The distance formula for two points in a plane is
D=sqrt( (x1-x2)^2 + (y1-y2)^2 )
From T to U
D= sqrt((80-20)^2 + (20-60)^2) = 72.11
Then flying from U to V
D= sqrt((20-110)^2 + (60-85)^2) = 93.4
So T to U to V = 72.11+93.4 = 165.5
BUT checking also T to V to U
From T to V
D= sqrt((80-110)^2 + (20-85)^2) = 71.6
Then from V to U
D= sqrt((110-20)^2 + (85-60)^2) = 93.4
So from T to V to U = 165
Pretty much the same both directions
So yes the answer is A
Step-by-step explanation:
The given sample space of S is = {ABC, ABD, ACD, BCD},
And from this sample space it can be deduced that;
(a) There can be four ways to choose the committee.
(b) There can be three ways in which person D is always included.
(c) And if persons B and C are necessarily be included, then there are two ways to form the committee.
Answer:
Area= 840
Step-by-step explanation:
Area= (20x13)x2+(10x12x1/2)x2+10x20
=520+120+200
=840
- Area=Two area of the triangle [13x20] + Two area of the rectangle + Under area (rectangle)- [10x20]
Equation: -34 + y = 7/12x
