Arc length = radius* angle theta (in radians)
So angle 90 degree = 90*pi/180 radians= pi/2 radians
So arc length = 7.5* pi/2 cm = 11.8cm
So option A is correct.
Answer:
-2
Step-by-step explanation:
We have two points we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -11-1)/(-3 - -9)
= (-11-1)/( -3+9)
= (-12)/6
= -2
Answer:
3
Step-by-step explanation:
32 - 20 = 12
12/4 = 3
This assumes that by remainder they mean they twelve feet left over and not the twenty feet removed. This is likely what it means.
The vertex of the graph is (-2,1)
