Answer:
7.33333 hours
Step-by-step explanation:
Theo's speed = 55mph
Distance = speed * time
Distance covered after 2 hours
Distance = 55 * 2 = 110 miles (distance already covered by Theo when Dennis left
Dennis speed = 70mph
Let time taken to catch up = x
70x = 110 + 55x
70x - 55x = 110
15x = 110
x = 110 / 15
x = 7.33333 hours

1923+3=1926
Considering the vertex of the parabola, the correct statement is given by:
The range of the function is all real numbers less than or equal to 9.
<h3>What is the vertex of a quadratic equation?</h3>
A quadratic equation is modeled by:

The vertex is given by:

In which:
Considering the coefficient a, we have that:
- If a < 0, the vertex is a maximum point, which means that the range is all real numbers less than or equal to
.
- If a > 0, the vertex is a minimum point, which means that the range is all real numbers greater than or equal to
.
In this problem, we have that:
- a = -1 < 0, hence the vertex is a maximum point.
Hence the range is described by:
The range of the function is all real numbers less than or equal to 9.
