Item 15 Question 1 Show that quadrilateral WXYZ with vertices W(−1,6), X(2, 8), Y(1, 0), and Z(−2,−2) is a parallelogram by find
Aliun [14]

Answer:

Multiple answers

Step-by-step explanation:

A parallelogram is a flat shape that has four sides. The two sets of opposite sides are parallel and of equal length to each other.

To prove that our figure is a parallelogram we first get the slope of our sides.

The formule we use to get the slope is:

m = \frac{y-y1}{x-x1}

  1. first we have the W-Z side that it's supossed to be parallel to X-Y side

if we use our formule to calculate the slope of W-Z:

\frac{6-(-2)}{-1-(-2)}  =  \frac{8}{1}  =  8

if we use our formule to calculate the slope of X-Y:

\frac{8-0}{2-1}  =  \frac{8}{1}  =  8

  • We know that parallel lines will never intersect because they have the same slope, therefore W-Z side is parallel to X-Y side

2. Then we have the W-X side that it's supossed to be parallel to Z-Y side

if we use our formule to calculate the slope of W-X:

\frac{6-8}{-1-2}  =  \frac{-2}{-3}  

if we use our formule to calculate the slope of Z-Y:

\frac{-2-0}{-2-1}  =  \frac{-2}{-3}  

  • We know that parallel lines will never intersect because they have the same slope, therefore W-X side is parallel to Z-Y side

Then we have to prove that the parallalel sides are equal length to each other.

The formule we use to get the distance between two points is:

\sqrt{(x2-x1)^{2}+(y2-y1)^{2}  }

We calculate the lenght of the W-Z side that it's supossed to be equal to X-Y side:

W-Z = \sqrt{(-1-(-2))^{2}+(6-(-2))^{2}  } =   \sqrt{65}

X-Y = \sqrt{(2-1)^{2}+(8-0)^{2}  } = \sqrt{65}

So the W-Z side have the same lenght to X-Y side.

We calculate the lenght of the W-X side that it's supossed to be equal to Z-Y side:

W-X = \sqrt{(-1-2)^{2}+(6-8)^{2}  } =   \sqrt{13}

Z-Y = \sqrt{(-2-1)^{2}+(-2-0)^{2}  } = \sqrt{13}

So the W-X side have the same lenght to Z-Y side.

If you invest $8,600 at a 3 95% simple annual interest rate, approximately how long will it take for you to have a toad of $21,0
Mariana [72]

Answer:

37 years.

Step-by-step explanation:

Interest = PRT/100  where P = Initial Amount, R = rate, T = the time.

So we have the equation:-

8600 + 8600*3.95 * T / 100 = 21000

8600 + 33970T / 100 = 21,000

8600 + 339.7T  = 21000

339.7T = 21000 - 8600

T =  (21000 - 8600) / 339.7

T =  36.5 years
