Derivative of sec^2(x? it equals 2*sec^2(x*tan(x but why doesn't the ^2 part disappear? the derivative of sin^2(x = 2sinxcosx so i thought the ^2 part would disappear in the derivative of sec^2(x..

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
