bearing in mind that perpendicular lines have negative reciprocal slopes, let's find firstly the slope of AC.

$\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{6}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{6-1}{1-2}\implies \cfrac{5}{-1}\implies -5 \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{\cfrac{-5}{1}}\qquad \qquad \qquad \stackrel{reciprocal}{\cfrac{1}{-5}}\qquad \stackrel{negative~reciprocal}{\cfrac{1}{5}}}$

so, we're really looking for the equation of a line whose slope is 1/5 and that passes through (3,3)

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{3}) ~\hspace{10em}slope = m\implies \cfrac{1}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-3=\cfrac{1}{5}(x-3) \implies y-3=\cfrac{1}{5}x-\cfrac{3}{5} \\\\\\ y=\cfrac{1}{5}x-\cfrac{3}{5}+3\implies y=\cfrac{1}{5}x+\cfrac{12}{5}$

Tony's dorm is 7.5 miles far from the library.

Step-by-step explanation:

Given points are;

(4,0) and (12,6)

$x_1=4,\ \ \ \ \ \ \ y_1=0\\x_2=12,\ \ \ \ \ \ y_2=6$

Using point distance formula;

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$Distance=\sqrt{(12-4)^2+(6-0)^2} \\Distance=\sqrt{(8)^2+(6)^2}\\Distance=\sqrt{64+36}\\Distance=\sqrt{100}\\Distance=10\ units$

One unit represents 0.75 miles, therefore,

10 units = 0.75*10 = 7.5 miles

Tony's dorm is 7.5 miles far from the library.

How do you calculate the residuals of a scatter plot?

Aloiza [94]

Hello

A residual is the difference between the observed y-value (from scatter plot) and the predicted y-value (from regression equation line). It is the vertical distance from the actual plotted point to the point on the regression line.

Have a nice day kid!

Formula to find the missing number Faces:15 vertices:15 edges:?

gtnhenbr [62]

Answer:

Step-by-step explanation:

Euler's formula is

V - E + F = 2

Givens

V = 15

E = 15

F = ?

Solution

15 - 15 + F = 2

F = 2

I'm not sure this makes sense, but it is what the formula gives you.

Answer:

$17

Step-by-step explanation:

10 x 2.25 = 22.5

10 x .50 = 5

22.5 -5 = 17

I think this is correct. Sorry if it isn't though!!!!!!
