Answer:
1
Step-by-step explanation:
CosASinB + SinACosB
Sin(A+B)
Sin(35+55) = Sin(90) = 1
Answer:yes
Step-by-step explanation: the answer does represent a function because if you were to put points in the line wherever, and connect them by drawing a line vertically, it would not cross two points.
The square root and the squared cancel each other out so it would just be 27 to the first power,which is 27
Step-by-step explanation:
Two lines that are perpendicular to each other has -1 as the product of thir gradient.
Since the gradient of the line y = 3 - x is -1, the gradient of the other line must be 1.
So y = x + c.
When x = 7, y = 1. 1 = 7 + c, c = -6.
Hence the equation of the line is y = x - 6.
