Well you have to make the powers line up so we know r^4 is the highest and you work your way down so

0r^4-5r^3-4r^2-3r
R^4+0r^3-4r^2+3r

So now that they are lined up by power we solve (keep in mind that the 0r's are place holders and have no value)

R^4-5r^3-8r^2

That's your answer

It is now 3:15 pm. Is it possible to drive 135 miles and arrive before 5:00 pm if ypu drove 55 mph? Explain your answer
Troyanec [42]
Well, how long will it take you to drive 135 miles at 55mph?

at 55 mph, you're doing 55 miles every hour, so we can simply get the quotient of 135/55 and that's how many hours it'll take you to drive 135 miles at that speed.

\bf \cfrac{135}{55}\implies \cfrac{27}{11}\implies 2\frac{5}{11}~hours\implies \textit{about 2hrs, 27 minutes}

so, it takes you that long, however, from 3:15 to 5:00pm there are only 45mins + 60mins or 1hr and 45 minutes, namely 1¾ hr.

so 2hrs and 27 minutes is much later than 1¾ hr, so, no dice, you can't arrive at 5pm, actually you'll arrive around 5:42pm.

A tree 5 feet tall grows an average of 8 inches each year. Write and graph an equation to model the tree's height h after x year
Stolb23 [73]
Okay my example will be for if you watched that tree for like 5 years and I can`t really put in a graph here so sorry about that

The equation is basically the original height, 5 foot, and multiply it by the number of years you`ve been watching it grow for example when you watch it for 6 years then it will be the original height of 5 foot multiplied by the number years it has been since you look at it which is 6 years. 5 * 6 = 30 so after 6 years it will grow 30 inches.
1st year: 5 foot
2nd year: 5 foot * 2 = 10 inch increase in height
3rd year: 5 foot * 3 = 15 inch increase in height
4th year: 5 foot * 4 = 20 inch increase in height
5th year: 5 foot * 5 = 25 inch increase in height
So basically the equation is 5 foot * the number of years its been = total increase in height

I hope this helps
