Hello!

Looking at how you set up the proportion, it is correct.

Although, the multiplication is incorrect.

You are supposed to multiply 68 by 25 which comes out to 1700. Then, you should divide it by 100 to get x = 17.

\frac{x}{25} = \frac{68}{100}

100x = 68 * 25

100x = 1700 (divide both sides by 100)

x=17

Therefore, you should expect Sparky to catch it 17 times.

The function f(x)=125(0.9)x models the population of a species of fly in millions after x years.
SSSSS [86.1K]
A word to the wise:  It's  <span> f(x)=125(0.9)^x,   where ^ represents exponentiation.

In this case the ave. value over the interval [11, 15] is

 125(0.9)^15 - 125(0.9)^11
------------------------------------- = (125/4) [ 0.9^15 - 0.9^11)
               15 - 11                    =  (31.25) [ 0.2059 - 0.3138 ] = a negative result
                                              =  (31.25)(-0.1079) = -3.372  (av. r. of c.
                                                     over the interval [11,15] )

Do the same thing for the time interval [1,5].  Then compare the two rates of change.</span>

Which regular polygon has a minimum rotation of 45 degrees to carry the polygon onto itself?
lubasha [3.4K]

Answer:

Hence, a regular polygon that has a minimum rotation of 45 degrees to carry the polygon onto itself is:

A. octagon.

Step-by-step explanation:

We know that the for a regular polygon with 'n' sides the minimum rotation that can carry the polygon onto itself is:

\dfrac{360\degree}{n}

Here we are given the minimum angle of  rotation such that polygon is transformed to itself as 45 degree.

i.e. we have:

\dfrac{360}{n}=45\\\\n=\dfrac{360}{45}\\\\n=8

Hence, the number of sides of a polygon are 8.

Hence, the polygon is:

A. octagon.

( Since a polygon with 8 sides is called a octagon)
