Answer:

9/5

Step-by-step explanation:

The slope between the two points can be found by ...

m = (y2 -y1)/(x2 -x1)

m = (-16-2)/(-10-0) = -18/-10

m = 9/5

The slope of the line is 9/5. Perhaps this is a match to choice A.

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

The answer is C. This is because when you covert the fraction into a decimal, you get 2.33333(etc) and the decimal doesn’t end.

Effectus [21]

Answer:

It depends on how long the measurement is for each amount of money for example every 5 miles pay $12 so it would be which would be 11$.5 and the equation would be $12/5mi and if he had to pay $138 then it shows that he went 11.5 mi
