Wider after the boat passes. The wake is the same width as the boat when it first forms, and then it gets wider in proportion to the square root of the distance from the boat. If a 2-meter wide boat passes your
position at 5 m/sec, which domain is appropriate for a function that
models the width of the wake, f(x), and the distance from the boat, x?

a) all numbers greater than 2

b) all rational numbers

c) all positive numbers

d) all numbers greater than 5

y=mx+b

step-by-step explanation:

m slope, b y-intercept

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

6e14 is the answer.
