Help plz consider the sequence {4,6,8,10...}Find the explicit formula that defines the sequence. A) an = 2n + 2 B) an = 2n + 4 C
Alex777 [14]

A

this is an arithmetic sequence whose n th term ( explicit formula) is

a_{n} = a_{1} + (n - 1 )d

where d is the common difference and a_{1} the first term

here d = 10 - 8 = 8 - 6 = 6 - 4 = 2 and a_{1} = 4, hence

a_{n} = 4 + 2(n - 1 ) = 4 + 2n - 2 = 2n + 2 → A

A force of 18 lb is required to hold a spring stretched 8 in. beyond its natural length. How much work W is done in stretching i
Wittaler [7]

Answer: 18.75 lb.ft

Step-by-step explanation:

Given

Force required to stretch spring 8 in. is 18 lb

it can be written

\Rightarrow F=kx\\\Rightarrow 18=k(8)\\\\\Rightarrow k=\dfrac{18}{8}=\dfrac{9}{2}\ lb/in.

Work done in stretching from its natural length to 10 in.

\Rightarrow W=\dfrac{1}{2}kx^2\\\\\Rightarrow W=0.5\times \dfrac{9}{2}\times (10)^2\\\\\Rightarrow W=225\ lb.in.\ or\\\Rightarrow W=18.75\ lb.ft

The population of a town in 2000 was 430. The population is increasing at a rate of 0.9% every year. What will be the projected
Naddik [55]
If in 2000 there were 430 folksk, 2010 is 10 years later, thus t = 10

\bf \qquad \textit{Amount for Exponential Growth}\\\\&#10;A=I(1 + r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;I=\textit{initial amount}\to &430\\&#10;r=rate\to 0.9\%\to \frac{0.9}{100}\to &0.009\\&#10;t=\textit{elapsed time}\to &10\\&#10;\end{cases}&#10;\\\\\\&#10;A=430(1+0.009)^{10}\implies A=430(1.009)^{10}

Hannah has $482.75 in her savings account. She would like her account balance to be more than $1,250 before she buys a cell phon
Marina CMI [18]

The inequality equation would be 482.75+82.25x1250 <span>subtracting the amount that Hannah already has from the goal would amount to 767.25, therefore she only needs to save up to equal or more than this amount. Dividing this by 82.25 would then give us how many months this would take equal or greater than 9.33 months.</span>
