Answer:

$690.86

Step-by-step explanation:

100% from the original cost is: 2 x 863.57 = $1,727.14

40/100 = X/1727.14 (40 percent is what of 1,727.40) (%/100 = is/of)

(40 * 1,727.14) / 100 = $ 690.86

Solve the inequality.<br> 2(4+2x)&gt;5x+5<br> oxs-2<br> O X2-2<br> xs3<br> x23
mafiozo [28]

For this case we must resolve the following inequality:

2 (4 + 2x)> 5x + 5

Applying distributive property on the left side of inequality we have:

8 + 4x> 5x + 5

Subtracting 5 from both sides of the inequality:

8-5 + 4x> 5x\\3 + 4x> 5x

Subtracting 4x from both sides of the inequality:

3> 5x-4x\\3> x

Thus, the result is x

Answer:

x

What is the domain of the sine and cosine functions?
eimsori [14]

Answer:

domain of the sine and cosine functions is all real numbers

Step-by-step explanation:

range of both the sine and cosine functions is [−1,1]

graph can go left and right to infinity

graph goes up and down between 1 and -1

graph looks like a wave or

like U letters next to each other

UUUU

sine and cosine of an angle have the same absolute value as the sine and cosine of its reference angle.

3. Which ordered pair is on the line of the<br> graph for y = 10x?
Agata [3.3K]

<em>Note: It seems that you had forgotten to add the choices for this question. After a little research I am able to find the complete question, which is as follows:</em>

<em>Which ordered pair is on the line of the  graph for y = 10x?</em>

A) (0, 10)

B) (1, 10)

C) (10, 1)

<em>D) (10, 10)</em>

<em>So, I am answering based on this complete question. Hopefully, it would help in terms of clearing your concept.</em>

Answer:

The ordered pair (1, 10) is on the line of the  graph for y = 10x. So, the correct option is B) (1, 10). Also check the attached graph figure a.

.

Step-by-step explanation:

As the equation is given by

                                             y = 10x

<em>for A) (0, 10)   </em>

                                Put <em>(0, 10)  in </em>y = 10x ⇒ 10 = 0

So, the ordered pair (0, 10) does not satisfy the question. So, option <em>A) (0, 10)  is not true.</em>

<em> </em>

<em>for B) (1, 10)                       </em>

<em>                       </em>y = 10x

Put <em>(1, 10)  in </em>y = 10x ⇒ 10 = 10

So, the ordered pair (1, 10) satisfies the question. So, option B<em>) (1, 10)  is true. </em>Also check the attached graph figure a.

<em>for C) (10, 1)                       </em>

<em>                       </em>y = 10x

Put <em>(10, 1)  in </em>y = 10x ⇒ 1 = 100

So, the ordered pair <em>(10, 1)  does not</em> satisfy the question. So, option C<em>) (10, 1)  is not true.</em>

<em>for D) (10, 10)                       </em>

<em>                       </em>y = 10x

Put <em>(10, 10)  in </em>y = 10x ⇒ 10 = 100

So, the ordered pair <em>(10, 10) does not</em> satisfy the question. So, option <em>D) (10, 10)  is not true.</em>

<em>So, </em><em>from all the given options, the ordered pair (1, 10) is on the line of the  graph for y = 10x. So, the correct option is B) (1, 10). </em>Also check the attached graph figure a.
