Answer:
Step-by-step explanation:
Slope of the line segment = [(-8)-(-2)]/[(-9)-3]=-6/-12=1/2
Slope of the perpendicular bisector x slope of line segment = -1
Slope of perpendicular bisector = -2
Mid-point of line segment = ((-9+3)/2, (-8+(-2))/2) = (-3, -5)
The perpendicular bisector passes through the mid-point.
By point-slope form,
Answer:
This can be done in 3645 ways
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this problem, we have that:
1 Beethoven symphony, from a set of 9.
1 Mozart concerto, from a set of 27.
1 string quartets, from a set of 15.
So
This can be done in 3645 ways
