The x intrercepts is where the function crosses the x axis; In other words, it is where the output of the function is 0.
In a quadratic, you can start by factoring, if it’s unable to be factored then use the quadratic formula. Also, it is good to use the discriminate.
D= Discrimminate
D>0 2 real solutions
D=0 1 real solution
D<0 2 imaginary solutions.
The discrimminate is the equation/expression under the radical of the quadratic formula. With this formula, it’s not factorable. Using the discriminate it is also seen, as you’ll get a negative in the square root. This is imagenary because you cannot take the root of a negative value, which is why “i” is used to represent the square root of negative one.

Answer:
"125 callers" is the right answer.
Step-by-step explanation:
Given values:
Arrival calls rate,
= 25 per minute
Talking time,
= 4 minutes
Hold time,
= 1 minute
The flow time will be:
= 
= 
Flow rate,
= 
= 
By using the Little's law,
⇒ 
By substituting the values, we get


Thus the above is the correct approach.
Step-by-step explanation:
t= how far his scooter can travel on 2.5 gallons of gas
Start by setting up a ratio
53:1= t:2.5
Rewrite as fractions
=
Cross multiply
1(t)= 53(2.5)
Simplify
t= 132.5
Walter's scooter can travel 132.5 miles on 2.5 gallons of gas
I hope this helps!!!
