Answer:
√6 + √2
= --------------
4
Step-by-step explanation:
15° = 45° - 30°
So
cos(15) = cos(45 - 30)
=cos(45) × cos(30) + sin(45) × sin(30)
= 1/√2 × (√3)/2 + 1/√2 × 1/2
(√3) + 1
= --------------
2√2
(√3) + 1 √2
= -------------- x ---------
2√2 √2
√6 + √2
= --------------

Answer:
2 so b is the answer
Step-by-step explanation:
Answer:
I'm pretty sure the answer is still 6x-5.
Step-by-step explanation:
Answer:
There's no negative sign in front of the absolute value so it opens upward. As for the vertex, the x value will be whatever makes what is in the absolute value symbols 0 which is 2.5 in our case and the y-coordinate is 3 so the vertex is (2.5, 3).
