Amplitude is 4
I don’t know the cos function, sorry :(
For a function to be a function there cannot be any x’s repeated. In this case, you’re looking for a function that has an x repeated. The answer is {(1,1),(1,2),(1,3),(1,4)}
Step-by-step explanation:
In this given figure vertical opposite angles are equal
6x+7=8x-17
2x=24
X=12
Answer is 11 radical 6, C.
Answer:
In bold below.
Step-by-step explanation:
a) Arithmetic sequence with common difference 3 and first term = 2:
nth term = 2 + 3(n - 1)
= 3n -1.
b) Similar to above with common difference 2 and first term = 9.
nth term = 9 + 2(n - 1)
= 2n + 7.
