Here's how you do it: you find all the distances between the three points and add them together to calculate the perimeter of the triangle. To calculate for the distance between two points, the formula is
d = √[(x2 - x1)² + (y2 - y1)²]
So, just take two points, assign x1 and x2 with corresponding y1 and y2, then you get the answer.
Points: D(1,4), E(3,-2), C(-3,1)
After substituting the answers would be:
DE = 6.3 units
CE = 6.7 units
CD = 5 units
Perimeter = 6.3 + 6.7 + 5
Perimeter = 18 units
Answer:
a) x-intercepts at -6 and 2
b) y-intercept at -12
c) minimum at (-2, -16)
Step-by-step explanation:
Answer:
6.74cm
Step-by-step explanation:
Area of circle = π * r * r = 35.6
Radius of circle = √(35.6 ÷ π) ≈ 3.37
Diameter of circle = 2 * r = 6.74cm
6 because if you take the 2.04679 then divide you would get 6.
