How many times does a dragonfly's wing beat per minute

marshall27 [118]

<span>A dragonfly beats its wings about 30 times a second. This is necessary to allow the insect to keep itself airborne, due to the relative weight of its body. Luckily, dragonflies have two sets of wings, or they would have to work even harder to stay up in the air.</span>

Can someone please help?!

Bond [772]

Answer:

1. $R_{90} (x,y)=(-y,x)$

2. $R_{180} (x,y)=(-x,-y)$

3. $R_{270} (x,y)=(y,-x)$ .

Step-by-step explanation:

Let us assume a point (x,y) in the co-ordinate plane on which the transformations will be applied.

Now, we know that 'rotation' is a transformation that turns that image to a certain degree about a point.

So, the given transformations gives us the forms as:

1. When we rotate an ( x,y ) by 90° about origin counter-clockwise, the resultant co-ordinate is ( -y,x ).

So, the function form is $R_{90} (x,y)=(-y,x)$ .

2. When we rotate an ( x,y ) by 180° about origin counter-clockwise, the resultant co-ordinate is ( -x,-y ).

So, the function form is $R_{180} (x,y)=(-x,-y)$ .

3. When we rotate an ( x,y ) by 270° about origin counter-clockwise, the resultant co-ordinate is ( y,-x ).

So, the function form is $R_{270} (x,y)=(y,-x)$ .
