Diameter- The line that goes through the circle is the diameter to find the diameter take the radius and multiply it by two
Circumference- Take the radius divide by two and multiply by pi which is 3.14
A would be the correct answer! because x represents the number of miles (charged at .8) and 5.40 is a flat rate
Answer:
A, D
Step-by-step explanation:
When we multiply the fractions, we can get:
This is also equivalent to:
When looking at the answer choices, the only ones that equal are A and D because:
Answer:
the function has two distinct real roots.
Step-by-step explanation:
D=b²-4ac
D<0 No real roots
D=0 One real root
D>0 Two distinct real root.
(-5)²-4*1*-3
25+12
37
Since D is > than 0, the function has two distinct real roots.
