Answer:
Step-by-step explanation:
If the lower right corner were present, the area would simply be
A = L * W
A = 16 * 8
A = 128
Since the lower right corner is not present, it's area is not there.
A = L * W
A = 10 * 3
Area = 30 cm^2
So the area of the green figure is
Area = 128 - 30
Area = 98 cm^2
The question is missing. Here is the complete question.
Let y = ![\left[\begin{array}{ccc}2\\6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%5C%5C6%5Cend%7Barray%7D%5Cright%5D)
and u = ![\left[\begin{array}{ccc}7\\1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%5C%5C1%5Cend%7Barray%7D%5Cright%5D)
. Write y as the sum of a vector in Span(u) and a vector orthogonal to u.
Answer: y = ![\left[\begin{array}{ccc}\frac{21}{10} \\ \frac{3}{10} \end{array}\right] + \left[\begin{array}{ccc}\frac{-1}{10}\\ \frac{57}{10} \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Cfrac%7B21%7D%7B10%7D%20%5C%5C%20%5Cfrac%7B3%7D%7B10%7D%20%5Cend%7Barray%7D%5Cright%5D%20%2B%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Cfrac%7B-1%7D%7B10%7D%5C%5C%20%5Cfrac%7B57%7D%7B10%7D%20%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation: The sum of vectors is given by
y = 
+ z
where is in Span(u);
vector z is orthogonal to it;
First you have to compute the orthogonal projection of y:
= proj y = 
Calculating orthogonal projection:
![\left[\begin{array}{c}2\\6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D2%5C%5C6%5Cend%7Barray%7D%5Cright%5D)
.![\left[\begin{array}{c}7\\1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D7%5C%5C1%5Cend%7Barray%7D%5Cright%5D)
= ![\left[\begin{array}{c}9\\6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D9%5C%5C6%5Cend%7Barray%7D%5Cright%5D)
. = ![\left[\begin{array}{c}49\\1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D49%5C%5C1%5Cend%7Barray%7D%5Cright%5D)
![y_{1} = \frac{3}{10}.\left[\begin{array}{c}7\\1\end{array}\right]](https://tex.z-dn.net/?f=y_%7B1%7D%20%3D%20%5Cfrac%7B3%7D%7B10%7D.%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D7%5C%5C1%5Cend%7Barray%7D%5Cright%5D)
![y_{1} = \left[\begin{array}{c}\frac{21}{10} \\\frac{3}{10} \end{array}\right]](https://tex.z-dn.net/?f=y_%7B1%7D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D%5Cfrac%7B21%7D%7B10%7D%20%5C%5C%5Cfrac%7B3%7D%7B10%7D%20%5Cend%7Barray%7D%5Cright%5D)
Calculating vector z:
z = y -
z = ![\left[\begin{array}{c}2\\6\end{array}\right] - \left[\begin{array}{c}\frac{21}{10} \\\frac{3}{10} \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D2%5C%5C6%5Cend%7Barray%7D%5Cright%5D%20-%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D%5Cfrac%7B21%7D%7B10%7D%20%5C%5C%5Cfrac%7B3%7D%7B10%7D%20%5Cend%7Barray%7D%5Cright%5D)
z = ![\left[\begin{array}{c}\frac{-1}{10} \\\frac{57}{10} \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D%5Cfrac%7B-1%7D%7B10%7D%20%5C%5C%5Cfrac%7B57%7D%7B10%7D%20%5Cend%7Barray%7D%5Cright%5D)
Writing y as the sum:
![y = \left[\begin{array}{c}\frac{21}{10} \\\frac{3}{10} \end{array}\right] + \left[\begin{array}{c}\frac{-1}{10} \\\frac{57}{10} \end{array}\right]](https://tex.z-dn.net/?f=y%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D%5Cfrac%7B21%7D%7B10%7D%20%5C%5C%5Cfrac%7B3%7D%7B10%7D%20%5Cend%7Barray%7D%5Cright%5D%20%2B%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D%5Cfrac%7B-1%7D%7B10%7D%20%5C%5C%5Cfrac%7B57%7D%7B10%7D%20%5Cend%7Barray%7D%5Cright%5D)
Answer:
the original amount is $1,642
Step-by-step explanation:
The computation of the original amount is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
So,
Present value = Future value ÷ (1 + rate of interest)^number of years
= $3,024.56 ÷ (1 + 0.26 ÷ 2)^5
= $1,642
Hence, the original amount is $1,642
