Whats the differnece between parallel and perpendicular lines?

You run at a pace of 8.5 minutes per mile in a 26.2 mile marathon. How many minutes will it take finish?

algol [13]

8.5 minutes per mile is equivalent to

17 minutes
----------------
2 miles

and the reciprocal of that is

2 miles
-----------
17 min

Now multiply 26.2 miles by

17 min (17 min)* (26.2 mi)
------------ , obtaining ---------------------------
2 miles 2 mi

This simplifies to (17)(26.2)/2 minutes = 222.7 minutes,

or

222.7 minutes 1 hr
-------------------- * ------------ = 3.7 hours
1 60 min

Answer:

$\huge \boxed{\red{ \boxed{ - \cos(x) + C}}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

integration
PEMDAS

<h3>tips and formulas:</h3>

$\tan( \theta) = \dfrac{ \sin( \theta) }{ \cos( \theta) }$
$\sf \displaystyle \int \sin(x) \: dx = - \cos(x) + C$

<h3>let's solve:</h3>

$\sf \: rewrite \: \tan( \theta) \: as \: \dfrac{ \sin( \theta) }{ \cos( \theta) } : \\ = \displaystyle \int \: \frac{ \sin(x) }{ \cos(x) } \cos(x) \: dx \\ = \displaystyle \int \: \frac{ \sin(x) }{ \cancel{\cos(x) }} \: \cancel{ \cos(x)} \: dx \\ = \displaystyle \int \: \sin(x) \: dx$
$\sf \: use \: the \: formula : \\ \sf \displaystyle - \cos(x)$
$\sf add \: constant : \\ - \cos(x) + C$

$\text{And we are done!}$

Describe the Glide Reflection from the preimage triangle in Black to the image triangle and red

cestrela7 [59]

We want the final coordinate of K to become (-3,1). If you reflect across the y-axis, you transform

$(x,y)\mapsto(-x,y)$

So, we need to move K to (3,1), and then reflect it across the y-axis. Since K starts at (-1,4), we have to move it 4 units to the right and 3 units down.
