Answer:
D. local maximum at the point (4, 18)
Step-by-step explanation:
Check the critical points and end points to test for any absolute extrema over the given interval.
We have
cos3x/(sinxcosx)
we know that
cos(3x) can be written as
cos(2x +x)=[cos2x*sinx-sin2x*cosx]
Using this value of cos(3x) in given equation
[cos2x*sinx-sin2x*cosx]/(sinxcosx)
[cos2x*sinx]/(sinxcosx)-[sin2x*cosx]/(sinxcosx)
[cos2x]/(cosx)-[sin2x]/(sinx)---------> secx*cos2x-csecx*sin2x
the answer is the option <span>B.) secxcos2x-cscxsin2x </span>
Answer:
x= -6
Step-by-step explanation:
2(x-4)-3(2x+2)=2(x+11)
multiply numbers in parenthesis by 2 and multiply numbers in parenthesis by -3 and multiply parenthesis by 2.
2x-8-6x-6=2x+22
subtract 2x to 2x
-8-6x-6=22
subtract -8 to -6 but since there both negatives the equation is addition.
-14-6x=22
move constant to the right and change -14 as a positive.
-6x=22+14
add 22 to 14
-6x=36
divide both sides by -6
x= -6
Answer:
25%
Step-by-step explanation:
Add all the cold orders
(8+12+5)
Then, you know there are 100 orders
25/100=25%
