Answer:

B. 5√3 is your answer.

Step-by-step explanation:

This is an equilateral triangle, which means that all external sides (that make up the triangle) have the same measurement.

This means that line segment AC = 10.

Solve for the measurement of line segment AB. Line Segment AB is 1/2 of AC, making it: 10/2 = 5

Line AB = 5

Line AD = 10

This is a 1, √3, 2 triangle, in which:

1 = 5

2 = 10

Solve for √3. Multiply √3 with the 1:

5 x √3 = 5√3

B. 5√3 is your answer.

Answer; B

If the triangle is equilateral...then all sides are equal and the interior angles are all 60°

If line BD bisects <D...then the angle ADB = 30°(60° ÷ 2)

Then apply the trigonometry formula

where we state that....

Cos theta = BD/10

;Cos 30° = BD/10

; 10 Cos 30° = BD

Length BD = 10(square root of 3/2)

Which then gives us..BD = 5(square root of 3)

Please use for reference. Merci.

To find rate of change simply divide y/x.

hour 2: 56/2=28

hour 4: 125/4~about 31.3 or 31

hour 5: 164/5=32.8 or ~ 33

hour 8: 271/8 ~ about 34 or 33.875

hour 13: 404/13 ~ about 31 or 31.0769231

What numbers are the largest?

hours 5 and 8

Thus, the correct answer was option C.

Determine the measure of each segment then indicate whether the statements are true or false

kupik [55]

Answer:

$d_{AB}\ne d_{JK}$

$d_{AB}\ne \:d_{GH}$

$d_{GH}\ne \:d_{JK}$

Therefore,

Option (A) is false

Option (B) is false

Option (C) is false

Step-by-step explanation:

Considering the graph

Given the vertices of the segment AB

A(-4, 4)

B(2, 5)

Finding the length of AB using the formula

$d_{AB}\:=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$=\sqrt{\left(2-\left(-4\right)\right)^2+\left(5-4\right)^2}$

$=\sqrt{\left(2+4\right)^2+\left(5-4\right)^2}$

$=\sqrt{6^2+1}$

$=\sqrt{36+1}$

$=\sqrt{37}$

$d_{AB}\:=\sqrt{37}$

$d_{AB}=6.08$ units

Given the vertices of the segment JK

J(2, 2)

K(7, 2)

From the graph, it is clear that the length of JK = 5 units

$d_{JK}=5$ units

Given the vertices of the segment GH

G(-5, -2)

H(-2, -2)

Finding the length of GH using the formula

$d_{GH}\:=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

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

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

$=\sqrt{3^2+0}$

$=\sqrt{3^2}$

$\mathrm{Apply\:radical\:rule\:}\sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0$

$d_{GH}\:=\:3$ units

Thus, from the calculations, it is clear that:

$d_{AB}=6.08$

$d_{JK}=5$

$d_{GH}\:=\:3$

Thus,

$d_{AB}\ne d_{JK}$

$d_{AB}\ne \:d_{GH}$

$d_{GH}\ne \:d_{JK}$

Therefore,

Option (A) is false

Option (B) is false

Option (C) is false

Please no links and help me answer!!

12345 [234]

7: the answer is C because 3/4 divided by 2/3 equals 1 1/8 and C if you multiply 3/4 x 3/2 it equals 1 1/8

14: the answer is 18 because if you add all the numbers they picked you’ll get 6 then divide it by 1/3 you’ll get 18

Then the other 2 km not sure I’m sorry
