U need to find the square root by long division.
So the answer would be 2.2
Answer:
About 90.73 meters/min.
Step-by-step explanation:
Dimensional analysis is done by multiplying the wanted unit over the current unit in equal measure, or the other way around.
First, we will convert feet to meters, using that 1 ft = .4048 m.
32ft/6.45sec * .3048m/1ft = 32/6.45sec * .3048m = 9.7536m/6.45 sec.
Second, we convert seconds to minutes, using that 60 sec = 1 min.
9.7536m/6.45sec * 60sec/1min = 9.7536*60m/6.45min ≈ 90.7311627m/min.
f(x)=4x
To find the inverse, first change f(x) to y:
y = 4x
Now switch the variables:
x = 4y
Solve for Y:
Divide both sides by 4:
y = x/4
Now replace y with the inverse function f^-1(x):
f^-1(x) = x/4
