4 squared+ 12 squared= c squared
16+144=160
Square root 160
so your answer would be 12.6
The answer is 80....they all have to add up to 180
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.
Answer:
351 m^2
btw
#1= 448 cm^2
#2=209pi cm^2
#3=351 m^2
and that's all I know hope it really helps we all need it sometimes (;
