C=pid
d=diameter
d=4
C=4pi
tada
if you want
aprox pi=3.14
C=12.56 units
Answer:
Step-by-step explanation:
so if you put Ln(0.99) into your calculator it gives you a negative answer. so we know that this problem will be decay.
next the answer for the above looks like 0.010050 ... so it's 1.0% for each x
H(x) = 0.15x - 0.19
p(x) = 0.29x - 0.16
(p · h)(-8) = (0.29(-8) - 0.16)(0.15(-8) - 0.19)
(p · h)(-8) = (-2.32 - 0.16)(-1.2 - 0.19)
(p · h)(-8) = (-2.48)(-1.39)
(p · h)(-8) = 3.4472
It is approximately equal to 3.
cos(3x) = cos(2x+x)
= cos(2x) cos (x) -sin(2x)sin(x)
