The direct variation that can be established using the given parameters is that, the time it takes between seeing the lightning and hearing the thunder is directly related to the speed.
However, it can also be established that the time described above is inversely proportional to the distance. This can be written as,
t = k/d
We substitute the given expression for each of the known terms. t is time, s, and d is distance, 3s.
s = k/3s
The k written in the equation is the constant of proportionality.
Answer:
Step-by-step explanation:
f(x) = x + 2.....change f(x) to y
y = x + 2....now switch x and y and solve for y
x = y + 2
x - 2 = y....change y to f-1(x)...represents an inverse
f-1(x) = x - 2 <== ur inverse
Answer:D.51
Step-by-step explanation:180-68-61=51
You don't even have to actually do the division to find the correct answer.
The leading term of q(x) is x³/x² = x, so only the 1st and 3rd selections are appropriate.
The remainder r(x)/b(x) will have the divisor as b(x), so only ...
.. the 1st selection is appropriate.
