Answer:
( 3n-8)
Step-by-step explanation:
so the given sequence is AP
where common difference is +3
nth term for this AP will be
(-5)+(n-1).(3) = 3n-8
Add the time to the start time:
8:30
1 hour: 9:30 am
2 hours: 10:30am
3 hours: 11:30am
4 hours: 12:30pm
5 hours: 1:30pm
Then 45 minutes makes the time 2:15pm
Answer: 2:15 pm
According to the vertex and the directrix of the given parabola, the equation is:

<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:

In which a is the leading coefficient.
The directrix is at y = k + 4a.
In this problem, the vertex is (1,4), hence:

The directrix is at y = 7, hence:


Hence, the equation is:
