You can either find the roots of the quadratic formula using the quadratic formula two find the halfway point or you can use the formula t=-b/2a.  Both of the two methods gives you the axis of symmetry (the t value for the vertex).
I will use the second method since I don't like using the quadratic formula.
t=-32/(2x-16)
t=1 second
After you find the t value for the axis of symmetry, you plug it into the formula of the graph to find the height.
h=-16+32+14
h=30 feet

A school trip to a museum cost $2,056. A total of 125 chaperones and students went on the trip. Adult admission to the museum co
salantis [7]

Answer:

117 students, 8 adults

Step-by-step explanation:

Let's say a adults went and s students went.

Total cost for adults = 23 for each a = 23a

Total cost for each student = 16s

Number of adults and students = a + s = 125

Total cost = 23a + 16s = 2056

a + s = 125

23a + 16s = 2056

We can solve this by solving for a and then plugging that into the other equation, making it so that there is only one variable

subtract s from both sides in the first equation

a = 125 - s

plug that into the second equation

23(125 - s) + 16s = 2056

2875 - 23s + 16s = 2056

2875 - 7s = 2056

subtract 2875 from both sides to isolate s and its coefficient

-7s = -819

divide both sides by -7 to isolate s

s = 117

a = 125 - s = 125 - 117 = 8
