Answer:
a = - 
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (105, 27 ) , thus
y = a(x - 105)² + 27
To find a substitute (109, 14 ) into the equation
14 = a(109 - 105)² + 27 ( subtract 27 from both sides )
- 13 = 16a ( divide both sides by 16 )
a = - 
112.5 minutes
Since there are 60 minutes in 1 hour so multiply that by 3 and you get 180 minutes
180➗8=22.5
22.5✖️5= 112.5 minutes
Hope this helps! :3
