Hey there!
Here is your question -
In this equation, you're looking for n alone. To keep the variable alone, you have to do the opposite of what's happening to the variable.
In this equation, 12 is being added to n. The opposite of that is subtracting 12.
Subtract 12 from both sides -
Your answer is -8.
Hope this helps! :)
If the same pattern continues then kevin should be swimming a distance of 50 meters in 0.5 minutes.
just subtract 0.2 weekly if the pattern continues
Answer:
2260.8 ft ^ 2 / s
Step-by-step explanation:
To solve the problem we first know that:
dr / dt = 6 ft / s
r = 60 ft
Now they ask us for dA / dt, the change of the area with respect to time, by chain rule we have to:
dA / dt = dA / dr * dr / dt
we have that A = pi * r ^ 2
d (pi * r ^ 2) / dr
deriving the above we are left with:
2 * pi * r
replacing:
dA / dt = (2 * pi * r) * 6
dA / dt = 2 * 3.14 * 60 * 6
dA / dt = 2260.8 ft ^ 2 / s
therefore the area change per second is 2260.8 ft ^ 2 / s
