Hello here is a solution :
f(x) = xsin(x)
f'(x) =( x)'sin(x) +x(sin(x))'
f'(x) = 1. sin(x)+x cos(x)
C
GIVE ME BRAINIEST PLEASE PLEASE
Thanks
Oi need it
Answer:
it's geometric
Step-by-step explanation:
geometric equations change by a rate witch means you multiply to get to the next number in the sequence
arithmetic you add to get to the next number in the sequence
Answer:
C = 79, B = 26 degrees
Step-by-step explanation:
tan C = 5.1323
To find C you use your calculator . Press tan-1 ( or it might be arctan) then the value 5.1323 Then ENTER.
C = 79 degrees to nearest degree.
cos B = 0.8954
B = 26 degrees
