Answer:
A. Real number
Step-by-step explanation:
Fact :Real numbers that include decimal points are known as floating point numbers because the decimal floats within the numbers.
Answer: 4.01% interest rate
This value is approximate. It is rounded to the nearest hundredth of a percent.
============================================
Work Shown:
A = P*e^(r*t)
1833 = 1500*e^(r*5)
1833/1500 = e^(5r)
1.222 = e^(5r)
e^(5r) = 1.222
5r = Ln(1.222)
5r = 0.2004888607494
r = 0.2004888607494/5
r = 0.04009777214989
r = 0.0401
r = 4.01%
Answer: 144,000 typewriters
Step-by-step explanation:
Ok so, use the formula I= PRT.
Principal, rate, and time.
First, turn the % into 100..
Or just move the decimal two times to the right.
= 0.20
Next, Skip this. There is no next ♀
Finally, multiply. 120,000× 0.20 × 6
Giving you the answer of, 144,000 typewriters.
Hopefully this helps ♀

Answer:
The general solution of the system is
Step-by-step explanation:
To verify that the system ![X^{'} =\left[\begin{array}{cc}1&3\\3&1\end{array}\right] X](https://tex.z-dn.net/?f=X%5E%7B%27%7D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%263%5C%5C3%261%5Cend%7Barray%7D%5Cright%5D%20X)
has the solutions given,
First, we determine the Eigen Values β of the matrix of the form 
Using |A-βI|=0, where I is the Identity Matrix, we have:
Subtracting matrices
Taking the determinant
We determine the eigen vector using
When 
= -2,
which implies that 
and thus
When = 4,
which implies that 
and thus
A general solution of the system is given as
where the c's are the eigen vectors.
Thus the general solution is
