Answer:
24.8 km
Step-by-step explanation
To do this we would just multiply 24.8 by 10,000 which is 248000 and if we divide that by 10000 (to get km) we would get 24.8km
Using the discriminant, the quadratic equation that has complex solutions is given by:
x² + 2x + 5 = 0.
<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>
A quadratic equation is modeled by:
y = ax² + bx + c
The discriminant is:
The solutions are as follows:
- If
, it has 2 real solutions.
- If
, it has 1 real solutions.
- If
, it has 2 complex solutions.
In this problem, we want a negative discriminant, hence the equation is:
x² + 2x + 5 = 0.
As the coefficients are a = 1, b = 2, c = 5, hence:

I think that 0 is the vertex
They are not similar. (Look at Angle A ; and angle D ; They are not similar; Angle D has "two curved lines" ; which corresponds with Angle C (in the other triangle ; that is, "Angle C" has two curved lines; where as Angle A does not.
As such, the triangles are NOT similar.

As such, the second part of the question is NOT APPLICABLE; that is, there are no "similarity ratio and corresponding statement.
