What is the location of point F, which partitions the directed line segment from D to E into a 5:6 ratio? Negative one-eleventh
Elden [556K]

The location of point F, which partitions the directed line segment from D to E into a 5:6 ratio is \frac{1}{11}.

The given parameters:

  • <em>Partition of the line segment = 5:6</em>

The total segment of the directed line segment from D to E in the given ratio of 5:6 is calculated as follows;

total segment = 5 + 6 = 11

The value of each partition on the directed line segment is calculated as follows;

partition = \frac{1}{11} \times distance

The distance between point D and point E is calculated as follows;

D = 5 - (-4)\\\\D = 5 + 4\\\\D = 9

The partition of the two points (D to E) is calculated as follows;

partition = \frac{1}{11} \times 9 = 0.82

Thus, we can conclude that, the location of point F, which partitions the directed line segment from D to E into a 5:6 ratio is \frac{1}{11}.

Triangles Q R S and X Y Z are shown. Angles Q S R and X Z Y are right angles. Angles Q R S and X Y Z are congruent. The length o
kumpel [21]

Answer:

Three-fourths

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

∠QSR≅∠XZY ---> given problem

∠QRS≅∠XYZ ---> given problem

so

△QRS ~ △XYZ ----> by AA Similarity theorem

Remember that, if two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

That means

\frac{QS}{XZ}=\frac{QR}{XY}=\frac{RS}{YZ}

∠Q≅∠X

∠R≅∠Y

∠S≅∠Z

<em>In the right triangle XYZ</em>

Find the tangent of angle X

tan(X)=\frac{YZ}{XZ} ---> opposite side angle X divided by adjacent side angle X

substitute the given values

tan(X)=\frac{9}{12}

Simplify

tan(X)=\frac{3}{4}

Remember that

∠Q≅∠X

so

tan(Q)=tan(X)

therefore

tan(Q)=\frac{3}{4} ---->Three-fourths

Through: (4,- 4), perp. to y = -4x - 2
amid [387]

Answer:

Step-by-step explanation:

y = -4x - 2

slope of line = -4

slope of perpendicular to line = ¼

Point-slope equation for line of slope ¼, passing through (4,-4):

y+4 = ¼(x-4)

In slope-intercept form:

y = ¼x - 5

Round 3,942,588 to the nearest thousand.
olchik [2.2K]
Hey there! :D

3,942,588

The thousandths is where the 2 is. 

If the number behind the 2 is 5 or greater, we round up to 3.

It is, so round up:

3,943,000 <== rounded number

I hope this helps!
