The formula to find the circumference of a circle given the information we know (the diameter), you could use the circumference formula of c=pi*diameter or:
c=3.14 * 4
c=12.56 is the circumference IF THE CIRCLE WAS WHOLE, but since we're working with a semicircle (and in this case, what looks to be exactly 1/2 of a circle), you could divide 12.56 by 2 and come up with 6.28 as the circumference of each of the semicircles.

Answer:

6.28

Step-by-step explanation:

3.14(pi) x 4ft = 12.56

12.56 divided by 2( because it is a semicircle)=

6.28!!

Five years ago, you invested $475 in corporate stock. You received dividends of $10 at the end of each quarter for two years. Yo

RUDIKE [14]

The rate of return earned on the investment of $475 five years ago in the corporate stock is 312.63%.

<h3>What is the rate of return?</h3>

The rate of return is the net gain or loss of an investment expressed as a percentage of the investment's initial cost.

It is given by the formula, R= {Vf - Vi}/{Vi} x 100.

Where:

R = Rate of return

Vf = final value, including dividends and interest

Vi = initial value

<h3>Data and Calculations:</h3>

Investment cost = $475

Dividends received:

1st two years = $80 ($10 x 8)

Three years = $180 ($15 x 12)

Total dividends received = $260 ($80 + $180)

Total revenue from sale = $1,700

Total proceeds = $1,960 ($1,700 + $260)

Total return = $1,485 ($1,960 - $475)

Rate of return = 312.63% ($1,485/$475 x 100)

Thus, the rate of return is 312.63%.

Hello!

$\large\boxed{x^{2} + x - 3 + \frac{4}{2x+3}}$

**Process pictured below**

When dividing, find how many times the first time in the divisor (2x + 3) fits into the first time of the dividend (2x³ + 5x² - 3x - 5). In this step, it fits x² times.

Multiply x² by the terms in the divisor and subtract from the dividend. Bring down the next term in the dividend to continue the process.

Repeat this step until you reach the last number. In this case, there was a remainder of 4. In order to write the remainder, you must express it over the divisor which makes it 4 / 2x + 3.
