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).
To figure this out, subtract 15 from 7 and you get –8. So your answer is -8˚ C.

Answer:
53.52°
Step-by-step explanation:
The cosine function relates the angle to the sides shown:
Cos = Adjacent/Hypotenuse
cos(x°) = (22 ft)/(37 ft) = 22/37
The inverse cosine function is used to find the corresponding angle.
x° = arccos(22/37) ≈ 53.52°
The sequence is subtracting 5.5 each time:
19 - 5.5 = 13.5
30 - 5.5 = 24.5
24.5 - 5.5 = 19
so 24.5, or 24 1/2 is your answer
hope this helps
