The endpoints of a line segment AR are A(8,-2) and R(-4,1). What is the length of the AR?

Answers

Answer:

The length of the AR is  [tex]3\sqrt{17}[/tex]  or [tex]12.4[/tex] units.

Step-by-step explanation:

Given the endpoints of a line segment AR

A(8, -2)R(-4, 1)

We can calculate the length of AR using the formula

[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

In our case,

(x₁, y₁) = (8, -2)  (x₂, y₂) = (-4, 1)

Substituting (x₁, y₁) = (8, -2) and (x₂, y₂) = (-4, 1) in the formula

[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

        [tex]=\sqrt{\left(-4-8\right)^2+\left(1-\left(-2\right)\right)^2}[/tex]

        [tex]=\sqrt{\left(-4-8\right)^2+\left(1+2\right)^2}[/tex]            ∵ Apply rule:  [tex]-\left(-a\right)=a[/tex]

        [tex]=\sqrt{12^2+3^2}[/tex]

        [tex]=\sqrt{144+9}[/tex]

        [tex]=\sqrt{153}[/tex]

        [tex]=\sqrt{9\times 17}[/tex]

         [tex]=\sqrt{17}\sqrt{3^2}[/tex]          Apply radical rule:   [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}[/tex]

         [tex]=3\sqrt{17}[/tex]              Apply radical rule:   [tex]\sqrt[n]{a^n}=a[/tex]

         [tex]=12.4[/tex]

Therefore, the length of the AR is  [tex]3\sqrt{17}[/tex]  or [tex]12.4[/tex] units.

Answer:

Step-by-step explanation:

If i'm right, a triangle should add up to 180, so you add 39 and 102 to get 141. Then you subtract 141 from 180 and get 39

Answer:

39

Step-by-step explanation:

Remark

Every triangle has 180 degrees. The three angles must add to 180

Solution

x + 102 + 39 = 180

x + 141 = 180                     Subtract 141 from both sides.

x + 141-141 = 180-141

x = 39

Find the percent of change from the first value to the second. 72: 81 -
is means "From 72 to 81"*

Answers

Answer:

+12.5%

Step-by-step explanation:

This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.

(81 - 72)/72 * 100

Subtract 72 from 81 to get 9

9/72 * 100

Multiply 9 by 100 to get 900

900/72

Simplify the above fraction by cancelling out 9.

100/8

Divide 100 by 8 to get 12.5%

The percent of change is +12.5%

For the given triangles ΔABC ≈ ΔXYZ, the length of side N is, 45/4

What is similarity of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

The triangle, ΔABC

Triangle ΔABC and ΔXYZ similar,

So,  ΔABC ≈ ΔXYZ

And it is known that

for similar triangles, ratio of lengths of sides are equal for similar triangles

so, AB/AC = XY/XZ

⇒ 5/8 = N/18

⇒ N = 45/4

Hence, the value of N is 45/4

y-intercept 2x-5y=35​

Answers

Answer:

y=2/5x-7

Step-by-step explanation:

2x−5y=35

Step 1: Add -2x to both sides.

2x−5y+−2x=35+−2x

−5y=−2x+35

Step 2: Divide both sides by -5.

-5y/5=-2x+35/-5

y=2/5x-7

3 cans of tomato sauce for $1.49 or 5
cans of tomato sauce for $2.39

Answers

Answer:

5 can of tomato sauce for $2.39

Step-by-step explanation:

1.49/3 = $0.49

2.39/5 = $0.47

3 cans: divide $1.49 by 3 to get around 0.497 cents.

5 cans: divide $2.39 by 5 and it’s equal to 0.478 cents.

So 5 cans of tomato sauce for $2.39 is cheaper than the 3 cans for $1.49
