Answer:
D = 120, there are 2 real roots for F(x)
Step-by-step explanatU
using the
formula D = b^2 - 4ac for discriminant
D = 8^2 - 4*(-7)*2
D = 64 + 56 = 120

Answer:
200.96 square feet
Step-by-step explanation:
The amount of fencing Scott will need to buy can be gotten by calculating the area of the circular rock garden .
Area of a circle is given by
Pi r^2
Where
r = radius
Given diameter of 16 feet
r = diameter/2
= 16/2
= 8 feet
Pi = 3.14
Therefore,
Area = 3.14 x 8^2
= 3.14 x 8 x 8
= 200.96 square feet
The amount of fencing Scott will need to buy is 200.96square feet
Because to pay for other employees and for there taxes and others
