$\bf \textit{area of a rectangle}=l\cdot w\qquad 
\begin{cases}
l=length\implies 4\cdot w\implies 4w\\
w=width\\
--------------\\

area=16
\end{cases}
\\ \quad \\
16=(4w)w\impliedby \textit{solve for "w"}$

What is the midpoint of the segment of the segment that would be created between points L and N on a graph?

il63 [147K]

Option A:

Midpoint of LN = (2, 3)

Solution:

In the given graph we can find the coordinates of L and N.

Coordinates of L = (–2, 3)

Coordinates of N = (6, 3)

Here, $x_{1}=-2, x_{2}=6, y_{1}=3, y_{2}=3$

Let us find the midpoint of the segment LN.

<u>Midpoint formula:</u>

$$\text { Midpoint }=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

$\begin{aligned}&=\left(\frac{-2+6}{2}, \frac{3+3}{2}\right)\\&=\left(\frac{4}{2}, \frac{6}{2}\right)\\&=(2,3)\end{aligned}$

Midpoint of LN = (2, 3)

Option A is the correct answer.

Hence the coordinates of the midpoint of the line segment LN is (2, 3).

Find the value of cos θ if the angle θ is in the third quadrant and sinθ= -0.8

Rudiy27

Correct option is D) -0.6.

<u>Step-by-step explanation:</u>

We have $sin\alpha = -0.8$ . Also, we know that $cos\alpha = \sqrt{1- (sin\alpha } )^{2}$ . Let's find out value of $cos\alpha$ using above formula:
