Using the product rule, which states that (uv)' = u'v + uv':
If y = (e^-2x)(sec3x)
y' = (e^-2x)'(sec3x) + (e^-2x)(sec3x)'
y' = -2(e^-2x)(sec3x) + (e^-2x)(3 sec3x tan3x)
y' = 3(e^-2x)(sec3x tan3x) -2e^-2x (sec3x)
This matches choice B.
The solution to the absolute value equation 2|x + 8| - 4 = 16 is x = 2 or x = -18
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Given the equation:
2|x + 8| - 4 = 16
2|x + 8| = 20
|x + 8| = 10
x + 8 = 10 or -(x + 8) = 10
x = 2 or x = -18
The solution to the absolute value equation 2|x + 8| - 4 = 16 is x = 2 or x = -18
