Points N and R both lie on circle O. Line segment RQ is tangent to the circle at point R.
ANEK [815]

Answer:

Perimeter ΔRON = 18.66 units

Step-by-step explanation:

Complete Question has these information given as well:

  • Circle with center O
  • RN = QN
  • RQ = 5\sqrt{3}
  • ON = 5 units
  • RQ is tangent

<em><u>Now, we draw an image according to the information given. THe image drawn is attached.</u></em>

<em><u /></em>

Looking at the figure, we can say the perimeter of triangle RON would be:

RON = OR + ON + RN

We know according to tangent theorem, QN = QR

RN is equal to that as well and RN = 5\sqrt{3}

Now,

OR and ON is the radius, which is "5"

Perimeter of RON = 5 + 5 + 5\sqrt{3} = 10 + 5\sqrt{3} = 18.66 units

<u>Perimeter ΔRON = 18.66 units</u>

Find the amount in an account if 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months
storchak [24]

We have been given that in an account an amount of 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months.

We will use compound interest formula to find our answer.

A=Pcdot(1+\frac{r}{n}) ^{nT},

Where, P= principle amount, A= amount after T years, n= period of compounding and r = interest rate (decimal).

Let us substitute our given values in our formula.

A=7650(1+\frac{0.0915}{4} )^{(8.5\times4)}  

A=7650(1+0.022875)^{34}

A=7650(1.022875)^{34}  

A=7650\cdot 2.15758136398

A=16505.4974    

Therefore, after 8 years and 6 months our amount will be 16505.497.
