Please help geometry
sveta [45]

Answer:

The answer to your question is 11.4 units

Step-by-step explanation:

Data

A (-3, -1)

B ( 0, 3)

C ( 1, 2)

Perimeter = ?

Formula

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

Process

1.- Find the length between the points

dAB = \sqrt{0 + 3)^{2} + (3 + 1)^{2}}

dAB = \sqrt{3^{2}+ 4^{2}}

dAB = \sqrt{9 + 16}

dAB = \sqrt{25}

dAB = 5

dBC= \sqrt{(1 - 0)^{2} + (2 - 3)^{2}}

dBC = \sqrt{1^{2} + (-1)^{2}}

dBC = \sqrt{1 + 1}

dBC = \sqrt{2}

dAC = \sqrt{(1 + 3)^{2} + (2 + 1)^{2}}

dAC = \sqrt{4^{2} + 3^{2}}

dAC = \sqrt{16 + 9}

dAC = \sqrt{25}

dAC = 5

2.- Perimeter

P = AB + BC + AC

P = 5 + \sqrt{2} + 5

P = 10 + \sqrt{2}

P = 10 + 1.42

P = 11.4

Use an equation to find the value of k so that the line that passes through the given slope (1,3) , (5,k) m=2
scoray [572]

Answer:

The value of k with given points and slop = 11

Step-by-step explanation:

Given that a line passes through two points having slop (m) = 2

co ordinates of points are (1 , 3)   and (5 , k)

Now slop of line can be written as,

Slop = \frac{(y2 - y1)}{(x2 - x1)}

Or, m =  \frac{(y2 - y1)}{(x2 - x1)}

     2 =  \frac{(k - 3)}{(5 - 1)}

Or, 2 =  \frac{(k - 3)}{(4)}

So , k - 3 = 8

∴ K = 8+3 = 11

Hence the value of k with given points and slop = 11    Answer

A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 42 states. What is the probability that sh
Andrews [41]

Answer:

P(she selects the route of four specific ​capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷

Step-by-step explanation:

Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:

n=\frac{42!}{(42-4)!}\\n=42*41*40*39\\n=2,686,320\ ways

Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷
