Answer:
the actual answer is a(n)= 500 * ( 1 + 0.03) ^(n - 1) ;$579.64
Step-by-step explanation:
Hello!
First of all, we can subtract the stretching time. This gives us 20. If we divide by the four laps we get 5 minutes per lap.
Now, one lap is 400 meters (most tracks are), which is equal to 15,748.03 inches. This means it takes her five minutes to walk 15,748.03 inches. This is also equal to 300 seconds, so it takes her 300 minutes per 15,748.03 inches.
But if we round our big inches number to the nearest ten thousandth, we get 16,000, so in a simpler form her pace is 300/16,000. But we need to find in per second. Therefore we will divide by 300 to find how many inches she walks per second. This means she walks about 53.33 inches per second.
I hope this helps!

6x+1=2(3x-2)+5
6x+1=6x-4+5
6x+1=6x+1
Answer:
x = 5.5
Step-by-step explanation:
First, you need to distribute the -2:
-2(2+x) = -2x-4
Next you simplify:
x-2x = -x
Then you get all the x values on one side of the equation and everything else on the other side:
7-3x = -x-4 --> 11 = 2x
Finally, you isolate the x by dividing:
2x = 11 --> x = 5.5
Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is 
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become
we can arrange this properly to form a quadratic equation by grouping like terms.
solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
