Hello everyone Here's a huge probleme I am struggling with since 2 days ! 

 

If someone could help me and explain me, it would be a huge gift for me!


 
An approximate linear model that gives the remaining distance, in miles, a plane must travel from Los Angeles to Boston is given by s(t) = 9000 - 600t where s(t) is the remaining distance t hours after the flight begins. 
 
(a) Find the veritcal and horizontal intercepts of s(t) 

 

(b) Explain what the horizontal and vertical interecept of s(t) represent in the context of this probleme 

I guess I will just said that  y = 90000 ( the miles ) and x = ( 600 ) Hours ? Right ? 

 

(c) Find the slope of s(t) 

 

(d) Explain what the slope of s(t) represents in the context of this probleme 

 

I really need help for that ! Please explain me :( 

 

Best, 

Thank you 

Thalys !

Hi Thalys,

You have had a lot of explaination and we are very pleased to teach you.

It is time to think about all that we have presented to you today.

Now, I know that you CAN answer some of these questions yourself.

I know that you can do part a.   I've see you do ones just like this.

 

s(t) = 9000 - 600t                      

t is time in hours

s(t) is speed at time t

 

(a) Find the veritcal and horizontal intercepts of s(t) 

The verical intercept is where t=0

The horizonal intercept is where s(t)=0

 

(b) Explain what the horizontal and vertical interecept of s(t) represent in the context of this problem.

I guess I will just said that  y = 90000 ( the miles ) and x = ( 600 ) Hours ? Right ? 

No, you need to write a sentence for each one.  Think about it, draw the graph of the line using the intercepts and think about what it is telling you.

 

 

(c) Find the slope of s(t) 

This is the number in front of t in the formula

Look at the last question i answered for you. 

 

(d) Explain what the slope of s(t) represents in the context of this problem.

I will talk more about this after you have properly looked at the others.

NOW stop panicking and collect your thoughts.

Think about everything we have shown you this morning. (maybe night for you)   :))

Just relax. Because it is a weekend, there aren't many prople online to help you. Don't sound desperate!!. Do the best that you can and your teacher will show you where your mistake is. That's how you learn, by making mistakes and learning from them. Good luck.

A hint for you: The y-intercet is 9000 and the x-intercept is 15

 

The y-intercet is the starting distance and the x-intercept is the number of hours.

 

The slope is the rate that the plane travels. 

 

I think that may help. Good luck smiley
