Answer:

(sin x)^2*(sec x) is positive in QII

Step-by-step explanation:

(sin x)^2 is always 0 or positive. Here x lies in QII.

sec x is positive when the adjacent side is positive and negative when the adjacent side is negative. In QII the adjacent side is positive.

In summary, (sin x)^2*(sec x) is positive in QII

Write the point-slope form of the equation of the line through the given points through: (-3,-1) and (-2,5)?

nevsk [136]

The point-slope form of the equation of the line through the given points through: (-3,-1) and (-2,5) is y + 1 = 6x + 18

Solution:

Given, two points are (-3, -1) and (-2, 5)

We have to find that a line that passes through the given two points.

First let us find the slope of the line that passes through given two points.

The slope of line "m" is given as:

$\text { slope of line } m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\text { where, }\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right) \text { are two points on line. }$

Now, let us find the line equation using point slope form

$y-y_{1}=m\left(x-x_{1}\right)$

where m is slope

$\begin{array}{l}{\text { Then, line equation } \rightarrow y-(-1)=6(x-(-3))} \\\\ {\rightarrow y+1=6(x+3)} \\\\ {\rightarrow y+1=6 x+18}\end{array}$

Hence the point slope form is y + 1 = 6x + 18

In all, there are 48 of them. This is further explained below.

<h3>What are pennies?</h3>

Generally, The cent is the name given to the coin that is worth one cent in the United States. It is also often referred to as the "penny."
