Given from the question
Vertex
(h,k) = <span>(500, 15900)
One of the points on the graph
(x,y) = (0,8400)

FIRST PART: Find the quadratic function
We can find the quadratic function by this formula
y = a (x - h)</span>² + k

Input the numbers to the formula, to find the value of a
y = a (x - h)² + k
8400 = a(0 - 500)² + 15900
8400 = a (500)² + 15900
8400 = 250000a + 15900
-250000a = 15900 - 8400
-250000a = 7500
a = 7500/-250000
a = 0.03

Submit a to the formula
y = a (x - h)² + k
y = 0.03 (x - 500)² + 15900
<em>(This is the quadratic function)

</em>SECOND PART: Find the linear function

dsp73

Answer:

2 hours

Remember that time = distance/rate

The distance you need to cover is 56 miles, while you go 28 miles per hour. Using these, we get this:

time=56/28

time=2

So it will take two hours to go across a 56 mile wide bay at 28 mph.
