Not all parallelograms have symmetry. Some examples of some that do have symmetry are a rhombus, square or rectangle. Parallelograms sometimes have a crucial symmetry in which the two lines intersect.

Alexeev081 [22]

Maya travels  4.19 feet/sec faster than Kelly !

Difference in distance is : 106.76-56.52 = 50.24 feet

<u>Step-by-step explanation:</u>

Here we have , The Carousel in the National Mall has 4 rings of horses. Kelly is riding on the inner ring, which has a radius of 9 feet. Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring is. We need to find In one rotation of the carousel, how much farther does Maya travel than Kelly . Let's find out:

Kelly is riding on the inner ring, which has a radius of 9 feet

Total distance traveled by Kelly is circumference of circle with radius 9 feet i.e.

⇒ Distance = 2\pi r

⇒ Distance = 2(3.14) 9

⇒ Distance = 56.52feet

Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring .

Total distance traveled by Maya is circumference of circle with radius (8+9=17) feet i.e.

⇒ Distance = 2\pi r

⇒ Distance = 2(3.14) 17

⇒ Distance = 106.76feet

Therefore , Difference in distance is : 106.76-56.52 = 50.24 feet

Now , Speed of both is give by

⇒ Speed_k_e_l_l_y=\frac{56.52}{12} = 4.71 feet/sec   And ,

⇒ Speed_M_a_y_a=\frac{106.76}{12} = 8.90 feet/sec

Faster Maya travels = 8.90-4.71 = 4.19

So , Maya travels  4.19 feet/sec faster than Kelly !

Answer:

  • E(-2, -1.5)

Step-by-step explanation:

<u>Coordinates of the points C and D:</u>

  • C(1, 6), D(-3, -4)

The point E has coordinates of (x, y).

The point E is at 3/4 of CD from C and 1/4 of CD from the point D.

<u>Find coordinates of E:</u>

  • x = -3 + 1/4(1 + 3) = -3 + 1 = -2
  • y = -4 + 1/4(6 + 4) = -4 + 2.5 = -1.5
