Answer:
Step-by-step explanation:
The equation of a quadratic function in vertex form is given by:
Where (h,k) is the vertex.
It was given in the question that the vertex of the parabola is (-1,4).
When we substitute the vertex into the formula we get:
The parabola also passes through (4,19) hence it must satisfy its equation.
We divide both sides by 25 to get:
Hence the quadratic function is:
Yes this is proportional!

Answer:
The answer is 95
Step-by-step explanation:
The speed is 64 miles per hour
Step-by-step explanation:
Lets define speed first.
"Speed is the distance per unit time"
Speed is denoted by s.
Given
Distance = d = 160 miles
Time = t = 2.5 hours
Hence,
The speed is 64 miles per hour
