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:
1
Step-by-step explanation:
1x1 is 1 because 1x1 is 1
Answer: 2
(-4,1)(1,-2)
M=-2+4/1-1
=2/0
=2
In 1997 = 17697
Because, each year, the number of employees is expected to decrease by 2.2%, find 2.2% of 17697 and subtract from the number.
2.2/100 x 17697 = 38933.4/100 = 389.334
^that was calculating 2.2% of 17697. Now we subtract:
17697.000
- 389.334
17307.666 =
Round to the nearest whole number = 17308
Answer: in 1998, the expected number of workers is 17308
It doesn't change because to add fractions, you need a common denominator. To find it, they multiplied 1/3 by 2 to make 2/6, to add to the 3/6.
