Maria is practicing for her piano recital. she practices for 3 days on day one she practices for 45 minutes, on day 2 she practices for 90 minutes on day 3 she practices for 135 minutes. by how much did she increase the time she practiced each day?

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

angle efh= angle egh

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
