Which graph represents the solution set of the system of inequalities?
Nimfa-mama [501]
Well first we need to change the format of the equations to slope-intercept, or y=mx+b.
So the first one (x + y < 1) will be changed to   y < -x + 1.
The second one (2y ≥ x - 4) will be changed to   y <span>≥ x/2 - 2.
Now we can analyze each graph.
In every single graph the first equation (y < -x + 1) is graphed correctly.
Now for the second equation, we can see that only the first and last graph correctly format to the equation.
Now for the shading:
The first equation shows us that y is less than -x +1, making the shading go under the dotted line. (to the left)
The second equation shows us that y is greater than or equal to x/2 - 2, making the shading go above the line. (also to the left)
Therefore, when we shade, the overlapping shading is correctly formatted in the first graph.
Hope this helped, comment any questions you have for me.</span>

In the triangle above, what is sin A
Shkiper50 [21]

Answer:

\large\boxed{\sf sin(A)=0.5}

Step-by-step explanation:

A right angled triangle is given to us and we would like to find out the value of sin(A) .

From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

\longrightarrow A = 30^o

On using sin both sides ,

\longrightarrow sin(A) = sin30^o

As we know that the value of sin30° = 1/2. So;

\longrightarrow sin(A)=\dfrac{1}{2}

Simplify by converting it into decimal ,

\longrightarrow \underline{\underline{sin(A) = 0.5}}

<u>Hence</u><u> </u><u>option</u><u> </u><u>B</u><u> </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u>

And we are done!

Please help<br>mathematics ​

<h3>Given:</h3>
  • Trapezium
<h3>To find:</h3>
  • Length of BC
  • Value of "x"
<h3>Solution:</h3>

We can divide the given shape into a triangle and a rectangle.

We'll have to use Pythagoras Theorem.

\large\boxed{Formula:{a}^{2}={b}^{2}+{c}^{2}}

In this question we have to find the hypotenuse so we'll have to add.

Let's substitute the values according to the formula.

BC= {6}^{2}+{7}^{2}

BC= 85

BC =  \sqrt{ 85}

\boxed{BC=9.22 \: cm}

Now, we can find the value of "x"

  • Adjacent= 7 cm
  • Opposite= 6 cm
  • Hypotenuse= 9.22 cm

We can use any one from SOHCAHTOA.

Here I'm using tan.

\large\boxed{Formula: tan(a)= \frac{opp}{adj}}

Let's substitute the values according to the formula.

tan \: x= \frac{6}{7}

We'll have to use tan inverse.

x= {tan}^{-1}(\frac{6}{7})

\boxed{x=40.6°}
