cos(2x+x)
=cos (2x)cosx-sin(2x)sinx
=(1-2sin^2x)cosx-2sinxcosx*cos x
=cos x-2 sin ^2 x cos x-2 sin^2 xcos x
=cos x-4sin^2 x cos x
=cos x {1-4(1- cos ^2 x)}
=4 cos ^3x -3 cos x
Answer:
B. The Range is the set of real numbers greater than or equal to zero
C. The Domain is the set of all real numbers .
Step-by-step explanation:
The Domain is the set of real numbers for which the function is defined. In this case, the Domain is the set of all real numbers .
The Range is the set of real numbers that are connected to the elements of the domain. In this case, you see that only real numbers above (or in the) x-axis are connected to the x-values of the domain. Then another answer to check is;
B. The Range is the set of real numbers greater than or equal to zero.
Answer:
Hi! Is there a picture?
Step-by-step explanation:
Answer:
1080
Step-by-step explanation:
if 10 percent are left handed that means that 90 percent are right handed

- number of people that are right handed = 1080
Sandy is 42 and Karen is 27
Because 27+15=42 and 42+27= 69
