Answer:
26 Minutes.
Step-by-step explanation:
Kevin started his science test at 
He finished the test 75 minutes later.
Now: 75 Minutes = 1 hr 15 Minutes
2:34 + 75 Minutes
=2:34+1:15
=3:49 P.M.
Kevin finished his test by 3:49 P.M.
Kevin has football practice at 4:15 P.M.
Therefore, the time Kevin had between the end of the test and the beginning of football practice
=4:15 P.M.-3:49 P.M.
=26 Minutes.

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:
Answer:
