Converting from rectangular coordinates to polar coordinates involves setting

. Since the left hand side matches

perfectly, the equation's rectangular coordinate form is

.
Answer:

Step-by-step explanation:
Cost of 1 CD's 
Cost of 1 Hat 
Cost of 1 flying disk 
Number of CD's = 11
Number of hats = 26
Number of flying disks = 53
Station's cost for the promotional items is calculated as follows: ![\left[\begin{array}{ccc}4.50&3.25&1.25\end{array}\right] \left[\begin{array}{ccc}11\\26\\53\end{array}\right]=4.50(11)+3.25(26)+1.25(53)\\\\=49.5+84.5+66.25\\\\=\$200.25](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4.50%263.25%261.25%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D11%5C%5C26%5C%5C53%5Cend%7Barray%7D%5Cright%5D%3D4.50%2811%29%2B3.25%2826%29%2B1.25%2853%29%5C%5C%5C%5C%3D49.5%2B84.5%2B66.25%5C%5C%5C%5C%3D%5C%24200.25)
Answer:
420
Step-by-step explanation:
Because 7+7=420 and poopie
First, fine the slope of the lines.
m=3-6/4-2
m=-3/2
To find the perpendicular slope of this, find the opposite reciprocal, or 2/3
Use formula y=mx+b to find the equation of this line.
3=(2/3)(4)+b
3=b+8/3
3-8/3=b+8/3-8/3
1/3=b
Now, plug in the values
y=2/3x+1/3, or B
