Answer:
(identity has been verified)
Step-by-step explanation:
Verify the following identity:
sin(x)^4 - sin(x)^2 = cos(x)^4 - cos(x)^2
sin(x)^2 = 1 - cos(x)^2:
sin(x)^4 - 1 - cos(x)^2 = ^?cos(x)^4 - cos(x)^2
-(1 - cos(x)^2) = cos(x)^2 - 1:
cos(x)^2 - 1 + sin(x)^4 = ^?cos(x)^4 - cos(x)^2
sin(x)^4 = (sin(x)^2)^2 = (1 - cos(x)^2)^2:
-1 + cos(x)^2 + (1 - cos(x)^2)^2 = ^?cos(x)^4 - cos(x)^2
(1 - cos(x)^2)^2 = 1 - 2 cos(x)^2 + cos(x)^4:
-1 + cos(x)^2 + 1 - 2 cos(x)^2 + cos(x)^4 = ^?cos(x)^4 - cos(x)^2
-1 + cos(x)^2 + 1 - 2 cos(x)^2 + cos(x)^4 = cos(x)^4 - cos(x)^2:
cos(x)^4 - cos(x)^2 = ^?cos(x)^4 - cos(x)^2
The left hand side and right hand side are identical:

Answer:
A possible solution is 60/2 = 30
Step-by-step explanation:
The given parameters are;
The dividend is a factor of 60
The divisor is a factor of 18
The quotient is a multiple of 3
The dividend is the amount divided
The dividend is the number that is dividing the dividend
The quotient is the result of the division operation
The given numbers to use are 60, 2, 30, and 18
Therefore one possible solution is 60/2 = 30
The dividend = 60 which is a factor of 60 (60 × 1 = 60)
The divisor = 2 which is a factor of 18 (2 × 9 = 18)
The quotient = 30 which is a multiple of 3 (3 × 10 = 30)
City A and City B are about 76.5 miles apart because 51*1.5 = 76.5
