Answer:

Step-by-step explanation:
Comparing it with quadratic equation
, we get:
a = 1 . b = 4 and c = 5
So,
Discriminant = 
D = (4)²-4(1)(5)
D = 16 - 20
D = -4
Hence,
Discriminant = -4

84 is the answer
Answer:
$1467
Step-by-step explanation:
We must convert the first 3 values to yards as so: 5 ft, 4 ft, and 8 inches. We then convert 8 inches to 2/3 feet. multiply 5*4*2/3 to get 13 and 1/3. multiply that by 110, to get 1466 and 2/3. Round it to $1467
The phase shift is 7.2 right
