Answer:

95.73

Step-by-step explanation:

2 decimal points is what the question MEANS:

formula for finding a cirlce (and this is not from the internet)

r^2 times pi

(5.52)^2 times pi

which (5.52) squared becomes a sickly: 30.4704 in decimals

lets say you WANT to keep the decimals, then multiply 30.4704 by 3.14159265359 and absolutely get every single decimal place added in and THEN round it to 2 decimal places (once i didn't do this, i got bad grades in math class)

the answer is 95.7255847919

the decimal place of this is 95.73 not 95.72 or something,

the answer is 95.73

Nostrana [21]

Answer:

The amount of money due to Beth-Ann at the end of this period​ is $27, 300.

Step-by-step explanation:

The amount at the end of a period, when simple interest is being charged is:

Amount (A) = Principal (P) + Interest (I)

Here interest is computed using the formula:

I=P\times R\times T

It is provided that:

P = 24,000

R = 11%

T = 15 months = 1.25 years

Compute the Interest as follows:

I=P\times R\times T

  =24000\times 0.11\times 1.25\\=3300

The interest earned is, <em>I</em> = $3,300.

Compute the amount of money due to Beth-Ann at the end of this period​ as follows:

A=P+I

   =24000+3300\\=27300

Thus, the amount of money due to Beth-Ann at the end of this period​ is $27, 300.

What is the explicit formula for this sequence ? -9,-3,3,9,15,...
chubhunter [2.5K]

Answer:

             B.\ \ a_n=(-9)+(n-1)6  

Step-by-step explanation:

a_1=-9\,,\ a_2=-3\,,\ a_3=3\,,\ a_4=9\,,\ a_5=15...\implies d=6

{-9-(-3)=6 and 3-(-3)=6 and 9-3=6 and 15-9=6}

An arithmetic sequence is:   a_n=a_1+(n-1)d

a_1=-9\quad and\quad d=6

a_n=-9+(n-1)\cdot6
