Answer:
62 miles/hour
Step-by-step explanation:
You can solve this the way you would solve any other "averaging" problem.
(50 + 50 + 70 + 70 + 70) / 5 = 62
He traveled 50 mi/hr for the first 2 hours and 70 mi/hr for the remaining (3 hours). Add up all the values and divide by the amount of hours (5).
Answer:
Step-by-step explanation:
we know that
The quadratic equation is a vertical parabola
The axis of symmetry in a vertical parabola is a vertical line
The equation of the axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex
The x-coordinate of the vertex is equal to the formula
therefore
the equation of the axis of symmetry is equal to
Option (A) is correct, the conjugate of denominator will be √10+2
