Answer: Choice B) -infinity < x < infinity
==========================================================
Explanation:
The parabola goes on forever to the left and to the right. We can plug in any x value without worrying about something as a division by zero error. So any real number will work.
Writing -infinity < x < infinity refers to the entire number line, which is the set of all real numbers.
Answer:
5 1/8 feets
Step-by-step explanation:
Given that:
PLAN A:
Length of post = 4.25 feets
Post must be 7/8 feets below the ground
Height of fence in PLAN A :
Converting 4.25 feets to decimal :
4.25 feets = 4 feets + 0.25 feets
0.25 feets = 1/4 feets
4 + 1/4 feets = 4 1/4 feets
4 1/4 feets + 7/8 feets
17 /4 feets + 7 /8 feets = [(34 + 7) / 8] feets
[(34 + 7) / 8] feets = 41/ 8 feets
41 / 8 feets = 5 1/8 feets
7.92 is less than 8
10.21 is less than 11
8*11=88
the answer is less than 88.
the answer seems to be unreasonable to me it's too high
Y=6 because if you break it down you get (11y+7) =73 then you subtract 7 from both sides to get 11y=66 then you divide 11 on both sides to get y=6
