For this case we have the following equation:
f (x) = x ^ 2 + bx-49
Deriving we have:
f '(x) = 2x + b
We match zero:
0 = 2x + b
We clear x:
x = -b / 2
The axis of symmetry is at x = 8, therefore:
x = -b / 2 = 8
Clearing b:
b = -2 * (8)
b = -16
Answer:
the value of b is:
b = -16
Answer:
96,190 sq m
Step-by-step explanation:
96,187
7 is greater than 5 so we round up
8 + 1 is 9
Therefore 96,187 rounded to the nearest ten is 96,190
Hope this helped~
