Arc= 2.pi.rAngle/360
14pi= 2.pi.18.Angle /360
Angle = 360.14.pi/2.18.pi
Angle = 140
Answer:
Step-by-step explanation:
(6u)+(-2u)=4u
(-7c)+(4c)=-3c
6=6
4u-3c+6
First find the slope of the line segment joining the points.
Slope = ((-5)-7)/(1-(-3)) = -3
The slope of any perpendicular to the line is 1/3
Find the midpoint of the line segment by taking the average of the coordinates.
x-coord of midpoint = (-3+1)/2 = -1
y-coord of midpoint = (7-5)/2 = 1
Midpoint : (-1,1)
Point-slope equation for line of slope 1/3 that passes through (-1,1):
y-1 = (1/3)(x+1)
The answer is 70 because 14x5 = 70
Answer:
1710
Step-by-step explanation:
GPA = 3,1 +- 0,6
0,6 = 2*STDEV
As it is a normal distribution, the interval (Mean +- 2*STDEV) includes 95% of the students.
1800 * 0,95 = 1710
