Answer:
3.
A = 11
B = -4
C = 7
D = 27
Step-by-step explanation:
The length of a segment knowing the coordinates of its end points:
(x₁,y₁) and (x₂,y₂) is given by the formula:
Length = √[(x₁ - x₂)² + (y₁ - y₂)²]
T(1,4) ; A(4,4) ; P(3,0)
a) TA =√[(1-4)²+(4-4)²] → TA = 3
b) AP =√[(4-3)²+(4-0)²] →AP = √17 = 1.123
c) TP =√[(1-3)²+(4-0)²] → TA = √20 = 4.472
Perimeter = TA + AP + TP = 8.60
100% = 1.0
2.5% = 0.025
So now we know the decimal that corresponds to 2.5%, so all we have to do is multiply the price of the boat by this value in order to find the commission earned:
18 500 x 0.025 = $462.50
