The equation to find percent error is

\frac{actual-theoretical}{theoretical}*100

where actual is the value that actually came out (in this case, 11.5 km) and theoretical is the value that was supposed to come out (in this case, 10 km).  Just plug in the numbers and simplify.

\frac{actual-theoretical}{theoretical}*100\\\\\frac{11.5-10}{10}*100=\frac{1.5}{10}*100=15\%\ error

So, the true answer would be 15%.  Apparently, the question you're asking takes 11.5 as the theoretical and the 10 as the actual (which I personally disagree with)

If you plugged in the numbers that way, the answer comes out to 13.04%.  So, the correct answer for your answer choices is c. 13%

Find an equation for the perpendicular bisector of the line segment whose endpoints are (1,−8) and (9,2)
Len [333]

Answer: y+3=-\frac{4}{5}(x-5)

Step-by-step explanation:

For it to bisect the segment, we need to find the midpoint.

The midpoint is \left(\frac{1+9}{2}, \frac{-8+2}{2} \right)=(5, -3)

Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.

The slope of the given segment is \frac{-8-2}{1-9}=\frac{5}{4}, so the slope of the perpendicular bisector is -\frac{4}{5}

Thus, the equation of the line in point-slope form is \boxed{y+3=-\frac{4}{5}(x-5)}

Answer:

x=i√33−3,−i√33−3

hope this helps :)

Step-by-step explanation:

Subtract 5 from both sides of the equation.

(x+3)2=−28−

5 Subtract 5 from −28.

(x+3)2=−33

Take the square root of both sides of the equation to eliminate the exponent on the left side.

x+3=±√−33

Simplify the right side of the equation.

x+3=±i√33

The complete solution is the result of both the positive and negative portions of the solution.

x=i√33−3,− i√33 −3
