Answer:
the first formula
Step-by-step explanation:
the graph is y=cosx and cosx=sin(x+90)
Answer:
2
Step-by-step explanation:
parallel lines have same slope.
y = 2x + 5
y = mx + b
m is the slope
b is y-intercept
The answer is 16 pi - 16. The area of each triangle is 8, so both triangles are 16. The area of the circle is pi times the radius squared, 16 pi.
Answer:
y=x+4
Step-by-step explanation:
2y=2x+4 simplifies down to y=x-2. Since the two lines are parallel, they have to have the same slope, but different y-intercepts. This means that we just have to find the y-intercept that will allow our line to pass through (-5, -1).
If we input the coordinates into what of our equation we have thus far (y=x+b), we just have to find what b needs to equal to make the equation true.
-1=-5+b -1=-5+4
b = 4 -1=-1
