Mike just hopped on the edge of a merry-go-round. What are his linear and angular speeds if the diameter of the merry-go-round i
dsp73

Step-by-step explanation:

Given that,

The diameter of the merry-go-round, d = 14 feet

Time taken, t = 6 seconds

Radius, r = 7 feet

The linear speed of the merry-go-round is given by :

v=\dfrac{2\pi r}{t}\\\\v=\dfrac{2\pi \times 7}{6}\\\\=7.33\ m/s

Also,

v=r\omega

Where

\omega is the angular speed

So,

\omega=\dfrac{v}{r}\\\\\omega=\dfrac{7.33}{7}\\\\=1.04\ rad/s

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.

Answer:

Step-by-step explanation:

Following changes will be there when the figure is transformed by the given rules.

1). Rule for transformation has been given as,

   (x, y) → (x, -y)

   Reflection across x axis.

2). (x, y) → (-x, -y)

   Rotation of 180° about the origin.

3). (x, y) → (x - 4, y)

   Shifted 4 units left horizontally.

4). (x, y) → (x, y + 3)

   Shifted vertically up by 3 units

5). (x, y) → (x - 1, y + 4)

   Shifted 1 units left horizontally and 4 units up vertically.

6). (x, y) → (4x, 4y)

   Dilated by 4 units.

Answer:

x = 5

Step-by-step explanation:

We need to find the value of x in this case.

For this, we need to consider that the triangles are similar. Now, we can find it as follows :

\dfrac{12}{3}=\dfrac{20}{x}\\\\x=\dfrac{20\times 3}{12}\\\\x=5

So, the value of x is equal to 5.
