Answer:

OM = ON by using concurrency of Δs BOM and DON

Step-by-step explanation:

In the figure ABCD:

∵ AB // CD

∵ CB // AD

∵ In any quadrilateral If every two sides are parallel then

  it will be a parallelogram

∴ ABCD is a parallelogram

∴ AC and BD bisects each other at O ⇒ (properties of parallelogram)

∴ OD = OB ⇒ (1)

∵ BC // AD

∴ m∠CBD = m∠ADB ⇒ alternate angles

∵ M ∈ BC , N ∈ AD , O ∈ BD

∴ m∠MBO = m∠NDO ⇒ (2)

∵ BD intersects MN at O

∴ m∠MOB = m∠NOD ⇒ (3) (vertically opposite angles)

From (1) , (2) and (3)

∴ ΔBOM ≅ ΔDON

∴ OM = ON

Which point lies in the solution set of the inequality 1/2(x+2)+3y<8?
nasty-shy [4]

Note: Options are missing. So, the general solution of the given inequality is shown below.

Given:

The inequality is:

\dfrac{1}{2}(x+2)+3y

To find:

The point lies in the solution set of the given inequality.

Solution:

We have,

\dfrac{1}{2}(x+2)+3y

It can be written as:

\dfrac{1}{2}(x)+\dfrac{1}{2}(2)+3y

\dfrac{1}{2}x+1+3y

\dfrac{1}{2}x+3y

\dfrac{1}{2}x+3y

All the points that satisfy the above inequality are in the solution set of the given inequality.

For example (0,0).

\dfrac{1}{2}(0)+3(0)

0

This statement is true. It means (0,0) is in the solution set.

For example (0,3).

\dfrac{1}{2}(0)+3(3)

9

This statement is false. It means (0,3) is not in the solution set.

The graph of the inequality \dfrac{1}{2}x+3y is shown below.

All the points in the shaded region are in the solution set but the points on the boundary line are not in the solution set.

Lim x—&gt; -2 <br> sqrt(3x+10) -2/ x+2
snow_lady [41]

\displaystyle\lim_{x\to-2}\frac{\sqrt{3x+10}-2}{x+2}

Rationalize the numerator:

\dfrac{\sqrt{3x+10}-2}{x+2}\cdot\dfrac{\sqrt{3x+10}+2}{\sqrt{3x+10}+2}=\dfrac{(3x+10)-4}{(x+2)(\sqrt{3x+10}+2)}=\dfrac3{\sqrt{3x+10}+2}

where the x+2 factors in the numerator and denominator cancel. Then the limit is

\displaystyle\lim_{x\to-2}\frac{\sqrt{3x+10}-2}{x+2}=\lim_{x\to-2}\frac3{\sqrt{3x+10}+2}=\frac3{\sqrt4+2}=\boxed{\frac34}
