The general equation of the circle is:

(x-h)^{2} +(y-k)^{2} =r^{2}

(h,k) is the center of the circle and r is the radius. We are given the coordinates of the center. So we can write the equation of the circle as:

(x+4)^{2} +(y+3)^{2} =r^{2}

In order to complete the equation, we need the radius of the circle. Using the given point we can find the radius. Using the point in the above equation, we get:

(6+4)^{2}+(2+3)^{2}=r^{2} \\  \\ 
100+25=r^{2}

Thus the value of r² is 125. Using the value in equation of the circle, we get:

(x+4)^{2} +(y+3)^{2} =125

The radius of the circle is √125.

11000 is compounded semiannually at a rate of 12% for 21 years. Find the total amount in the compound interest account
marishachu [46]

\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\dotfill &\$11000\\
r=rate\to 12\%\to \frac{12}{100}\dotfill &0.12\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{semiannually, thus twice}
\end{array}\dotfill &2\\
t=years\dotfill &21
\end{cases}


\bf A=11000\left(1+\frac{0.12}{2}\right)^{2\cdot 21}\implies A=11000(1.06)^{42}\implies A\approx 127127.359416

Divide each set to see if the answers are identical:

A: 3/2 = 1.5

  6/3 = 3

Answers are not the same so this is not proportional.

B: 20/4 = 5

24 /6 = 4

Answers are not the same so this is not proportional.

C: 27/9 = 3

81/27 = 3

Answers are the same so this is  proportional.

D: 8/2 = 4

16/8 = 2

Answers are not the same so this is not proportional.

The answer is C.

1. The time taken for the water to fall that much is 0.2 s

2. The initial speed of the water is 4 m/s

<h3>1. How to determine the time </h3>
  • Height (h) = 20 cm = 20 / 100 = 0.2 m
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Time (t) =?

h = ½gt²

0.2 = ½ × 9.8 × t²

0.2 = 4.9 × t²

Divide both side by 4.9

t² = 0.2 / 4.9

Take the square root of both side

t = √(0.2 / 4.9)

t = 0.2 s

<h3>2. How to determine the initial speed</h3>
  • Horizontal distance (s) = 80 cm = 80 / 100 = 0.8 m
  • Time (t) = 0.2 s
  • Initial speed (u) =?

s = ut

Divide both sides by t

u = s / t

u = 0.8 / 0.2

u = 4 m/s
