Step-by-step explanation:
One is given the following equation;
The problem asks one to find the roots of the equation. The roots of a quadratic equation are the (x-coordinate) of the points where the graph of the equation intersects the x-axis. In essence, the zeros of the equation, these values can be found using the quadratic formula. In order to do this, one has to ensure that one side of the equation is solved for (0) and in standard form. This can be done with inverse operations;
This equation is now in standard form. The standard form of a quadratic equation complies with the following format;
The quadratic formula uses the coefficients of the quadratic equation to find the zeros this equation is as follows,
Substitute the coefficients of the given equation in and solve for the roots;
Simplify,
Therefore, the following statement can be made;
Answer:
Option D.
Step-by-step explanation:
-If the attached graph shows the distance above sea level to which Bethanie's leads as a function of time, then we can observe that after having elapsed 8 minutes Bethanie's is a distance of 0 from sea level.
The graph shows that the value of B(t) is always less than 1 during the 8 minutes of travel.
-On the other hand, the function that models the distance above sea level that Mike drives as a function of time, shows us that after 3 minutes the distance M(t) begins to increase rapidly until at t = 8 minutes:
.
Therefore the correct option is D
The person who leads to the highest elevation is Mike.
