Answer:

Arc=4 $\pi$

Step-by-step explanation:

The formula to get the length of arc is

Arc= degree x $\pi$ /180 x radius

Going by this formula, we can plug in a few numbers:

Arc= 80 x $\pi$ /180 x 9

Since it says to go off of term pi, we can simplify the 80 and the fraction and simplify.

Arc=80 $\pi$ /180 x 9

Arc=4 $\pi$ /9 x 9

Simplify, the nine cancels out

Arc=4 $\pi$

Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres

Crank

Answer: A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

Here the initial amount = n

Final amount after 1 years = 0.84n

The total change in the initial amount = n - 0.84n = 0.16 n

$\text{ The percentage change in the initial amount} = \frac{\text{ the total change in initial amount}}{\text{ Initial amount}}\times 100$

= $\frac{0.16 n }{n} \times 100 = 16\%$

Thus, the amount is decreases by 16% in one year,

⇒ Option A is correct.

Que es un numero compuesto y un numero primo

Lady_Fox [76]

<em>A compound number is a number that has more than one factor. A prime number is a number that only has a factor 1, and itself. For example, 17 is a prime number because on 1×17 will give you that. 24 is compound or composite because many factors like 1 and 24 or 2 and 12 or 6 and 4 multiply together to get that number.</em>
