1. First transformation is rotation rotation of 180 about the origin. This transformation has a rule:

(x,y)→(-x,-y).

If points E(-2,-4), F(-1,-1), D(-2,-1) are vertices of triangle EFD, then

E(-2,-4)→E''(2,4),
F(-1,-1)→F''(1,1),
D(-2,-1)→D''(2,1).

2. Second transformation is translation 1 unit left with a rule

(x,y)→(x-1,y).

Then

E''(2,4)→E'(1,4),
F''(1,1)→F'(0,1),
D''(2,1)→D'(1,1).

Answer: 1st: rotation of 180 about the origin; 2nd: translation 1 unit left.

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (5, 7)

Point (-4, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-4 - 5)^2 + (3 - 7)^2}$
[√Radical] (Parenthesis) Simplify: $\displaystyle d = \sqrt{(-9)^2 + (-4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{81 + 16}$
[√Radical] Simplify: $\displaystyle d = \sqrt{97}$
[√Radical] Approximate: $\displaystyle d \approx 9.8$

BabaBlast [244]

We now that the probability that one randomly selected car will crash in the year is 0.047800478.
If a family has three cars, this means that the probability that some of their car will crash in the next year is : 3 * the probability that one randomly selected car will crash = 3 * 0.047800478. = 0.143401434
