Sorry I can't solve it.
Firstly, the equation is wrong. It is supposed to be <span>81 ≠ </span><span>30.25
Second of all, this is the best I got </span>81= <span><span>−<span>76 <span>(<span>cos<span>(r) </span></span></span></span></span>+ <span>106.25</span></span>
Answer:
V=2c
Step-by-step explanation:
![\\[Looking at the relationship of the numbers in the table, we can see which ones will work right off the bat.]\\[Our first numbers are both zero, so we cant do anything significant there.]\\[Next row, however, we can start doing the process of elimination.]\\\left[\begin{array}{ccc}1&2\\2&4\\3&6\\4&8\\5&10\end{array}\right]\\ \\[After plugging in the formulas to see if they're true, the only one that works every time is V=2c.]\\[That is your answer.]](https://tex.z-dn.net/?f=%5C%5C%5BLooking%20at%20the%20relationship%20of%20the%20numbers%20in%20the%20table%2C%20we%20can%20see%20which%20ones%20will%20work%20right%20off%20the%20bat.%5D%5C%5C%5BOur%20first%20numbers%20are%20both%20zero%2C%20so%20we%20cant%20do%20anything%20significant%20there.%5D%5C%5C%5BNext%20row%2C%20however%2C%20we%20can%20start%20doing%20the%20process%20of%20elimination.%5D%5C%5C%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%5C%5C2%264%5C%5C3%266%5C%5C4%268%5C%5C5%2610%5Cend%7Barray%7D%5Cright%5D%5C%5C%20%5C%5C%5BAfter%20plugging%20in%20the%20formulas%20to%20see%20if%20they%27re%20true%2C%20the%20only%20one%20that%20works%20every%20time%20is%20V%3D2c.%5D%5C%5C%5BThat%20is%20your%20answer.%5D)
1. (7 − 3i) • (2 − i)
It is simplified as follows:
14 - 7i -6i - 3
11 - 13i

Answer:
do you know how to calculate c
Step-by-step explanation:
Answer: $634.40
Step-by-step explanation:
