Area is square units so if length is tripled (times 3), area is times 3^2 or 9
so 600•9 = 5400 cm^2
Both Jerry and Tom start at the end of the pipe where the cheese is. Jerry then runs into the pipe at 20 m/s while Tom chases him at 10 m/s. When Jerry reaches the other end of the pipe, where Tom's cousin is, he turns around. Eventually, he reaches Tom again, so he turns around again. This continues until both Tom and Jerry reach the end of the pipe where Tom's cousin is.
We need to find the distance traveled by Jerry. We already know Jerry's speed, so we just need to find the time. We can do that using Tom's speed and the length of the pipe.
x = vt
100 m = (10 m/s) t
t = 10 s
So both Tom and Jerry run for 10 seconds. Since Jerry runs at a speed of 20 m/s, the distance he travels is:
x = vt
x = (20 m/s) (10 s)
x = 200 m
Jerry runs a distance of 200 meters.
this is a function
the input x = 2 so look for the line x=2
then look at the blue line, the function, and see at what point the line x=2 intersects the function. then find the value of the y coordinate of that point.
You can write out equations for both of these situations.
The first situation can be represented by f(x) = 382 + 2x, where 382 is the initial cost, x is the total amount of miles, 2x is the cost per additional mile, and f(x) equals to total that Jason has had to pay to drive his truck.
The second situation can be presented by g(x) = 379 + 5x, where 379 is the initial amount Jason will get paid, x is the amount of miles he's driven, 5x is the money he's being paid depending on how many miles he's driven, and g(x) is the total amount he's been paid.
You can graph these two equations on the computer or by hand to find where they will meet up. The place where they intersect will be the place where Jason breaks even. You can see on the graph I attached that, after one mile, the lines intersect and Jason spends and makes a total of 384 dollars.
Hope this helped you out! :-)
