The equation to calculate percent error is # experimental - #theoretical / # theoretical * 100. The experimental value is 24 and the theoretical value is 42. Here's the calculation 24-42/42 * 100 = -42.86 rounded. Hope this helped :))
45.2 is the constant hope this helps! please give branliest
Step-by-step explanation:
You have to do first and second derivatives :
y = a sin 3x + b cos 3x
dy/dx = 3a cos 3x - 3b sin 3x
d²y/dx² = - 9a sin 3x - 9b cos 3x
Next, you have to compare it :
let d²y/dx² = ky,
-9a sin 3x - 9b cos 3x = k(a sin 3x + b cos 3x)
-9(a sin 3x + b cos 3x) = k(a sin 3x + b cos 3x)
Therefore, k is equals to 9.
