$\bf \sum\limits_{i=1}^{15}\ 5i-1\implies 5\sum\limits_{i=1}^{15}\ i-\sum\limits_{i=1}^{15}\ 1\implies 5\left[ \cfrac{15(15+1)}{2} \right]-(15\cdot 1)
\\\\\\

The path of water from a hose on a fire tugboat can be approximated by the equation y=-0.0055x^2 +1.15x + 5, where y is the heig

Komok [63]

Answer:

The water is 208.22ft from the tug boat

Step-by-step explanation:

The governing equation is $y=-0.0055x^2 +1.15x + 5$

y is the height above the ocean

x is the distance from the tugboat

if y= 6ft, the equation will now become

$6=-0.0055x^2 +1.15x + 5$

we can arrange this properly to form a quadratic equation by grouping like terms.

$-0.0055x^2 +1.15x -1=0$

solving quadratically we have two values of x as 208.22ft and 0.873 ft.

We can take a more realistic value as a solution to our problems:

208.22ft
