Please help solve 20 points.
Bond [772]

Answer: scroll down to find out :)

Step-by-step explanation:

This isn't a hard equation, so I would just use the points and figure something out.

Some obvious points are (3, 6), (6, 12), and (7, 14). Immediately, we notice that the y coordinate is 2 times the x coordinate.

So, the equation would be y = 2x.

<em>P.S. Let me know if I got it wrong! I'll be more than happy to fix it :)</em>

What is the slope of a line perpendicular to the line whose equation is 5x - y = -7.
BARSIC [14]

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

5x-y=-7\implies 5x-y+7=0 \\\\\\ \stackrel{\stackrel{m}{\downarrow }}{5} x+7=y\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}

so a line perpendicular to that one above will have a slope of

\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{5\implies \cfrac{5}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{5}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{5}}}

If θ is an angle in standard position that terminates in Quadrant IV such that cosθ = 3/5, then cosθ/2 = _____. -
Sveta_85 [38]

Answer:

cos \frac{\theta}{2}= 0.894.

Step-by-step explanation:

Given:

cos\ \theta= \frac35

We need to find cos \ \frac{\theta}{2}

Solution:

cos\ \theta= \frac35

First we will find the value of \theta.

Now taking cos^{-1} on both side we get;

\theta= cos^{-1} \ \frac{3}{5}\\\\\theta = 53.13

Now we will find the \frac{\theta}{2}.

\frac{\theta}{2} = \frac{53.13}{2} = 26.565

Now we will find cos \ \frac{\theta}{2} we get;

cos \frac{\theta}{2}=cos\ 26.565 = 0.894

Hence cos \frac{\theta}{2}= 0.894.
