A bug was sitting on the tip of a wind turbine blade that was 24 inches long when it started to rotate. The bug held on for 5 ro

tations before flying away. How far did the bug travel before it flew off?

Answer:

240π  

Step-by-step explanation:

Turbine blade that was 24 inches long is the radius of the circle the bug travels.

So the Circumference is = 2rπ = 2*24*π = 48π

The bug held on for 5 rotations. so the distance that the bug travels = 5*48π  = 240π

1)
The distance between points A and B is;
d= \sqrt{(x2-x1)^{2} + (y2-y1)^{2} } \\
d= \sqrt{(1-5)^{2} +(12+8)^{2}}\\ 
d= \sqrt{(-4)^{2} + (20)^{2}}\\
d=\sqrt{16+400}\\
d=\sqrt{416}\\
d=4\sqrt{26}, 
and if you wanted to you could measure out the legs of that hypotenuse using the slope between A and B, but I'm going to show you the easier way;
Δx = 4
Δy = -20
So from the midpoint, add 4 to the x-value and subract 20 from the y-value.
{(5+4),(-8-20)}
(9,-28) is the endpoint.

2)
Do the same thing as I did above;
d= \sqrt{(x2-x1)^{2} + (y2-y1)^{2} } \\ 
d= \sqrt{(5-(-3))^{2} +(5-(-4))^{2}}\\
d=\sqrt{(5+8)^{2}+(5+4)^{2}}\\
d=\sqrt{(13)^{2}+(9)^{2}}\\
d=\sqrt{169+81}\\
d=\sqrt{250}\\
d=5\sqrt{10}
So 5\sqrt{10} is the distance.

Sorry for the delay, life delayed me a ton ,:D

Are these integers please help
dolphi86 [110]

Answer:

63/9 = 7 -> Yes

-94 -> Yes

30/6 = 5 -> Yes

-16/3 ~ -5,33 -> Nope

-29,86 -> Nope

Step-by-step explanation:

Integers are whole Numbers.

For example 1,2,3,4,5...

The numbers between numbers are rational numbers.

Fir example:

1,2 ( between 1 and 2)

3,8 (between 3 and 4)

2,6 (between 2 and 3)
