we know that
The formula to calculate the <u>roots</u> of the <u>quadratic equation</u> of the form 
is equal to
where
The <u>discriminant</u> of the <u>quadratic equation</u> is equal to
if 
----> the <u>quadratic equation</u> has two <u>real roots</u>
if 
----> the <u>quadratic equation</u> has one <u>real root</u>
if 
----> the <u>quadratic equation</u> has two <u>complex roots</u>
in this problem we have that
the <u>discriminant</u> is equal to 
so
the <u>quadratic equation</u> has two <u>complex roots</u>
therefore
the answer is the option A
There are two complex roots
Answer:
9.5 hours
Step-by-step explanation:
Your general equation is this:
y = mh + b
There is no b value because there is no starting value of miles.
y is the total number of miles driven. m is the amount of miles per hour. h is the number of hours.
570 = 60h
To find h, divide both sides by 60.
h = 9.5 hours
