$\\ \rm\rightarrowtail y=x^2-10x+16$

$\\ \rm\rightarrowtail y=x^2-10x+16+9-9$

$\\ \rm\rightarrowtail y=x^2-10x+25-9$

$\\ \rm\rightarrowtail y=(x-5)^2-9$

Vertex form

y=a(x-h)^2+k

So

vertex:-

(h,k)=(5,-9)

A boat traveled 27 miles in 2 hrs. At this rate, How many miles will the boat travele in 1/2 hrs

Mashcka [7]

Answer:

In explanation down below.

Step-by-step explanation:

So if the boat was able to travel 27 miles in 2 hours that means that it traveled 13.5 miles an hour. I think that you want to know how many miles the boat will travel in 1/2 an hour. Which is 6.75.

1 hour: 13.5 miles

1/2 hour the boat has traveled 6.75 miles.

I hope this helps!!!
