Prove that the two circles shown below are similar.

Setler [38]

Answer:

The scale factor is $\frac{R_{A}}{R_{C}}=\frac{5}{2}$

We can say that both circles are similar.

Step-by-step explanation:

If we move the little circle to the center of the bigger circle, so the translate vector will be (3,5).

Now we realize that the bigger circle is just a dilation of the smaller circle, the scale factor is:

$R_{A}=5$

$R_{C}=2$

$\frac{R_{A}}{R_{C}}=\frac{5}{2}$

Therefore, we can say that both circles are similiar.

I hope it helps you!

Over a 10 year period, there were a total of 246 unprovoked shark bites in Florida. Assuming that shark bites occur at the same

Serggg [28]

Answer: Our required probability is 0.067.

Step-by-step explanation:

Since we have given that

Number of days in a year = 365

Number of years = 10

So, Number of days in 10 years = 365 × 10 = 3650

Number of unprovoked shark bites in Florida = 246

so, Probability that there will be at least one unprovoked shark bite on a given day is given by

$\dfrac{246}{3650}\\\\=0.067$

Hence, our required probability is 0.067.
