1080-360 = 720
720-360=360
360-360=0
so tan 1080 = tan 0 = 0
Solution :
Let y = amount of caffeine at a given time in body.
n = number of hours
So 

ln Y = -0.01 n + C
At n = 0, Y = 130 mg
ln 130 = -0.01 x 0 + C
C = ln 130


When Y = 65



n = 69.315 hours
At n = 24 hours

Y = 102.26 mg
Answer:
14.90cm [a]
Step-by-step explanation:
To find x, we will apply " sine rule"
that is,
A/a=
B/b
here a= x A=90° B=70°anb b =14cm
so we input the values we have
1/x =0.94/14
cross multiply,
0.94x = 14
x = 14/0.94
=14.90cm
Answer:
The area is 768 square meters
Step-by-step explanation:
