ANSWER:

f(x)=-2x-2

This is because at 0, the function equaling -2 can be easily determined by adding a -2.
The first portion can be determined by simplifying 4 and 2 into -2. (Negative for the decrease)

Answer:

The function is -2x - 2.

Step-by-step explanation:

When x  = 0  f(x) the dependent variable = -2.

So we have the linear function f(x) = mx - 2 where m is the slope of the line.

When x increases by 2 . f(x) decreases by 4  so we can make a table:

x  f(x)

0   -2

2   -6

4   - 10

So m =  (-10 - -6) / (4 - 2) =    -4/2 = -2

The function f is -2x - 2.

UkoKoshka [18]

Answer:

51.63 ft

Step-by-step explanation:

Tangent 25 = opposite / adjacent

tan 25 = height/100

Height = 100 tan 25 = 46.63 feet ABOVE the head of the victim

victim head height = 5 ft

46.63 + 5 = 51.63 ft
