Answer: 243, 729

Step-by-step explanation:

1, 3, 9, 27, 81 is a geometric sequence where r = 3

a₁ = 1

a₂ = 1 x 3 = 3

a₃ = 3 x 3 = 9

a₄ = 9 x 3 = 27

a₅ = 27 x 3 = 81

To find the next two terms, multiply the previous term by 3:

a₆ = 81 x 3 = 243

a₇ = 243 x 3 = 729

HELP ASAP PLEASE

Solution (1) using angles of sectors:

Area of A = pi r^2 x 90/360 = 4.9

Area of B = pi r^2 x 270/360 = 14.2

Check: Area of A/B = 4.9/14.72 = 1/3 (as given)

Solution (2) using given info:

Area of B + Area of A = area of circle

Area of B + 1/3 Area of B = 3.14 * (2.5)^2 = 19.625

4/3 Area of B = 19.625

Area of B = 3/4 * 19.625

Area of B = 14.72

Area of A = 1/3 * 14.72 = 4.9

There is more solutions to this problem , like polar coordinate integration , and so on. for more just request.

if 500 is deposited into an account earning 6 percent simple interest what is the future value in 6 years how do you work it put

djverab [1.8K]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$500\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
t=years\to &6
\end{cases}
\\\\\\
A=500(1+0.06\cdot 6)$
