52.8 because 5,280/100=52.8
So the knot is 52.8


Recall that

, which is to say

has period

. This in turn means that

will have the same solutions as

for any integer

. So the general solution to the first case is

where

is any integer.
On the other hand,

but

for any value of

, so this equation has no (real) solutions for

.
Answer:
y^3 + 12y^2 + 48y + 64
Step-by-step explanation:
Cumplimos la regla del cubo
y^3+(3y^2*4)+(3y*4^2 )+4^3
Operamos factores comunes
y^3+(12y^2 )+(48y)+64
A = a+b
——- h
