A = -0.7
B = -9/16 (0.5623)
C = -0.4
D = -5/16 (0.3125)
The last option is correct
Derivatives:
cos --> -sin
sin ----> cos
f' = cost - sint
f ' (pi) = cos(pi) - sin(pi)
= -1 -0
= -1
Answer:
Option D
Step-by-step explanation:
- You have to first find 4^x and then multiply it with two .
Not like this
(×)
Hence the variable has coefficient 4 as 4^x is multiplied.
The correct answer would be B because 88 divided by 11 would be 8 and therfore it would justift that the ration would be equal to 88:33
