Which of the following are the features for the graph of the parent absolute value function? Select all that apply.
Burka [1]

absolute value graph looks like a V, with the vertex at the origin.

1. the domain (x-values) is: (∞, ∞)  TRUE

2. the range (y-values) starts at the vertex: [0, ∞)  FALSE

3. the function decreases when left of vertex and increases when right of vertex: decreases (-∞, 0)  TRUE

4. f(x) = |x| = +/-x

   f(-x) = |-x| = +/-x

  f(x) = f(-x) so the function is even  TRUE

5. every x-value has a corresponding y-value (there are no gaps) so the function is continuous.  TRUE

Answers: 1, 3, 4, 5

One pipe fills a storage pool in 20 hours, another pipe fills the same pool in 15 hours.
erica [24]
X=time  of the third person it would take to fill the pool 
We can suggest this equation:
6[(1/20) + (1/15) +(1/x)]=1
6[(3x+4x+60)/60x]=1
(7x+60)/10x=1
7x+60=10x
7x-10x=-60
-3x=-60
x=-60/-3
x=20

Answer: the third person alone would fill the pool in 20 hours .

Anyone help me please
andrew11 [14]

Solution,

As we have,

⇒2SinACosB=Sin(A+B)+Sin(A-B)

Now,

2sin7\alpha .cos2\alpha =sin9\alpha +sin5\alpha \\\\LHS=2sin7\alpha .cos2\alpha \\\\LHS=sin(7\alpha +2\alpha )+sin (7\alpha -2\alpha )\\\\LHS=sin9\alpha +sin5\alpha

<em>Hence, LHS=RHS</em>

Given: △ABC, D∈ AC m∠ABC=m∠BDA AB=2, AC=4 Find: AD and DC
Simora [160]

Answer:

The value of AD=1 and DC=3

Step-by-step explanation:

Given: ΔABC, D∈ AC m∠ABC=m∠BDA,  AB=2, AC=4

Diagram: Please find attachment.

To find: AD=? and DC=?

Calculation:

In ΔABC and ΔADB

   ∠ABC=∠ADB          (Given)

        ∠A=∠A               (Common)

Therefore,  ΔABC ≈ ΔADB  by AA similarity

If two triangles are similar then ratio their corresponding sides are equal

Therefore,

\dfrac{AD}{AB}=\dfrac{AB}{AC}

where, AD=?, AB=2, AC=4

\dfrac{AD}{2}=\dfrac{2}{4}

AD=\dfrac{2\times 2}{4}=1

AD=1

AD+DC=AC

1+DC=4

DC=4-1

DC=3

Hence, The value of AD=1 and DC=3
