Log algebra question

True or False 2log10 ^ x = x^2-You can move the x exponent down to the front for 2xlog10 =x^2. The log 10 cancels because its log base 10 of 10, which is equal to 1. Then you have 2x=x^2, which is fa

If x=cos(3t) and y=sin^2(3t), what is dy/dx and d^2y/dx^2

∵ x = cos 3t, y = sin² 3t ∴ x² + y = cos² 3t + sin² 3t = 1 ∴ y = 1 - x² ........................................… (1) ∴ dy/dx = -2x ..................................... (2) ∴ d²y/dx² = -2 .......

Probability: Rolling a 10-side dice, 10 times ending in 90+

So, 1 10-sided dice, rolling it 10X, getting a number higher than 90? Hm, so my guess is since getting a 10 is 1/10 or 10%...and then multiplying it by 10 again is gonna be 1/100 so 1%...but...its mor
