Answer:

Yes, Triangles ABE and CDB are similar by AA Similarity Postulate

Step-by-step explanation:

we know that

If two triangles are similar, then its corresponding angles are congruent

In this problem

Triangles ABE and CDB are similar by AA Similarity Postulate (the three interior angles are congruent)

Because

If BE is perpendicular to AD

then

BE is parallel to DC

therefore

m<EBA=m<DCB -----> by corresponding angles

m<AEB=m<DBC=90 ----> right angles

m<EAB=m<BCD -----> the sum of the interior angles of a triangle must be equal to 180 degrees

There is a rule:

One input(x-value) can only have one output(y-value) in order to be a function.

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

The 1st option is not a function because the inputs 9 and 10 have more than one output.

The 2nd option is not a function because the input 3 has more than one output.

The 3rd option is a function because each input only has one output.

The 4th option is not a function because the input 5 has more than one output.

John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21 About how far does

Agata [3.3K]

Answer:

John ski down the mountain is 1285.37 feet.

Step-by-step explanation:

Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.

To find : About how far does John ski down the mountain ?

Solution :

We draw a rough image of the question for easier understanding.

Refer the attached figure below.

According to question,

Let AB be the height of mountain i.e. AB=1200 feet

The angle of depression is 21 i.e. $\theta=21^\circ$

We have to find how far does John ski down the mountain i.e. AC = ?

Using trigonometric,

$\cos\theta = \frac{AB}{AC}$

$\cos(21)= \frac{1200}{AC}$

$AC=\frac{1200}{\cos(21)}$

$AC=1285.37$

Therefore, John ski down the mountain is 1285.37 feet.

Answer:

$w\geq -2$

Step-by-step explanation:

Distribute the 5 into the parentheses (multiply them both by 5)

$15.5w+6.5\geq -25$

Subtract the 6.5 from -25.

$15.5w\geq -31.5$

Divide -31.5 by 15.5.

$w\geq -2$
