An arithmetic sequence with a third term of 8 and a constant difference of 5

Vanyuwa [196]

$\bf n^{th}\textit{ term of an arithmetic sequence} \\\\ a_n=a_1+(n-1)d\qquad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ d=\textit{common difference}\\ \hrulefill\\[0.5em] a_3=8\\ n=3\\ d=5 \end{cases} \\\\\\ a_3=a_1+(3-1)5\implies 8=a_1+(2)5 \\\\\\ 8=a_1+10\implies -2=a_1 \\\\\\ \begin{cases} a_1=-2\\ d=5 \end{cases}\implies a_n=-2+(n-1)d$

erastova [34]

Answer:

y - 7 = $\frac{14}{-11}$ (x + 8)

Step-by-step explanation:

Use the slope formula $\frac{y2 - y1}{x2-x1}$ to work out the slope

Then pick one point to insert into the formula y - y1 = m(x - x1)

If a certain trip takes 40 minutes when you travel 50 miles per hour, how many minutes would it take if you travel 40 miles per

vitfil [10]

Answer:

It would take 50 minutes

Step-by-step explanation:

<u>Distance, velocity and time</u>

The speed is the rate at which the distance changes with respect to time. If x is the distance, t is the time, the speed v can be obtained by

$\displaystyle v=\frac{x}{t}$

We know the trip takes 40 minutes when traveling at 50 miles/hour. The distance can be determined by isolating x in the above equation

$x=vt$

The given time is expressed in minutes, we need to convert it to hours. 40 minutes is $\frac{40}{60}=0.6666...\ hours$ . The distance is

$\displaystyle x=(50)(0.666..)=33.33\ miles$

If the speed was 40 miles/hour, the same distance would be covered in t hours, taken from the above equation as

$\displaystyle t=\frac{x}{v}$

$t=\frac{33.33}{40}=0.8333\ hours = 0.83333*60= 50\ minutes$
