Sort the following objects by length. Place the shortest object at the top.

Alenkinab [10]

Answer:

Ok, here we have two points A and B.

The shorter object will be the second option, AB with a line on top, this is a segment, so the length of this object is equal to the distance between A and B.

The next one is AB with an arrow pointing to the right, this is ray, is a line that starts in A and passes through B, and continues infinitely.

The third will be the bottom option, AB with a double-arrow on top, this is the notation for a line that passes through A and B, and it extends to infinity in both directions.

Find the perimeter of the figure. You must show all your work to receive full credit

Usimov [2.4K]

Answer:

32.2 units

Step-by-step explanation:

The perimeter of the figure = AB + BC + CD + DE + EF + FA

AB = |5 - 11| = 6 units

BC = |-8 - 0| = 8 units

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

Let,

$C(11, 0) = (x_1, y_1)$

$D(6, -3) = (x_2, y_2)$

$CD = \sqrt{(6 - 11)^2 + (-3 - 0)^2}$

$CD = \sqrt{(-5)^2 + (-3)^2}$

$CD = \sqrt{25 + 9} = \sqrt{34}$

$CD = 5.8 units$ (nearest tenth)

DE = |6 - 4| = 2 units

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

Let,

$E(4, -3) = (x_1, y_1)$

$F(0, -6) = (x_2, y_2)$

$EF = \sqrt{(0 - 4)^2 + (-6 -(-3))^2}$

$EF = \sqrt{(-4)^2 + (-3)^2}$

$EF = \sqrt{16 + 9} = \sqrt{25}$

$EF = 5 units$

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

Let,

$F(0, -6) = (x_1, y_1)$

$A(5, -8) = (x_2, y_2)$

$FA = \sqrt{(5 - 0)^2 + (-8 -(-6))^2}$

$FA = \sqrt{(5)^2 + (-2)^2}$

$FA = \sqrt{25 + 4} = \sqrt{29}$

$FA = 5.4 units$ (nearest tenth)

Perimeter = 6 + 8 + 5.8 + 2 + 5 + 5.4

= 32.2 units

Divide the expressions: x + 1 / x + 2 ÷ 3x / x − 4.

slavikrds [6]

Answer:

Remember, $\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}*\frac{d}{c}=\frac{a*c}{b*d}$

Then,

$\frac{x+1}{x+2}\div\frac{3x}{x-4}=\frac{x+1}{x+2}*\frac{x-4}{3x}=\frac{(x+1)(x-4)}{3x(x+2)}=\frac{x^2-3x-4}{3x^2+6x}$ ,

Now, using long division of polynomies we have that

$\frac{x^2-3x-4}{3x^2+6x}=\frac{1}{3}-\frac{5x+4}{3x^2+6x}$

A number cube is rolled and a coin is flipped. Let H stand for heads and T for tails. What is the sample space for the experimen

tigry1 [53]

Answer: S={(1,H) , (1,T) , (2,H) , (2,T) , (3,H) , (3,T) , (4,H) , (4,T) , (5,H) , (5,T) , (6,H) , (6,T)}

Step-by-step explanation:

Given: A number cube is rolled and a coin is flipped.

Let H stand for heads and T for tails.

Then the sample space will contain pairs in which the first one shows the number on dice and the second one shows the the outcome for coin after dice is thrown.

Now, the required sample space will be

S={(1,H) , (1,T) , (2,H) , (2,T) , (3,H) , (3,T) , (4,H) , (4,T) , (5,H) , (5,T) , (6,H) , (6,T)}
