The e vertex of the decagon will be in the top position after rotating it counterclockwise by 3 times the smallest angle of rotation.

Which vertex will be in the top position of the regular decagon?

A regular decagon has 10 sides of equal lengths with points labeled 'a' through 'j' clockwise. It is given that the point a is the top-left point. Hence, the the vertex which is in the the top position currently is 'b'.

Now, the smallest angle of rotation will be the angle between the two sides of the decagon.

In the first rotation by the smallest angle in counterclockwise direction, point 'c' will come to the top position. In the second rotation by the smallest angle in counterclockwise direction,  point 'd' point will become the top most vertex. Finally, after the third similar rotation, 'e' vertex will be in the top position of the decagon. (Refer the attached diagram)

When the area in square units of an expanding circle is increasing twice as fast as its radius in linear units, the radius is...
enot [183]

Answer:

c. \frac{1}{\pi}

Step-by-step explanation:

We have been given that the area in square units of an expanding circle is increasing twice as fast as its radius in linear units

We will use derivatives to solve our given problem.

We know that area (A) of a circle is equal to A=\pi r^2.

Let us find derivative of area function with respect to time.

\frac{dA}{dt}=\frac{d}{dt}(\pi r^2)

Bring out constant:

\frac{dA}{dt}=\pi \frac{d}{dt}(r^2)

Using power rule and chain rule, we will get:

\frac{dA}{dt}=\pi(2r)* \frac{dr}{dt}

\frac{dA}{dt}=2\pi r*\frac{dr}{dt} Here \frac{dr}{dt} represents change is radius with respect to time.

We have been given that area of an expanding circle is increasing twice as fast as its radius in linear units. We can represent this information in an equation as:

\frac{dA}{dt}=2\frac{dr}{dt}

2\pi r* \frac{dr}{dt}=2\frac{dr}{dt}

2\pi r=2

\frac{2\pi r}{2\pi}=\frac{2}{2\pi}

r=\frac{1}{\pi}

Therefore, the radius is \frac{1}{\pi} and option 'c' is the correct choice.

Rectangle ABCD and right triangle DCE have the same area. They are joined to form a trapezoid, as shown. What is DE?
vfiekz [6]
Since the areas are the same  (5 x 6 = 30 units), and the height of the triangle (DC) is 5 so the length of the triangle must be 12.  (1/2 of  5 x 12 is also 30)

So now we use the Pythagorean theorem

a² + b² = c²   we have 5² + 12² = c²  or 25 + 144 = c²  or 169 = c²

The square root of 169 is 13 so side DE is 13 units.
