Answer:
A. 2 sinx cosx - 1 + 2 sin^2 x.
Step-by-step explanation:
sin2x = 2 sinx cosx
cos2x = cos^2x - sin^2x
So sin2x - cos2x = 2 sinx cosx - ( cos^2x - sin^2x)
But cos^2 x = 1 - sin^2 x, so we have:
2 sinx cosx - (1 - sin^2 x - sin^2x)
= 2 sinx cosx - 1 + 2 sin^2 x.
Answer:
O = 50.3 degrees
Step-by-step explanation:
tan O = 89/74
tan O = 1.2027
O = 50.3 degrees
Answer:
domain of y = sqrt (x+4) is [-4, +inf)
Step-by-step explanation:
[-4, +inf), -4 is included because sqrt(-4 + 4) is defined but is undefined at the points from (-inf, -5].
Answer:
7 whole pieces
Step-by-step explanation:
There is 11.5 inches of rope.
Length of a piece = 1.5 inches
No . of pieces = total / unit length
= 11.5 / 1.5
= 7.667
There will be 7 whole pieces
