Find the perimeter of a quadrilateral with vertices at C (-1,2), D (-2,-1), E (2,-2), and F (1,1). Round to the nearest hundredt
stealth61 [152]
To answer, find the distance from point C to D, point D to E, point E to F, and point F to C. The formula for the distance is,
                                     d = sqrt ((x2 - x1)² + (y2 - y1)²)
  Point C to D                d1 = sqrt ((-3 - -2)² + (1 - 4)²) = 3.16 units
  Point D to E                d2 = sqrt ((1 - -3)² + (0 - 1)²) = 4.12 units
  Point E to F                 d3 = sqrt ((-1 - 1)² + (2 - 0)²) = 2.83 units
  Point F to C                 d4 = sqrt ((-1 - -2)² + (2 - 4)²) = 2.23 units 
Then, add up all the distances and the answer is 12.34 units. The closest answer is letter D.  Credit:Meerkat

If x = 4, what is the value of 2x2 - 7?
Fudgin [204]

Answer:

A) 25

Step-by-step explanation:

I am assuming that you mean: 2x² - 7.

2(4)^2 - 7\\\rule{150}{0.5}\\\rightarrow 2 *4^2 - 7\\\\\rightarrow 2 * 16 - 7\\\\\rightarrow 32 -7\\\\\rightarrow \boxed{25}

Find the slope of each line and then determine if the lines are parallel, perpendicular or neither. If a value is not an integer
Aleonysh [2.5K]

As given by the question

There are given that the point of two-line

\begin{gathered} (1,\text{ 7) and (5, 5)} \\ (-1,\text{ -3) and (1, 1)} \end{gathered}

Now,

From the condition of a parallel and perpendicular line

If the slopes are equal then the lines are parallel

If the slopes are negative reciprocal then the lines are perpendicular

If the slopes are neither of the above are true then lines are neither

Then,

First, find the slope of both of line

So,

For first-line, from the formula of slope

\begin{gathered} m_1=\frac{y_2-y_1}{x_2-x_1} \\ m_1=\frac{5_{}-7_{}}{5_{}-1_{}} \\ m_1=-\frac{2}{4} \\ m_1=-\frac{1}{2} \end{gathered}

Now,

For second-line,

\begin{gathered} m_1=\frac{y_2-y_1}{x_2-x_1} \\ m_1=\frac{1_{}-(-3)_{}}{1-(-1)_{}} \\ m_1=\frac{4}{2} \\ m_1=2 \end{gathered}

The given result of the slope is negative reciprocal because

\begin{gathered} -\frac{1}{2}=-(-\frac{2}{1}) \\ -\frac{1}{2}=2 \end{gathered}

Hence, the slope of line1 is -1/2, and slope of line2 is 2 and the lines are perpendicular.
