The height of a flare fired from the deck of a ship in distress can be modeled by h = -16t2 + 104t+ 56, where h is the height in feet of the flare above water and t is the time in seconds. Find the time it takes the flare to hit the water.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

y-3=-3/2(x+4)
