50/80 = 0.625
100 - 0.625 = 0.375
0.375 = 37.5% (move the decimal point to the right 2 spaces)
37.5% decrease is your answer
hope this helps
Cosh^2x - sinh^2x = 1
coshx = sqrt( 1 + sinh^2x)
= sqrt(1 + (8/15)^2) = 17/15
for tanh
just divide
sinhx/coshx = tanhx = 8/17
for sech , cosech, coth << just flip the original as normal trigonometric functions <span />
I think its 6 but im not sure
Answer:
n+(n+2)+20=4n
Step-by-step explanation:
Let the smaller integer be n,
the bigger odd integer will be n+2.
n+(n+2)+20=4n
2n+22=4n
2n=22
n=11
