Make sure to multiply everything together, then check it with a calculater.
Hope this works:)
Answer:
280
Good luck on your exam tomorrow! :-)
Step-by-step explanation:
Multiply both sides by 2pi:
F(2pi) = sqrt(g/l)
Square both sides:
F^2 (2pi)^2 = g/l
Solve for l by dividing both sides by F^2 (2pi)^2
L = g/ F^2 (2pi)^2
Simplify:
L = g / 4pi^2(f^2)
8 to the power -2 = 8^(-2) is equal to 1/64, or 1 / (8^2). Are there any other correct answers? Experiment, please.
The answer is 40 set up a proportion with 60% over 100 and 24 on top of the other fraction.
