 4
Step-by-step explanation:
To solve this problem, make use of the fact that you may add anything to an equation, as long as you do it to both sides.
Simply add 4x to both sides to get:
13 = 1 + 3x
Then simply add -1 to both sides to get:
12 = 3x
Then, divide both sides by 3 to get:
4 = x
