Describe the sequence of transformations that demonstrates the congruence between triangle ABC and triangle A´B´C´.
Shtirlitz [24]

Reflecting over the x axis means to perform the following tranformation:

(x,y) \to (x,-y)

So, you maintain the x coordinate, and change the sign of the y coordinate. The vertices become

A=(-4, 4)\to \hat{A} = (-4,-4),\quad B=(-2, 3)\to \hat{B} = (-2,-3),\quad C=(0, 7) \to \hat{C}=(0,-7)

Translating 3 units to the left means to perform the following transformation:

(x,y) \to (x-3,y)

So, you maintain the y coordinate, and decrease the x coordinate by 3. The vertices become

\hat{A} = (-4,-4) \to (-7,-4),\quad \hat{B} = (-2,-3)\to (-5,-3),\quad \hat{C}=(0,-7)\to (-3,-7)

So, as you can see, after these two transformation, the vertices A, B and C become A', B' and C'.

In a park, a sidewalk is built around the edge of a circular garden as shown. The sidewalk is 5 feet wide, and the garden measur
posledela

Answer:

63 feet.

Step-by-step explanation:

The total diameter of the circular garden is given by 5ft+ 10 ft + 5 ft= 20 feet

As the circumference of the circle = 2πr where r = radius obtained by dividing the diameter by 2. Here the diameter = 20 feet and r= d/2 = 20/2 = 10 feet

Putting the values in the circumference formula

Then C= 2(22/7) (10)= 62.85 feet

Rounding gives almost 63 feet .
