$\frac{740ft*1in}{8ft}=92,5in$

$\frac{800ft*1in}{8ft}=100in$

Write the function in vertex form, and identify its vertex. g(x) = 5x2 - 50x + 128

steposvetlana [31]

Hello :
<span>g(x) = 5x² - 50x + 128
= 5(x²-10x +128/5)
= 5 (x²-10x+5²-5² +128/5)
= 5 ((x-5)² +128/5 -125/5)
y = 5 ((x-5)² - 3/5)
y= 5(x-5)² +3.....vertex form
the vertex is : (5,3)</span>
