Prove that $\frac{1 + {log}_{5} 8 + {log}_{5} 2}{{log}_{5} 6400} = 0.5$ $(1 + Log_5 8 + Log_5 2)/log_5 6400 = 0.5$ Please note the base number of each log is 5 and not 10. I continuously get $\frac{1}{80}$ $1/80$ , can someone please assist?
How do you find the amplitude and period of $y = cos 4 x$ $y = cos 4x$ ?
I need help on this question as I've been stuck on it for quite a while.! also the range is in radians from 0 TO PI. solve for x? thank you!!
How do you find the domain and range of $y = \sqrt{x + 8}$ $y = sqrt(x+8)$ ?
How do you solve $\sqrt{2 x - 6} < 4$ $sqrt(2x-6)<4$ ?
Point A is at $(6, 2)$ $(6 ,2 )$ and point B is at $(3, - 8)$ $(3 ,-8 )$ . Point A is rotated $\frac{π}{2}$ $pi/2$ clockwise about the origin. What are the new coordinates of point A and by how much has the distance between points A and B changed?
