The formula for percentage error is:
Ross got the approximate area as 12, while the actual area was 11.8. So, let's plug it in to the formula.
Multiply 0.0169 by 100 to make it into a percent.
0.0169 * 100 =
1.69%Ross's percentage error is
1.69%.
100 and 110.
You would have to add 100 to both sides. This is because to complete the square, you need to take half of the x term and square it.
Step-by-step explanation:
1 week = 7 days
given 7 days = 14 hours of practice
and let x be the number of hours spent on practicing and y the number of days.
from the above expression we can have the equation,
using the equation when y = 10,

Answer:
Part 1: or
Part 2:
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get (since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:
Then in this case you turn y=f(x), but the system did it for you, so all you have to put is .
For the second part you must replace x with 2 since you need to find f(2).
Your answer for part 2 is .
