Answer:
y= -3/5 x -7.2
Step-by-step explanation:
-6 = 6/5 + b
b= - 7.2
Cot(x -pi/2) = (cos(x -pi/2))/(sin(x -pi/2)) = - sin x / cos x = - tan x
Answer:
The derivative is 
Step-by-step explanation:
From the question we are told that
The equation representing the reaction is 
Generally this equation can be represented as
Generally 
as a function of M is mathematically represented as
=>
12.5mg left at 6pm
Step-by-step explanation:
500mg x 15% = 75mg/hr
Taken at 8am and by 2pm that's 6/hrs 7 x 75mg/hr = 450mg
By 2pm only 50mg are left
Taken at 8am, by 6pm that's 10/hrs
With 50mg left and 4hrs to go
50mg ÷ 4 = 12.5mg
