Answer:

19.313 m²

Step-by-step explanation:

We know that:

Area of octagon: A = 2(1+√2)a²
a = side

Work:

2(1+√2)a²
=> A = 2(1+√2)2²
=> A = 2(1+√2)4
=> A = 8(1+√2)
=> A = 8 + (√2 x 8)
=> A = 8 + 11.313
=> A = 19.313 m²

Hence, the area of the octagon is 19.313 m²

You are graphing rectangle ABCDABCDA, B, C, D in the coordinate plane. The following are three of the vertices of the rectangle:

vampirchik [111]

Answer:

The given coordinates of the vertices of rectangle ABCD are A(−2,2),B(4,2),C(4,−2).

We are to plot D on the graph.

Since ABCD is a rectangle, the abscissa of D will be that of A and the ordinate of D will be that of C.

Through (-2, -3), perp. to y = x- 2/1

WARRIOR [948]

Answer:

The equation of line passing through point ( - 2 , - 3 ) and slope 1 is y = x - 1

Step-by-step explanation:

Given equation of line as :

y = x - $\frac{2}{1}$

i.e y = x - 2

The standard equation of line is given as

y = m x + c ,

where m is the slope of the line and c is the y-intercept

Now, comparing the line , we have

Slope = m = 1

Now, The other line is perpendicular to the first line

So, from perpendicular property of line

The product of their slope = - 1

Let The slope of other line = M

So, m × M = - 1

Or, ( - 1 ) × M = - 1

or M = $\frac{- 1}{- 1}$

∴ M = 1

So , The slope of other line = M = 1

∵ The other line is passing through point ( x , y ) = ( - 2 , - 3 )

Now, satisfying the points and slope with standard line equation

I.e y = M x + c

or, - 3 = 1 × ( - 2 ) + c

or, -3 = - 2 + c

or, - 3 + 2 = c

∴ c = - 1

So, The intercept of other line = c = - 1

Now The equation of line with slope intercept

y = 1 × x + ( - 1 )

Or, y = x - 1

Hence The equation of line passing through point ( - 2 , - 3 ) and slope 1 is y = x - 1 Answer

Consider independently rolling two fair dice, one red and the other green. Let A be the event that the red die shows 3 dots, B b

max2010maxim [7]

Answer:

A & B are independent events. A & C, B & C are not independent events.

Step-by-step explanation:

Independent Events are the events, whose occurrences are completely unrelated to each other.

Event A 'Red dice getting 3' & Event B 'Green die getting 4' ; are unrelated to each other. The numbers on red dice & on green dice are not dependent on each other.

Event C 'Red & Green dice numbers showing sum = 7' is dependent on the numbers coming on red & green dice , i.e events A & events B respectively. So, event C is dependent on both events A & B.
